New Winchester STA-Ball HC

[Still Unbroken]

Ratumbo powder is getting impossible to find, the Winchester sta-ball HC has the same burn rate and make a great powder for
Heavy bullets.

Accurate MAGPRO is often overlooked. No difference in velocity compared to Retumbo when comparing at the same pressure levels.

Several Hodgdon powders, sourced from ADI, are impossible to find. H4198 being, to me, the most conspicuous, but I'm a target shooter. I sure wish IMR would re-do their 4198 to smaller grains and a tad slower.

Magpro works good in a bunch of calibers and meters great.

Works great in my 243win and 105 gr bullets. I get 3,087 fps from a 26" barrel and quite below max load because I went up to around 3,200 fps and saw no pressure signs. Winchester Brass and 210m primers.

Also works awesome in my 300 WinMags.. 210 SMK @ 2,952 fps from a 26" barrel.. I think I saw some pessure marks (ejector imprint on a few pieces of brass) around the 3,100+ fps. F.C. brass, 215M primers.
