Yes I had a little training, but for the most part trained many folks to excel beyond their expectations.
Done some crazy stuff in the past and with consistency its been fun and I enjoy all the science and the challenge within it.

Was able to get a little testing in at 700 the last few weeks in between work. The test load groups went from 8” down to 4.5” & 4” then down to 2.25” and this weekend with good overcast conditions the last test group circled in red had a center to center or bottom to bottom of 3/4”. I was more concerned about vertical then the left or rights, my aim point was a red horizontal line on the target face. The Extreme Spread is in single digits and the average speed with 505 gr. Flat Line’s is at 3192 fps also we are not seeing any change in diameter in the case head area and grove so the pressure is good and not stretching the primer pocket area.

Here’s a little info to compare
The BC based off of Doppler Radar for the 505 grain
G1 BC = 1.2 based off of 3150 fps
G7 BC 0.595 based off of 3150 fps
As stated I am at a mild pressure charge with the 416 using 505s running 3105 fps with 199 grains I will be pressure testing 200, 201 yet.
Even at a speed of 3105 and in Raton, NM with a DA of 8200 there I will be Supersonic at a Mach 1.11 out to 3875 yards before dropping into transonic. If I find my load has a sweet spot a little faster it just gains more range in the Supersonic stage and yields a little less wind drift but I still believe in slow and consistent versus having to have the fastest Hot Rod in which is more finicky.
Numbers always look good but you still have to study the mirage and pay attention to any updrafts or eddies I always say mirage is your freind it can tell you a lot of info. And we haven’t even mentioned earth rotation yet when you get past 2000 yards.
When you only have 3 attempts to hit a small target under a time restraint you use all the science and skill possible.
Pictured a 505 grain next to a common Hornady 308 round and then a loaded Warner 416 as well as the back of a round fired with 199 grains.
I wanted to add for the folks that are interested at 3105 fps it equates to 1975 fps and 4373 lbs of energy yet at 2000 yards on impact and at 3000 yards we have 1527 fps and 2614 lbs of energy.

Last year the 375 pushing a 400 grain at 3316 fps in which was the load charge used for the 2 mile averaged a 1” to 2” vertical at 800 yards. We were able to push the 400 grain to 3400+ fps but wanted to detune the load due to New Mexico temps and having to shooting up to 15 rounds in 9 minutes or less in which was hard on the throat when burning 192 grains of powder and stuffing it down a small 375 hole.

Hopefully things heal up soon and you can get back at pulling the trigger. Yes I am trying to get ready for the 2 mile, June will be here before you know it and testing equipment is a bit more challenging.
We should catch up some time for coffee or something and visit.

Its my long range rifle used for shooting steel while laying on the ground prone, kicks like a 20ga. Complete ready to fire, rifle, scope and bipod 40lbs

Check out Tactical Rx at Tacticalrx.com
They did a pair of shooting glasses with my progressive bifocals prescription in them for when I am on the ground shooting prone with the rifle.
They specialize in shooting glasses for pistol shooters.
I have not came across anyone else that works with shooters and correction eyeware like these folks.

What part of central Wisconsin are you from. Just curious if your anywhere close.

Thanks, yes that was the link.

Tom
What are you suggesting as far as your question.
Also anyone that may interested in some good reading material, a while back I came across this and tried to paste a link here for folks to see but failed. So do a google search for – What the Pro’s use King of 2 Mile edition.
Cheers
Good luck this fall folks
2nd attempt I give up
Nice looking rifle Tom, I have just a slight double front pin with or without my glasses on. Probably a little better with them off. I still should be fine for aiming.
JH
Thanks Randy, we did the testing to verify drops and dope in Colorado on our way to the KO2M event in Raton, New Mexico at the NRA Whittington center. The G1 BC on the 361 grain Warner Flat Line 375 cal ran at .965
It was the luck of the draw on who shot when with the winds in the canyons and mountain sides under a 9 minute time restraint on all 5 targets combinend with 15 shots max. It was fun that out of 49 shooters from all over the world only 4 people hit the 16″ Coldbore target at 1699 and only one shooter tore up the paint on all the qualifier targets including the Coldbore 1699 – one shot, 1543 allowed five shots, 1722 allowed 3 shots, 1889 allowed 3 shots and 1953 yards and allowed 3 shots. You had to hit the target to move on. We averaged a 11″ vertical on the 1953 target with the 3 shots allowed in qualifying. Just sayin it was a Wisconsin flat lander that wrecked the paint on all 
and we had some good wind when I shot on the second day.
Fun stuff when we were shooting at the ranch in Colorado at the 3040 yard mark mentioned in OP above and with full value winds and repeat hits on a 36″ plate we were dialing and holding for 45′ of wind drift.
Picture below is right after rattling the course at NM the owner of McRee chassis asked for a pic it was a fun event.

You can’t go wrong with a Surgeon action or build. They are very highly rated and dependable. A close friend of mine and gunsmith – shooting coach actually worked and shot for them.
260, 6.5×47 or Creed?
Cheers

Grouse one of my favorite case funnels that I use, I dump my pan from the dispenser or from my beam scale into this and then into the case.

Theres nothing wrong with a scope with a adjustable turrets or hash marks in the scope be it dots or hash marks. I don’t understand why this would be a disadvantage as Grouse stated, but to me would be a advantage. You will have the ability to use your 100 yard zero and hold over using your hash marks or dial up a few hundred and aim dead on. There is no fumbling but yet more so having the ability to be more accurate.
There are a lot of high quality scopes available at anyone’s price range – glass is glass some will give you a little more advantage then others but what is a true priority is repeatability in the turret as far as running up and down.
Also with this purchase download a Ballistic program into your smart phone, this can be – Shooter, Applied Ballistics, Trasol they will cost you anywares from $10.00 to $35.00 this investment will save you so much money, time and success in the field. This is a area that I see so many folks fail to do thus struggling with the fun and accuracy down range be it a animal or hard target.
Also do yourself a Hugh favor and calibrate your scope prior to mounting it on a rifle. This involves checking the travel within your turret travel on a 72″ ruler at a measured 100 yards with a tape not a range finder – from the ruler to the center point of your scope and recording the actual trave of the reticule as you dial the turret then you can enter the offset in your ballistics program. It doesn’t matter what scope it is we test every scope prior to mounting be it a Schmidt & Bender, Vortex, Night Force, Bushnell or Leupold – they all will have an offset some will be close some need a bunch of correction.
If you ever want help or have questions on this test please ask.
I know Randy will have a good amount of info to add as well.
Good luck

What part of the country are you from and what level of experience do you have reloading? If your new at it thats not a problem if you’re anywhere close to WI. you’re more then welcome to spend a day learning some hands on with reloading.
Cheers
JH
If it fits your budget you could always get the 300 you want and suppress it, then you would have recoil and noise control making it easier on the shooter.

A little fun with fire forming brass.
21 grains of Clays shotgun powder
94.5 grains of Quakers Grits
And a little tissue paper packed in the neck area
Like shooting blanks
From left to Right
Finished round, New fire formed brass, original brass

Just a fun all around shooter

A fire control system with drag in it could be causing inconsistent fire pin strikes,if the primers are set too deep in some cases and flush in others the deep ones could be fliers. Pull the bolt apart and give it a good cleaning.
Also the amount of pressure applied when setting the rifle into your shoulder will promote a vertical impact string – if you setup tight and give your rifle a lot of lovin the impact will be low. If you get into your rifle with very little pressure into the shoulder you will throw one high from the group.
Another common cause is over aiming, this happens to all levels in the shooting community, folks trying to shoot a tight group, trying for a perfect one hole bullet group and working through load development where every shot is the upmost important round. Folks will over aim, first off if you sence at any point that the shot is not going off – back out of it. If you force it you may get lucky but more then likely you will throw it.
Maybe some of this will help

The 67s did not have side marker lights but in 1969 as far as I know all Camaro and Corvette’s had side markers, I think a law was passed making it standard equipment. My best friends Camaro is sweet ride when it comes out, no lack of power either.
I sure am sitting on a lot of test loads waiting for a day away from work with fair conditions.
I have a bunch of 69 gr. Noslers custom comps loaded up with Varget and H335 about 7 load weights in each to test – just trying to get the 18″- 8 twist with the Wylde chamber to shoot very well with a bullet in the 65 to 69 gr. range for the 223.
I have had great luck working with a 338LM bullet doing RnD we have been pushing the 300 gr. Scenars at 2750 fps with excellent results for years – around 2800 rounds down the tube. we have been using a stepped G1 BC. calculated at.
.785 to a min. velocity of 2720fps
.760 to a min. velocity of 1970fps
.730 to a min. velocity of 1250fps
.720 to a min. velocity of 980fps
.740 to a min velocity of 0 fps
Lately we have been working with a hybrid bore rider with some excellent results. A 256 gr. bullet with a G1 BC of .814 ,yes that is correct a lighter bullet then the 300 grain Scenar with a BC of .785
The bore rider weighs in at 256 grains and carries the high BC of .814 and we are pushing this bullet at a screamin 3138 fps with ease.
Not a bullet you would use for everyday plinking at steel, but when you want to hit something this little hot rod shines when it comes to minimum windage and dialing your vertical.
If you look at the earlier pictures you will see the long sharp profile of the 256 gr hybrid in the center with the 300 gr Scenar to it’s left.
This last weekend we did some quick RnD with the GS 414 grain bullet used in the 375 VM2 but this time we ran a few test loads out of the 375 Snipe Tac, at 133 grains of H50BMG. We had the 414 grain bullet running at 2784 fps the load had a extreme spread in volocity of 6 fps and on two separate days yielded a 1/4 to a 1/3 min. of vertical at 600 yards this was all accomplished within 13 rounds total from start of load development to last test round on second day. We have some additional loads ramped up higher now to see if we can slip into another accuracy node with a little more speed, our goal with the 414 grain bullet out of the Snipe Tac is 2900-2950 if it’s less but accurate thats good as well.
I have a bunch of test loads seated at 2305 giving it a jump of 25 thou. to the lands in the 260, the rifle still shoots well with 2800 plus rounds and from day one has consumed H4350 and the 139 gr. Scenars. So I have some test loads at 42.4, 42.6 and 42.8 just to see if the sweet spot has changed any. The most important thing I do is record what the bullet is to the lands and where it likes to run when new, then as time goes by and every 1000 rounds later you can re-measure and push the bullet out to get it back into the sweet spot. If I remmember correctly I am at about 38 thou. of throat erosion now, I will run this until I see a sudden drop in speed then the barrel is done.
We have another 260 to fine tune and the new 6.5×47 that we just chambered to do load development on.
So there is some more test bench news take care.

Here you go a few more, my shooting partners stress reliever.

Not sure why two pics of the 338LM with a 300 Scenar, a test Hybrid and the 375VM2 with the 414 doubled up.
Nice

Did you have a chance to search a little on the cheek weld pad from McRees Precision? Probably the the most solid comfortable and functional pad we have seen.
Not sure on the travel time but we can get together and send a few.
JH
Dang now I’m going to have to do this someday.
“Grouse”
Now what that means out in the dog town at 95 degrees with a variable wind blowing, heat mirage, moving dogs, bugs landing on my face, sweat running in your eyes, an imperfect field rest, etc is that the ammo is now one of the lower factors on the totem pole for me.
Dam, that really gets me all warm and excited, never had the chance to experience a dog town sit down yet. Thanks for throwing it out there the way you did, makes one want to try it.
JH
It’s all the little things that one can clean up that pay off when under pressure.
Randy
You can always take the Cheek Weld pad for a test drive to see how it works for ya before you order. We always have ammo available, beware the recoil or the lack of it is addictive.
