17 Fireball and H322

[jwcrabb]

Just curious if anybody uses H322 in the 17 Fireball. I bought some to use in the 17 Remington and ended up using Varget. I would love to use it up on some Prairie Dog ammo. BTW, i'm using the 25g VMAX.

Started using H 322 in my 17 Furball and so far I am liking it a Lot.

What kind of velocity are you getting with 40 and 50 grain bullets using this powder. It is one I have never tried in the 221 so am quite interested as it is easy to come by. Thanks.

40/50 grain bullets in a 17 Fireball ? Really.

Sorry guys, apparently I can't read. The post clearly said 17 FB and I read 221 FB. You are right BW, out of the 17 I use 25 and 30 grain pills. Still haven't used 322 powder in it either, I like Benchmark and 8028 in the 17FB so will be interested to hear how this powder works out for velocity with the 25 and 30 grain bullets.

What I was going to respond till I went back and re-read the original post. Much lighter than 40 would leave the Varmint grenade, which shoots well out of my 221 FB but the batch to batch frangibility is so variable I don't use them any more, and it sure isn't designed for heavier bullets. I use the 40 Vmax and the 50 grain SPSX over Lil'Gun as my two common bullets for the 221.

What are you shooting out of yours?

I use it with 25 gr Bergers in mine. About 3650 fps, not fast but accuracy as good as it gets with a factory rifle (1/2" if the jerk behind the trigger works). Watch pressures near max. I think I was using around 17-18 gr???

17.2 grains of H322 jn my Montana Varminter with a 25 grain Berger yields 3695FPS with a SD of 12.
