Re: 22-250 Ackley Improved - 1:9 twist - 30\"
Thanks for that information. I am hoping to get a bit more velocity - with accuracy. Accuracy always has the nod. My goal for target work is to be able to shoot along with or close to a 6.5x284 - 140 gr out to 1000 yds.
From the ballistics tables, it appears that with the 75 A-max, 3200 FPS is nearly identical in wind drift, which is the key for target work - as long as the accuracy is there.
Regarding powder. My thought it to start with what I have AA4350, H4831 for the slower burning and Varget or perhaps RL-15 for the faster. Any thoughts?
