Small pistol primers in 454Casull case, 45Colt loads

[mrawesome22-250]

Bought a Marlin 1894CB in 45Colt last year. I had a huge supply of 454Casull brass, but no longer own a 454Casull so I trimmed them all to 45Colt length and use them in the 1894 to great satisfaction. 13gr HS-6 and a CCI small rifle primer under any 250-255gr bullet is crazy accurate. Thanks John Linebaugh.

Anyhow, my small rifle primer and HS-6 supply is running low but I have a huge amount of CCI small pistol primers and a pound of True Blue sitting here. True Blue has almost the same burn speed of HS-6 but according to the manufacturer is very easy to ignite. No coatings whatsoever. A true, unaltered ball powder.

So I'm thinking of testing some True Blue loads ranging from 12-14gr, with CCI small pistol primers in 454Casull cases that have been trimmed down to 45Colt length. Anyone see any blaring cause for concern here? Thanks.

I must be missing something. Why are you thanking John Linebaugh?

His HS-6 recommendation is spot on.

I don't see any problem with that combination. Load a few and give them a try.

Hope this helps.

Ah. I guess I'd just never really considered someone who designed the .475 and .500 Linebaugh cartridges would have much notable interest in load workup for the .45 Colt. Though I suppose many big bore revolver guys probably tinker with that classic cartridge.

Linebaugh has extensive writings out there about a great number of rounds.

Like most famous wheelgunners, he’s experienced in his craft, not just in one tiny corner of the world - his cartridge designs.

https://www.johnlinebaughcustomsixguns.com/writings Lots of great info here. If you go to the very bottom of the page there's an update where he shows the loads he has settled on over the years. He claims that 13gr HS-S with a 260gr cast gives good accuracy in a variety of guns and I have found that to be very true. It is not a super hot load but packs a satisfying thump and is extremely accurate. This load gives 1320fps out of my 1894 20" and puts deer down with authority.

True Blue and standard small pistol primers works very well in .41 Mag cases

Oh, almost forgot. 255ish Gr lead SWC and True Blue in .45 Colt.

Chrono at 5 yards, target at 7 yards. WLP primer though, being large primer brass.


I also have a good True Blue load (Slower-Avg 700 FPS) with an X-Treme 255 Gr bullet.

 

[mrawesome22-250]

Thanks for the info and pics Walkalong. The bullet I'll be testing is a 255gr RNFP from gtbullets. Hopefully this True Blue and standard small pistol primers will be a winning combo.

Edit: From what I've been reading it seems True Blue usually puts up very good ES's and SD's. Seems your load shows the same.

Yes, most of the time it gives low ES & SD numbers, as well as being less position sensitive than most pistol powders.
