While hunting with my buddy this week, he showed me his backup rifle, a 300 Winchester (Tikka). He showed me his ammo which loaded for him by some 80-year-old guy he knows. The box had printed on it :
67.5 grains IMR 4350
208 grain AMAX, 3025 fps
The barrel looks like a standard 24" barrel with a brake added on
I find it hard to believe he can get this velocity out of a 300 Winchester, 208 and especially using a powder as fast as 4350.
Anybody have any thoughts on this load? I want to chronograph it for him but not if it is so hot it is bordering on unsafe!
Seems like H1000 and the likes would be much better powder choice for this bullet.
