They are supposed to be sending me a few bullets to try out compliments of barnes, this was almost 2 weeks ago and I have not yet received them. Im hoping they show up this week.
Elevation, and barometer seem to be the deciding factors.
I am at 6000' plus. I can stabilize the 53gr v-max [.829 long] no problem from a -14 twist at 3750fps plus, but guys lower in elevation, and subsequent higher mercury on the barometer have trouble stabilizing or can't stabilize at all. I am on the ragged edge according to the SG numbers, but it works for me.
The Barnes 53gr TSX is .792 long, so if you can push it to 3750-3800fps, I think it will go to sleep and fly.
