RE: what's your biggest booboo.....be honest?
I usually take 3 or 4 different rifles to the range when working up loads so I can let the barrels completely cood down. Made the mistake of shooting 300 win loads in a 300 wby. Grouped about 3"--recoil was mild and poi was close! Sure felt stupid! Now, I won't take any ammo with me to the range that could be chambered in the wrong gun. I learned long ago that I can't reload with someone else in the room--talking is too much of a distraction, and two sets of eyes are not better than one. My oldest boy is now shooting with me regularly--I do need to figure out how to safely get him involved in reloading as he is interested.
