It won’t get suppressed anyway. Leaving it as it is. I’ll use ear plugs or muffs when using full power ammunition.

I have used Robs casts in 308 and 30-30 both subs and at 1600 fps for 3 years now. Shot reds with the faster load out out to 150yds, worked just as well as a jacketed projectile. Try pushing them a bit faster, gives more margin for error. Should still work with the opens.

What powder and weight are you using for 1600fps in the .308?

I am not sure of the velocity but I get good accuracy with 25.00 grains of 2206H start to get lead fouling at 35.00 grains around 2100fps in my rifles 30" barrel.
