I know that I am way behind the curve here but however we cut it I need to ask a few questions regarding smokeless reloading. I recently picked up a Win. 1886 in 45-70. I plan on getting involved in the lever gun silhouette matches. I went to my loading bench and also to the internet and decided on a powder (IMR4759) which I have a pound of. Naturally as I read and searched further I find that it is no longer being produced.
I know that Reloader 7, 3031, 5744 and others can be used in big cases like the 45-70. In an effort to keep the pain of buying several and trying them each I am asking for recommendations from shooters who have already gone that route and done the leg work. I'm not lazy but then too I don't need to reinvent the wheel.
I shooting a 405 grain flat nosed bullet and the distances are from 50 yards to 200 yards. The gun, of course , is the Win. 1886 in 45-70. I would prefer a powder that substantially fills the case like 4759 did.
Any recommendations on a smokeless powder, clean burning, consistent, in velocities between 1200 and 1600 FPS?
