I've been meaning to do this for a long time and finally loaded up some ammo to answer my nagging questions. I'm using 13.2 gr. 300 MP with the 40 gr. Nosler Varmageddon at 2926 fps out of a 22" barrel in my 22 Hornet with excellent results. Trying 300MP in my CPC reworked Ruger 77/22 VHZ 22 K-Hornet just seemed like the thing to do. My previous load of choice in this rifle is:
40gr Nosler VG 12.9 W296 Rem 6 1/2 WW 1.800" 3110fps 29 fps SD
So how did 300MP work?
The short answer it works great. High velocities and low SDs.
The 14.0 gr. load punched a nice sub-0.5 MOA group.
40gr Nosler VG 12.9 300MP Fed 100 WW 1.800" 3100fps 3
40gr Nosler VG 13.2 300MP Fed 100 WW 1.800" 3179fps 17
40gr Nosler VG 13.5 300MP Fed 100 WW 1.800" 3231fps 13
40gr Nosler VG 13.8 300MP Fed 100 WW 1.800" 3257fps 11
40gr Nosler VG 14.0 300MP Fed 100 WW 1.800" 3295fps 9
40gr Nosler VG 12.9 W296 Rem 6 1/2 WW 1.800" 3110fps 29 fps SD
