i can’t speak to speeds as I don’t own one yet, but if you wanted 50-100 fps over a prc I personally would just do a 30 nosler instead of dealing with fire forming brass and custom dies.
I really don't have a valid answer except that i'm a stickler for maximizing efficiency. I also don't mind fire forming or custom dies. Especially since i can fireform with Hornady ammo. I was just looking at the 225gr ELD-M @ 2900 vs my current 7 SS load of the 180gr ELD-M @ 2900 and was pretty shocked to see it on the heels of the 225gr. Guess i could go that route wonder how the long 225~250s would fair with the 30 nosler.
