Loading 150 gr Collarbutton in 45-70 with Trail Boss?

[kevinsmith5]

HAs anyone here done it?  I'm shooting for low velocity, but can't find any data.  Figure if I fill the case to 70% that's 16.5 gr and it leaves .2" under the bullet of air.  Can I go less?

I'd go less, much less as a matter of fact.

Out of a 32" barrled H&R Buffalo Classic:

16.5 gr gives a velocity of 1600 fps +/- 20.

10.1 gr gives a vleocity of 1195 fps +/- 5.

Might try lower loads some time, but the 10.1 produced a 50 yard offhand 3 shot group that was an upside down Mickey Mouse, the bottom two a little closer and it would be a cloverleaf. 1600 fps load shot more of a pattern than a group, didn't even bother trying to measure.

Not Trailboss but some low velocity loads.

I do not have a collar button mold but I do shoot a lot of .457 round ball out of my 45-70s.  They are quite accurate at up to 25 yards.  Generally I carry a few of them with me when deer and elk hunting.  I use them on small game like grouse, rabbit or squirrel that I might come across when big game hunting.  I usually carry a single shot Sharps 1875 rifle when hunting so all I have to do is drop  the breach block take out the full power load and slip in a RB load. My RB load shoots to POA at 25 yards while the full power load shoots POA at 135 yards with the same sight setting.  I have had a lot of small game dinners when no big game was around.  I generally load 8 gr of Unique and push a RB right down on top of the powder.  I coat the RB in lee liquid alox before loading.  By the way this is exactly how the army made gallery loads for practice except they used black powder.
