I'm pretty limited on powders right now, the only powders I can't get around here at the moment is imr 4831, 7828, maybe some rl25 and a guy said he'd sell me some h1000 if I need some. I have a decent load with imr 4831 and the tsx bullets, 68gr set at 3.167 but my groups are spread out with the ttsx bullets.
This is my what I got with 110gr accubond with 69gr of 7828 pushing it
And this is what I have with the 100gr tsx and 68gr of imr 4831 pushing it
My groups with the ttsx have all been in the 1-1/2" to 1-3/4" range.
