Like I said, the Ar 30 that I did the load development for was not mine. If you guys say that it is a 10 twist, then I believe you. I thought I had red somewhere that it was a 12.....my bad.
Now....I know a 10 twist will do great with the 300 SMK. The problem is, after we found the load for it, he bought 500 250 smk's, which we haven't used many of yet. But...he also has a WBY MK 5 in lapua with a 1-12. He still can use them. I will say that I was more than a little surprised at how well that HOMELY thing shot!!! Pretty much everything went into 3/4 inch groups, with the final load coming in at 1/2 inch @ 100 (3 shot). Poor bag gun, cleaned up like a dirty chiminy, but it seemed to shoot!! We were only around 2875 fps if I remember right. But he is having trouble shooting way higher than the ballistic program says, so I might have had chronograph troubles. I think that I needed to punch in about 3050 to make the POI match the computer.
To be honest.....deep down..... in places only I know about....I was/am considering an AR 50 :eek::eek:. Now there's $5000.00 that I'll never get back!!!;)
