Re: reloading info for accuracy
Hello friend, I use a .300 Jarrett for big game. I seat 200 gr. Matchkings into the lands for practice, and have shot many .5 groups a 100yd, but too long for the magazine. For hunting I seat Sierra gamekings as long as possible that will still fit and feed from the magazine. They consistently shoot MOA. In my experience that has been the trade off when using these looong cased magnums. I will carry a few shells seated long if I expect the possibility of a really long shot.
