Mine is on a Stiller Action. 140 Bergers at 3300fps. I have shot 1" groups at 400 yards.



Is this with home grown load data, or has it been pressure tested?
Is there free-bore?
What is the actual physical drop at 400 yards?
Have you tested out farther?

Reason for questions, I purchased vanguard 257 W, to build this cat on years ago. Never shoot the donor�. It is nice to see the real world numbers.
Thanks..





Tim McWhorter's eliminates the free bore. No idea on actual drop but can easily be figured with JBM calculations. Moderate helping of RL 19 produced that velocity. No pressure signs. I killed a deer at 650 with mine this year. Still has 1000ft. lbs of energy at 1000 yards.
