[QUOTE="dok7mm, post: 1092817, member: 90080"] In my previous post, I failed to catch your OAL limitation. I was lucky enough to start .010" off lands and lucky enough for it to shine with 3 rifles [ same contours and lengths helped]. Would like to note the 140 bergers didn't impress at 1-200 yds. It was only when I shot initial ladder @ 300 yds, I saw a tight vertical in the 51.6 gr. & 51.9 loads of H-4831. Next, loaded 5 each from 51 to 52.2 for 400 yd. ladder. Once again, the 51.6 & 51.9 shined [ 3/8" &1/4" vert.] Pretty much the same regime for all three. I have had your problems with a long throat 7Mag and it was frustrating to try all those different seating depths. My best advise [taken w/gr. of salt] would be to try a bullet that takes a jump better [maybe an AMAX] or go with H-4831 or H-4350. One last thought- try 210 M primer. In a short fat case, I don't see the need for mag primer. You should get better SD with large rifle primer, therefore smaller group. JMO Good Luck. [/QUOTE]
