Apr 13, 2022 · About a year ago I was lucky enough to buy a custom Martini Cadet chambered in .256 Win Mag. My first loads were with Sierra 87 gr bullets with IMR4198. The little rifle has a 22" straight, 3/4" dia. barrel & my starter load grouped 1/2"! Yes, I'm excited! Unfortunately I only had a small amount of that powder. I have some H4198 Im going to try ...

Dec 23, 2015 · When I do those I anneal them lightly first, then just form with the 256 Win mag die pretty much skipping over the 30Mauser die. Thing I found out about those is when using 357Mag brass the cases gets about .025-.030 under spec length. If you use 360DW brass a person would be much better off, everything is the same except it has a beefier web.

Jul 5, 2023 · I went to a garage sale & I bought a box of handloaded .256 Win Mag. I won't shoot someone else's garage sale reloads, but the factory Win brass alone was worth the price I paid! Scribbled on the box was 75gr H & 4.9gr of TiteGroup. I looked around in my manuals & I couldn't find any data for TiteGroup in the .256. Curiosity has the best of me.
