Barry,
Your comments on current lots of IMR 4227 is interesting, altho I can't really complain about what I'm getting with my lot of it. with your comments in mind I guess I better test that new can I bought yesterday. I got caught once not testing a new lot of .22 ammo and lost a match because of it. But had always thought that smokeless powders that are sold over the counter are blended so as to maintain a consistent lot to lot performance. Your comments???
Also your comment on humidity possibly affecting the formation and hardness of the fouling ring is well taken in my opinion. I keep track of temp. & humidity during a shooting session, so it might be possible to find some break points that could be useful.
Sifting powder!?!?!? Now this is something I've heard, and done, with black powder, but didn't know it was something that would benefit smokeless. Considering how fine H110 & H108 are I'm not sure how this would be done. Can you give us a rundown on what you do?
Dale53,
Have a source for 8 lbs of H110. Might have to try that when I get the chance.
40_Rod,
AA#9 is in the works for a tryout as is SR 4759. I have used it in the past in an 8.15 x 46R but didn't have much success with it. Probably due to the rough bore it would foul up at the most inopportune times, so I switched to 4227, which worked better. As long as it didn't foul out I thought it gave better accuracy than 4227.
The reason for asking about H110 was because I'd never used it and was kind of at a loss as to where to start. So, speaking of that, where do you think a good start point would be for AA#9??
