1851 navy cartridge conversion???

BTW, contrary to popular belief, a 'Cowboy load' is one that has a lead bullet and does not exceed 1000 fps out of a single action revolver. It is not a mouse phart or pfffttt load.

Just an observation, I have loaded .45 Colts with full load equivalant with pyrodex and shot them out of both revolver and '73 copy and have watched cowboy competitions on youtube. It appears the cowpokes need a decent power factor to meet rather than one not to exceed.
 
They do have a power factor to meet, it's just not very good. Some shooters can fire five rounds before the first one hits the target. At least it seems that way.
 
yeah, I've also been looking for something a little more stout to work up some hot .45 Colt loads. I've heard they are supposed to be a real handful if you load them to max pressures (still less than a .44 mag, but will definitely let you know you've shot something). The cowboy loads I've experienced seem to not have much more pronounced recoil than a single six in .22 mag, just louder.

.45 Colt can be loaded beyond .44 mag pressures. 44-40 can be loaded to 44 mag pressures but the thin cases wont last long. A case full of bp will let you know fired something.
 
Does anyone make a cartridge conversion of the 58 Remington. I understand that's basically all the 75 new army is, but I've also never heard much good about the current production '75's so I wondered if a converted '58 might be better. Would this frame hold up to any hot ammo, or would this still be a cowboy only gun?

Yes but it's still a cowboy gun.
 
yeah, figured I'd still be stuck with the normal load restrictions for a blackpowder frame, but worth asking. Guess it's time for another blackhawk.

Uberti makes '58 conversions in 38 Spcl, 44-40, and 45 Colts that will handle any standard velocity smokeless factory round. They will not handle "High Velocity" or +P rounds - but then again a new Colt SAA won't either. BUffalo Arms carries the Cimarron line:

I don't know what cowboy loads you'rve experienced; I'm guessing someones downloaded .32s or .38s, or possible .45s, but 44-40 case full of T7 will rock your world out of a 5 1/2 inch barreled SAA. Per the Hodgdon site, 30 gr of FFG or FFFg T7 under a 200 gr RNFP leaves the barrel at 830 fps with 309 ft/lb of energy (if i did the math right) - not enough to make Major in IPSC; but not exactly a wimpy cowboy load either. The same 30 grain load under a 250 grain bullet in a 45 colt easily makes major.

A full case of Pyrodex in a 44-40 ain't too shabby.
 
Mine have all been factory loaded .45 colt. Honestly, I was more than a little disappointed the first couple times I fired my first .45. I was expecting something akin to the recoil of my .44 blackhawk and got something much milder than a .38 spl. Maybe the same as a 9mm, but not much more than that. My father told me about the .45 he owned just destroying an oak 2x4, but mine barely makes splinters on the back side of a similar target (difference between '70 and 2011 I guess).

I have no doubt that the .45 is capable of being quite a handful, just not in any of the loadings I've had experience with.

How does the same amount of powder push a bigger bullet faster? Don't understand that.

James.
 
Power factor in IPSC is weight times velocity. 30 grains pushes both bullets approximately the same velocity. Heavier bullet = higher factor. Heavier bullet also equals highter kinetic energy.
 
Yep, ole Newton is still alive and well.

Force = Mass X Acceleration ;)

Oh, and on the recoil side....

"Each action has an equal and opposite reaction." :D
 
Sounds like I'm back in HS Physics class again. Though this is definitely a more interesting application of the theory than what we did:cool:
