[QUOTE="Steve Shelp, post: 20906, member: 22"] Brett, I've been away from this site for awhile and I see alot has gone on. Been very busy but your post is right up my alley. Darryl, is correct for hunting loads for that rifle. For all out accuracy in the "6.5" as most of the old-timers refered to the 6.5-300 many years back I've found no better than IMR7828. But you have to slow it down between 3200 and 3300fps for that. But for hunting loads we always used H870 for the extra velocity and decent accuracy. I never used the surplus powders Darryl mentioned above though so I can't give you any personal experience with it. I've got to agree with the other numbers given though. As for the 8" twist if you do use the 155gr bullets you will need it. I've shot them through a 9" and no go. but Iwould stay with the 140's anyway seeing how your rifle is already troated for them. Plus the Sierra 142gr isn't but a couple of points of the BC of the 155 anyway. Let us know if you need any other help. Steve The 139gr bullets, and you also mentioned steel jackets..... has to be the old Norma 512 or 513 bullets which were 139gr bullets. Still have some around here myself. We use to cut the nose some on a lathe to help the bullet open up. Then started using Sierra MK and never looked back. Have fun with your new toys. Mine needs a new barrel. [/QUOTE]
