I was wondering what people are useing for powder for the 243AI with the 107MK's and 107BergerVLDs. I was thinking H4350 or H4831

Jared, those powders are too fast. Try something with a slower burn rate and you can pick up 100 to 200 fps. images/icons/wink.gif

H4831SC is a bit to fast to get the velocity im looking for. I would look towards RL-25 or N170 If using RL-25 try to get a lot that was made this year.
This lot of RL-25 is a bit slow than the last lot that I had. The last lot was a bit temperature sensitive which it was an older lot. The lot im working with now was made this year. 1/9/03

N170 looks promising but the RL-25 has been my favorite. below is my favorite load.
