I've generally heard that CCI and Winchester preliminaries have hard cups
I use TAC as essential powder in .223, a decent all around choice for 6.5 Grendel and have recently begun working with it with 155's in .308, with empowering results. Continuously use charges as tossed from a BR30 measure, which subsequent to unloading around 20 turns of the handle, yield incredibly low weight variety of 10 tossed charges tac powder for sale . Had never heard this, however in perusing a 223 stacking article in Rifle's unique AR stacking release that is simply emerged, was said TAC has a similar enemy of fouling characteristics as CFE223. Can't say certain, yet have excellent outcomes with TAC, in any case. I'd purchase 8#, in the event that I could track down it. I've perused reports that TAC functions admirably in .308. Concerning temp steady, twofold base powders like TAC will generally be more temperature delicate than single base powders (meaning less steady). We as a whole have our number one powders, similarly as we have our #1 slugs.
