What Caliber? If you are talking 45/70 I would be interested also to see about 2400 as I use that in my milsurp and 308 cast loads. Jim

TCLouisRCBS 300 gr. GC
This is for practice loads for my TC/Remington Rolling Block.
Ok, who has a load for the RCBS 300 grain GC using either Unique, Herco, or Blue Dot?
How about 2400?

<Guest>I have been using 21 grains of 2400 in the 45-70, under the Ideal 457124 and 457483. The former is a plain base bullet that casts about 400 grains in my alloy; the latter is a 385 grain gas check design. I stuff two sheets of TP over the powder, which completely fills the case under the bullet. This has been my old standby load in Trapdoors for 40 years, and in the Rugers for about 20 years. Very reliable, excellent grouping. I have never tried a lighter bullet, but would be interested in your results.
Resp'y,

z1rMy silhouette load is 14.6 grains Unique with an LBT 405 GC. You can start there but I suspect 15-16 grains would make a nice load.

DE HillyerHi TC- This is a little off topic- forgive me! One friend shoots Lee tumble lube 45ACP pistol bullets for practice in his 45/70. Yes, the Lee bullets are .451 and the 45/70 bore is .458. He wraps teflon tape around the unlubed bullets and shoots them with a few grains of a fast powder. Accuracy is respectable and they have more power than you would think. ( He uses this bullet as it is a 6 cavity mold.) We have a "redneck" cowboy range set up that is 1/2 size silhouettes (chicken &pig (50 M),turkey(75M),ram (100M)). That load does just fine offhand on those targets. But the teflon looks like confetti (sp?) at each shot. Dale

RicochetFor 300 grain jacketed bullets in .45-70 I've shot lots with 33 grains of 2400. A Lyman manual load. Velocity's somewhere in the 1700s with the 300 grain Hornady JHP from my 22" Marlin. Makes a big, bright flash. Ought to work with a gaschecked cast boolit OK.

Paul BraskyThe Cast Bullet Assoc.'s journal, "The Fouling Shot," has this recommendation from Frank Marshall, Jr.: "...13grains of
Unique seems to propel almost any reasonably soft lead bullet from 250 through 400 grains in any model .45-70 with a high degree of accuracy." (p.167-23)

DE HillyerHi TCLouis! I am thinking it is 3 wraps but the wraps are not as important as the size after wrapping ( I think). He uses the TL452-200 swc (tumble lube) slug because we robbed the pins out of the 230 tumble lube.
I really don't know the powder or load. But I will try to find out. I know it is 5 or 10 grains of something- so it is not a slow powder. He raises the muzzle before each load to postion the powder back to the primer.
The barrel is squeeky clean after a day at the range. We have thought about "lapping" this mold out to .458 and tumble lubing the bullets for use in the 45/70. (you know- plinkers). But I think this load has as much power as a 45acp round. So it is not a plaything. But we make the bullets by the billions! Dale

ClarkI like a .457" soft lead ball over two layers of poly porpalene wad over 1/2 gr Bullseye, seated deep into the case to compress the powder. This gives pellet gun noise for 1" of wood penetration.

So how many wraps of eflon tape and how much of what powder does your "friend" use to load and shoot the plink and play loads?
Sounds like the perfect thing for here at the house (neighbors moving closer and closer) when I am too lazy to drive to the range (6 miles).
I already have the 45 ACP mold and I sure do like cranking out six at a time . . . like the recent 30 cal soup can mold!
