Glad you had some success both at the bench and then at the range.
IME, it’s rare for the max load to work out to be the most accurate, but as you’ve found out, it can happen. I don’t know how hard the .25-06 is on brass as far as stretching the cases, but you’ll want to measure your spent brass to make sure the overall case length doesn’t go beyond the max.
As others have said, work slowly, be careful, and inspect every round at every stage in the process. If you reload long enough, you WILL have those “Wow, glad I didn’t fire THAT round,” moments. Just this winter I was getting my .243 brass cleaned and resized and in 100 rounds I found not just one, but two cases with cracked necks. It does happen.
Also, when charging the cases with powder, visually inspect EVERY case before you seat bullets. I charge all my cases with powder at once and place each one in a block, then use a flashlight and look down into each case to make sure powder is in each case. Whatever your system is, check each one to make absolutely sure it has powder in it before you seat a bullet.
The danger is having a case get by you with little or now powder in it. Then shooting that case and having the bullet lodge in the barrel. Firing another cartridge without checking the barrel would obviously be a very bad situation.
Handloading is a terrific way to get more out of your rifles. I have yet to meet the rifle whose accuracy could not be improved by feeding it gourmet fodder from my own handloading kitchen.
