I don't see the advantage
In my 22-250AI with "8" twist the Sierra book says I can get 3,300 with 80 gr bullet. I was loading 39grs of H4350 and getting 3,450 with 75gr A-max. Now you say out of a 8" twist BBL you can shoot a 90 gr bullet? I thought that bullet requires a 7" twist? Were those 90 gr Berger bullets?
How does it profit a man if he gains the whole world but loses his soul?
