Smokeless in a Rolling Block Pistol?

[tactical870]

Anyone here ever shoot smokeless in a Remington Rolling block pistol? I'm particularly interested in finding an accurate, safe load for a 50/70 chambered 1871. Thanks

YES but not in a 50/70 Dingisized one LOL When I get home I will look it up as they were loading factory smokeless for the 1871 but not the 67.

You caught me. It got here today and I've been fondling it inappropriately ever since....

Congrats! Pics please.
and yes I have (Trail Boss )
but I find BP more satisfying. Sort of a Booom and push as appossed to a Baang and snap.
Either way they're a blast.

 

[tactical870]

How many grains BP and with what bullet? As this one's got a nice new bore I'm gonna try some sabot loads out of it. I'm figuring about 30 gr FFG with a 300 gr SST in a hornady black sabot....

 

[DEZ]

My book lists 7gr's Unique and a 265 gr bullet in the original length cartridge

I haven't seen a good mold for a 50 cal bullet in under 390gr. I figured saboted 240 or 300 gr were the lightest thing I had on hand to try in this. I'd actually prefer a good jacketed 50 cal HP if there is anything comercially available.

 

[Pete04]

50 Remington (M71 Army) standard load 25 grains FFg
300 grain lead bullet
Cartridges of the world 8th edition
seemed to work fine for me.

do these old rolling block pistols shoot a shortened version of the 50-70 ? What is the case length of these cases?

 

[Andy]

For 425gr to 515gr (cast - what else?) bullet:

Trail Boss - 7.0-9.0 grs
Unique - 9.0-12.0 grs
SR-4759 - 22.0-25.0 grs
IMR-4198 - 24.0-27.0 grs

All loads are under 18K CUP.

 

[tactical870]

Anyone have a source for 50 cal bullets under 300gr?

i think you should buy a new Stop Block if you going to shoot smokeless. i dont know if i would trust that repair with smokeless.

 

[tactical870]

I'm gonna try to find a better rolling block for the gun but the break is over 2/3 up so I really doubt there will be any pressure issues.

Its not sodered on its brass Brazed and was done along time ago has stood the test of time.
She has had hunderds of heavy loads thru her with no sign of any movement so i think your fears are unfounded.

 

[tactical870]

Didn't blow apart with heavy FFFG loads last night.

 

[tactical870]

Waiting for my .515 340 grain bullet mold (56-50 spencer bullet) and proper dies top show now. I figure it ought to be good with about 9 grains of trailboss. Should work just perfect......

 

[tactical870]

Any other recommendations for a smokeless 50-70 pistol load using a 340 grain bullet? Gonna cast some lead today as my dies and mold are here now.

Are the loads Andy posted for Rem. RB pistol or rifle?

I suspect they are for a rifle, I figure Trailboss should be a very safe powder for this gun though.
