Re: unique powder
I shoot 158gn RNFP thru my Winchester with 3.1 grains of N310 but that is for 25m. Work quite well but never loaded for longer ranges.
It's not the pace of life that concerns me, it's the sudden stop at the end!

Re: unique powder
The rifling twist is 1 in 30 I believe and loads that work in a Winchester and a Marlin might not succeed in the Rossi
