OP Dusty246 Campfire Regular D Joined: Sep 2010 Posts: 1,706 NJ	Have some 105s on the way for my Stevens 200 243 w/1-9 1/4" twist which Hornady recommends. I have the 85 gr. Partitions shooting fine with H4350 but want a bullet for a windy Montana antelope hunt. I'm sure I'll need a slow powder and have RL 22 and 4831 on hand. Any ideas?

And worked my way up to 48.5gr. In .5gr steps. At 350 yards 46.5gr to 48.5 showed only 2" of vertical. Where .5gr difference was jumping around 4" on loads below 46gr. I just loaded up 16 more in .2gr steps so another trip to the range is in order. I still need to pick up a chrono but the speed seems to be there. Max load of 780 was hitting quite a bit higher than Nosler's factory 85gr. Partition load at a stated 3250 fps.

I think it would be a super load to let him stretch it out some and probably shoot just as well as the 7mm Mag's.. I have seen the 105AM shoot some incredible groups at 600. Semper Fi
