22 BRA Primer testing 300 yards

[JamesnTN]

well at 35* this morning I did the primer test on my new 22 BRA barrel. Results were more promising and the next testing will be at 500 yards.
One nice thing about using H4350 is in the 30* temp spread from yesterday to today there was only 6fps loss in velocity.
Powder used is H4350 Sierra 80 grain moly coated seated at .008 off the lands.
Accuracy node for these bullets seems to be between 3180-3200 FPS




33.8 grains



34.0 grains

This is somewhat close to what I was thinking was going to be the results. Looks like a good node there with the 450’s.

My last 221 Fireball shot well with a lot of different primers but really came to life with the 450 Mag primers.

Best of luck with your testing.

Looks like a "keeper" James, great steering also...

Thanks Paul
If wind plays nice in the morning I’m going to stretch it to 500 shooting 33.7 33.9 and 34.1 and see how that goes.
