2″ groups at 50 yards indoors, 50 yrd shots don’t happen in the woods with the trees movin’ and the wind blowin’. Thats when it counts. Good luck

The last kiddo I knew that shot that well was from Chatfield. Probably not that good though. There is no excuses for you not to tag a big ole buck now.

Heck I would be happy for 4″ groups at 50 yards outdoors.

Heck I would be happy for 5″ groups at 50 yards outdoors.

Alot of people would be Ripper. 2″ groups @ 50 yards , he should be shooting somewhere(espn) other then the local leagues.

coyote, what I agree with, is, if you shoot a 2″ group at 20 yards, with a pin, and can shoot 4″ groups at 40 yards and are happy, then you could probably say you use the same pin. That a bow would shoot the same group at 20 and 40 yards, is highly unlikely, the 20 yard would be in the upper part of 4″ circle, while the 40 yard would be in the bottom portion of a 4″ circle. A 2″ group at 50 yards, consistently, would have to be no wind, probably indoors, tons of practice, and the Olympics would be calling.

I think I’m throwing the bs flag

I think I’m throwing the bs flag

what is bs ? if you have a 20 yard pin, and shoot 2 in groups, could you not shoot a group 4 inches below that at 40 yards ? If you cannot, then you probably are hunting with an illegal bow (less than 40 lbs). I have no problem shooting a group at twenty yards, in a 2″ group, and shooting another group at 40 yards, maybe 4″ below that at 40 yards with the same pin. Whats your logic ? If you would like to see this, I welcome you to watch.

Alright guys. I am not taking any sides on the issue, but the engineer in me got the best of me. Here are the calculations of the arrow flight. Here are my assumptions:

I have assumed no losses due to air friction.
I have used the IBO FPS of 315 fps (Switchback XT)
I have assumed a 29″ arrow @ 8.2 grains/inch using 100 grain Thunderhead broadheads.

The result of the calculations are as follows.

The arrow will travel from the 20 yard target, to the 40 yard target in 0.19 seconds. Assuming the bow is sighted in at 20 yards, the drop of the arrow will be 6.97 inches at 40 yards. The resultant kinetic energy is 74.4 ft-lbf.

The overall weight of the arrow effects the top end velocity, therefor effecting the drop as well as kinetic energy. Hope this helps. Fun discussion.

And all of this from a simple duck hunter.

Mallard, bravo !!! What your calculations do not take into account, is the individual trajectory of a given bow. If in fact, all bows were flat shooters, this would work for all scenarios. However, bows that are tuned differently, will change the trajectory. If you draw an arched line, and lay a straight line over it, it will intersect at the close end, and the long end. In theory then, the spots where the straight line intersects, will have the same point of impact, at different lengths. I just know my bow, a Hoyt V-tec, set up to 68 lbs, drops about 4 inches, from my 20 yard pin, to 40 yard pin. I am not trying to say I am right, just that it is possible to have the same pin for 20 as 40, it depends on your set up. It also takes into account, what is “good enough” for each individual archer. Groups at 40 yards that are 4″ low, might be acceptable for some guys, and not others. I personaaly have a 20, 40 & 50 yard pin, though I rarely even practice the 50 yard pin, as I would not take that shot typically, where I hunt.

Big G,

I am honestly a one pin guy myself. You said it well when it is good enough at 40 yards. I figure if I can stick my arrows into an appetizer size paper plate at 40, I am good. I know the vital zone is larger than that.

Now speaking of trajectory. The calculations are based off of a bow that is “zeroed” at 20 yards. The end all trajectory is only a function of your arrow speed. The heavier arrow will result in slower speeds which results in a higher initial trajectory. That is why I wanted to point out the velocity of 315 fps, and an arrow that is zeroed at 20 yards. At 20 yards, the angular trajectory is zero with respect to the shooters position. Regardless of the bow you guys are shooting, it comes down the arrow speed. That is why to get an accurate measurement of drop, your bows need to be chronographed with the arrows and broadheads in which are used. When the bow is chronographed and the overall weight of the arrow is measured, only then can a hunter know the true energy of his/her equipment. I would be happy to figure this out for anyone if iterested.

The one major factor that the calculations do not take into consideration is the lift that is created by the arrow flectching, as well as the broadhead blades. I don’t really feel like trying to figure that out.

All in all, I shot a 74 lb bow with one pin set at 20 yards. I always felt comfortable putting one in the vital zone up to 35 yards. This was as long as I was practicing consistently. I am far from a tournament shooter so +/- 1″ does not mean much to me.

Settle down there big G. I wasn’t even responding to you. I was responding to the 2″ groups at 50 yards.
As far as all the stuff you are writing about, whatever. I could care less what you do or think or shoot or group. I’m sure you can do anything you say. So settle down.

Mallard, exactly. That is what I have been saying since my 1st post. One guy might be happy with 4 inches of drop at 40 yards. I used to be a one pin guy myself, although it was a 30 yarder. I used to shoot a slower bow too.

Thanks for clearing that up. I guess the fact that you replied to my message, I thought you were talking to me. I personally don’t buy 2″ groups at 50 consistently myself, but I don’t know, so I will refrain. I am not wound up, just saying what’s good for one, may not be good for you. I’m sorry I bothered typing what I do with my set-up.

I shoot alot. Always have. When I go to Canada etc. I will practice out to 70+ yards only to make me much more comfortable at 50 yards.
I shoot one adjustable pin. I have marks for 20 yards of course, 30, and 40 yards. The one adjustable pin has advantages over multiple pins and the multiple pin has advantages over the single adjustable pin. On fixed pin seems a little risky to me. Sounds like a guessing game.

I am okay. Think I’ve got away from the original post a little. I too love my Carbons. Just picked up a 1/2 dozen Maxima’s last week. They are beautiful. Run your hand the whole length, the shaft wrap is perfect. Smooth as silk. My Carbon Express 300’s have ridges the whole way. They seem rough as a corn cob next to the Maxima’s.
