Winchester Staball HD Load Data

Last edited:
Nice! Right between 8133 and retumbo on the chart! And it's a high density ball powder!!!!! This could be a very good thing. I can see it being very very useful in the 257 wby shooting 115 grains and up, especially with a fast twist to take the 134 eld m 135 Berger 140 chinchaga and black hole bullets.
It is. Very useful. Running 133 Bergers, 134 Hornadys, and 145gr Black Holes with it in modified .264/.257 Win Mag (called .250 MDC)
 
Did a little testing with Staball hd in the 300 Norma yesterday. Loaded up 1 round of each charge just to try and get a feel for what velocity/pressure signs will be.

Rifle: 300 Norma Magnum, Bat vesper action, 26" Benchmark cf sendero barrel 70 rounds fired

Components: Staball hd, Peterson brass, 245gr berger eol, fed 215m

83 gr- 2750
84 gr- 2788
85 gr- 2830
86 gr- 2851
87 gr- 2890
88 gr- 2934
89 gr- 2960
90 gr- 2987(very faint ejector mark)

No heavy bolt lift, no clickers

The 6 shots from 85-90gr landed in a 1.1 moa group.

Howdy, are the speeds close to the other powders you've tried and what powders have you tried. Thanks

The only other powder ive tried in it is h1000. 84 gr of H1000 was getting me 2970 with the 230 hybrid and good accuracy. Any higher than 84 gr was giving me pressure signs and clickers. I definitely do not think h1000 would give me the same performance as staball hd with the 245. Have not tried N570 and probably won't.

I've also been using it in my 300 win mag with great results shooting 215s. It's extremely similar to Retumbo from what I've seen so far.

Awesome thank you 🙏
 
Picked up 2# of HD in OKC yesterday and not sure what cartridges I'm trying them in as having so many?

Oh no 😮
You mean you traveled through the heavy Oklahoma dust all the way to OKC???
😂
Just kidding.
I am in the same boat, trying to get powder I hope that I can get to work good in one of the larger calibers I load for
