[QUOTE="orch, post: 641344, member: 35688"] Hey there... As I just posted on Green 788's thread in next folder down from "reloading"... I'm am shooting almost an identicle load to his with retumbo and 300 gr sierras and am very happy with it.... One thing I would check is your case neck run out... I was going along good when I started load development with mine then things went to crap on my 3rd loading of my Lapua brass.... Turns out I had a bent decapping pin in my standard RCBS dies that was giving me real bad case neck and bullet runout and was sending fliers all over the place... Bought some redding competition bushing dies and that brought every thing back down to nice tight groups.... I usually anneal my cases every 3 or 4 loading cycles (about when I can feel the neck tension start to increase on resizing and bullet seating... Don't ask me how I can tell, but it just feels like the brass is resisting both oporations more, I anneal and it goes back to normal....) Oh I have also tinkered with the 285 hpbt's and retumbo and had a potentially good load but kinda quit it cause the 300 SMK's were shooting so well I felt the time and powder involved in developing it wasn't worth it for me... I have the load info around here somewhere... If I can find it I'll post it for you... Found it: 285 gr hornady hpbt match 91.4 gr retumbo 2822fps (couldn't find the oal but it seems I remember i had it set so it was the same distance from the lands as my 300 gr SMK load) Also tried a box of 300gr Bergers but they preferred being seated out close to the lands in my gun and that put them way over my overall mag length so it was a deal breaker for me...
