Re: 338 lm loads
Wasp, it depends on your barrel. I foul mine and shoot the "Star Trek method " Captain Ive given her all she can take" and then clean. But for testing give em all the same treatment just like you would encounter in actual hunting! - 300 yds is a good testing distance for the long bullets, much shorter than that and you wont be getting a good inherent accuracy appraisal and much longer than that and the wind can make a guy scratch his head too much. Get an extra large target and shoot for group size including the flyer or flyers, as long as you are on paper don't adjust the scope ( shoot me now adjust me later). Its all about bringing your maximum group size down even at the expense of opening up the tight group cluster and then its just you and the wind! an interesting point to consider is if in a hunting situation are you going to have enough time to let the barrel cool down between shots, for me machine gun intervals are closer to the truth than cooling intervals. unfortunately if I havent bowled it over by the third shot there isn't going to be enough bullets in the western hemisphere for me to make a good connection.
