.41 magnum with Rimrock 240 gr Keith SWC FB

[lobo]

Hello. Looking to see if anyone has any load data for .41 magnum with Rimrock's 240 gr Keith SWC FB. Thanks.

I use a cast 240 keith in my 41 magnum. It is not the rimrock however.
My load is 21 gr H110, WLP, in starline brass. Gun is a Ruger Super Blackhawk Hunter. This is max in my gun.

Dunno how I didn't see this before. I really like that bullet.

All warnings/caveats apply, can only vouch for safety in my guns, etc.

New Starline brass, CCI 300 primers & 1.673" COAL with a firm roll crimp & cheap Chrony Alpha (45*F, partly cloudy)

9.2gr Unique averaged 1117fps from my 5.5" 'Acusport' Bisley & 1170fps from my BisHunter.
16.2gr 2400 averaged 1198fps from the 5.5"er & 1267fps from the BisHunter.

In both cases, there were no pressure signs, with 'fall out the chamber' easy extraction & mildly sooty cases.

Both guns are 'shooters' in general, but they seem to really like this particular bullet. The Unique load is so soft shooting & accurate that I'm not interested in tweaking that load at all. I'm going to walk the 2400 load up to 16.5, 16.7 & maybe 17gr just out of curiosity, but it is very accurate as is. I will most likely dedicate the 5.5"er to the Unique load & reserve the Hunter for the hotter loads.

Took a cow elk a few years back with my Accusport bisley 5.5" 41 using 9.2 grs of Unique & a 250 gr LBT WFN, this load was fine in my gun, work up in yours. I also use the 17 grs of 2400 with the same 250 gr LBT bullet. Again, work up to this load in your gun a always.

When I started reloading, an old greybeard recommended Unique & 2400 for the .41 & cast boolitz. I don't have the vast experience that some of y'all do, but I've seen absolutely no reason to deviate from that.
