Rimrock list their hard cast line as either 12 or 15 bhn, I figure either would do for 1100 fps and that should definitely give you a "bigger hammer" .Ordering some 260 gr Keith Style Flat Base from Rim Rock Bullets, and was wondering if anyone has loaded these bullets, or a similiar 260 gr bullet?
I’m loading for a Taurus M-44, and I’m not looking for max loads with H-110, but will be loading with CFE Pistol, and Unique. Don’t think the Taurus is equal in strength to a 29 Smith and certainly nothing like a Redhawk, but would like to work up some loads in the 1100-1150 fps range that won’t put any undue stress on the Taurus .44, so I’d be interested in anyones experience loading this bullet, or for a similiar Taurus .44 Mag. I’m really looking for a bigger hammer than 180’s in my Service Six without having to buy a new revolver!
Even in 4" guns, powders in the 2400 burning rate work, but at 1100 fps even powders down around Unique work well also.
I don't have much experience with .44s using really heavy bullets, but I've shot a few deer with a 245 Keith, one at 110 yards, in .44 Spl. at around 1000 fps - I could not have asked for any better performance (dropped on the spot) - I cannot imagine a 260 doing less, and it should penetrate even better on bigger critters. I did load some 340s over 296 for a 5" Redhawk but never shot anything with the load - and I'd likely consider it a bit too much these days.
Two modern powders that seem to do well are Lil'gun and Longshot (the latter being "faster") but all of the powders I see listed above should do well also.
While I like S&Ws and Rugers I do own a different .44 - it is a 2.75" Astra .44 - it seems to be a decent gun as I suspect your Taurus is.
