Thanks, good data. Did the 30gr pyro P shoot the best ? Is that why you have some inch figures below the data?

I got caps!
can I push this to 37 or 40 gr, what is the ceiling?
The ceiling is way more than you can pack in that cylinder!! You can't overload a cap gun with bp.I got caps!

I actually started to do that just recently, but some fellas saw me shooting and started talking, and that was the end of that. Not that I minded, I enjoy talking about old guns. Here is a partial list, I still got a couple of powders to try, and some conical bullets also. 27 grains with a rb is barely loadable in my gun, my standard charge is the 23 gr. When I complete my results, I will start a dedicated thread.Great data.
Could you do the same with .36?
Preferably with a 1851 colt navy.
You're getting pretty close to 30gr with some of those loads. Is that close to the max chamber capacity?I actually started to do that just recently, but some fellas saw me shooting and started talking, and that was the end of that.

27 grains is absolutely the max in MY gun. The ball will only seat below the cylinder face with way more effort than I like. I don't shoot max loads, I just did it experimentally. 23 grains does what a .36 navy was designed to do. Notice there is very little velocity gain with 27 vs. 23 grains, but the battering of the wedge and blown off caps, dropping into the action are very real negatives in using max loads. For conical shooting, I will drop down to 18 grains.You're getting pretty close to 30gr with some of those loads. Is that close to the max chamber capacity?
I just spent the day with my Colt 1851 .36 and tried different loadings. All shots were with a ball and felt wad. 30grs absolutely fills the chamber to the top, so that's that. I normally shoot 20grs and I get plenty of velocity. In addition it is more economical with 20grs and it won't stress my expensive Uberti. You definatly get a bigger bang with 25, but why do it? If I want/need a more powerful load, I take my Remington 1858 .44 along with a load of 35grs and wad/rb. I usually carry it cross draw in my sxs.27 grains is absolutely the max in MY gun.

That triple 7 load is as fast or faster than a traditional full power Walker punch, isn't it ?1858 rem. 8" chrono if anyone cares.

Zero malfunctions or cap jams. accuracy about the same for all loads, 3" groups at 25 yards. All rb groups low (3-5", lower the higher the fps) and 2" right. Conical load zero elev. 2" right.

And soft ones !Only loose wedges get battered.
The pressures for loose powder and ball are around 11K psi - 13K psi and yes, wedges can get bent with those pressures.

This '60 Army wedge has perfect edges and has seen right at 400 rounds of 21K - 23K psi ammo pushing 220gr. and 230gr. jacketed conicals.
