When I wrote that the load is reduced to Savage 300 levels, I didn't want to scare you.

My particular load is actually a very mild Savage load at that.
Using 44.4 gr of IMR 4894 with the Sierra bullet MV shows 2600 fps but that is with a 26" barrel. The Rem carbine is 18 1/2 " There has to be a least 200 or less fps in MV from that barrel.
That load also groups well with 150 gr Speer, and Hdy's
As posted above H-4895 can also be reduced to even less MV's then IMR 4895
