The 75 A-max go mint in my 22-Terminators at 3200 fps, rechambered 1-8 T3 223, generally sub 0.5 moa
So do the 53 V-max at 3700fps.
Both shot better in 1-8 than 1-12 when I did initial testing in 223.
I didn't expect the 75s to go in the 1-12 but was supprised when the 53s went better.
I find either 2206h or 2208 go well with the heavy projectiles, the case gets pretty full.
