Hey guys, I sure hope you don't mind my continuous question asking routine! I sure do thank you all for the past help! I am working up a deer hunting load for my 25-06 and narrowed down the bullets to the Nosler 117Gr Partition. Now, I have always used IMR-4831 in the past on Varmit type loads (75gr bullets) with great success. I of course started with IMR-4831 and had 8"+ groups at 100Yds. Now, before you say I am a poor shot, the same day, same rifle, same bench rest, shot a few 3/4" groups with the 75 gr sierra varmit rds as mentioned earlier. I went home and started loading other test loads with different powder, and finally got the 117Gr PTN to group at 3/4" using IMR 3031. This is fine for deer hunting, but I got to thiking it might be able to be better, maybe not. According to the info I have, IMR-3031 is burns much faster than 4831, which is one of the slowest IMR powders. Now I always thought that heavier bullets wanted slower burning powder. Can you guys shed some light on this. And if this is the case, would say IMR-4227 or IMR-4198 group even better. Would it be worth trying some of the other brands of powders. I don't want to stock ever powder made, but any ideas would be great. FWI my 25-06 is Remington 700 THANKS!!!
