Home Forums Reloading Varmint Rifles Rimfire Alternative: Part Deux

Shot three 4-shot groups @ 50 yards this morning. I tried it in three different brands of brass, just to see if there was a preference.

Ruger M77 Hawkeye w/ 22" barrel
55 grain Hornady SP w/cann #2266
CCI 400 primers
12.5g IMR 4198
COAL 2.190" (0.011" off the lands in my rifle)

First up, FC brass (0.754" 4-shot group @ 50y)

V1 = 2,011 fps
V2 = 2,053 fps
V3 = 2,059 fps
V4 = 2,084 fps

Average velocity was 2,052 fps with a s.d. of 30.29 fps.

Next up, LC 14 brass (1.035" 4-shot group @ 50y)

(Chronograph failed to read all 4 shots)

Finally, R-P brass (0.781" 4-shot group @ 50y)

V1 = 2,008 fps
V2 = 2,023 fps
V3 = 2,019 fps
V4 = 1,978 fps

Average velocity was 2,007 fps with a s.d. of 20.34 fps.

I'm not sure about the double grouping. Perhaps a COAL adjustment may cure that? Not quite the same accuracy you are getting with the 50g V-MAX but the only other time I've tried this bullet it didn't group well at 100 yards (1.93"-2.85" 4-shot groups). So I'd say it did pretty darn well at 50 yards with a "bunny load".

These loads were a blast to shoot and make plinking darn cheap. I'm definitely going to play with this more, but I'm glad for this discussion.

Great load Seafire. And thanks for the thread, ingwe.
