That's crazy…but I believe it. I got a Barnes 120 tac tx up to 4060 fps in my 300 win mag. 26 inch barrel. Superformance powder. So 98 grains at 3915 sounds perfectly doable.

That Barnes at warp took two deer last year. One of them had an exit wound larger than my fist. I don't have small hands haha. But it only manages 1.5-2 inch groups. So for light and fast that's more what this 257 is designed for. Accuracy wise my 300 really just prefers 200gr and up it seems.

I prefer RL26 it's given me the best speeds and great accuracy.

I bought an 8 pounder when I got the chance and I use it sparingly.

I also have a 257 Vanguard. Tried many powders. With 120 gr bullets the best powder for velocity in mine was RL-33. Taking accuracy and velocity into account it was RL-22. JME
