Actually my rifle is a Contender carbine, Bullberry 16 1/2" barrel. With that combo I will get 3250 fps with a max load and a 40 Vmax. Deadly combination on pds to way out there.
I've had mine 10 " contender for about 30 years. Started out using imr 4227 ,tried a lot of other powders , but still use the imr , just like the way it shoots.
