.45ACP in a remmie 1858 NMA

[azyogi]

Howell conversion to 45acp for 1858 NMA

Came across these on the Buffalo Arms site. They list them for both Pietta and Uberti. My question is this, can this handle factory ACP loads or is it like the .45lc and have to be downloaded to 'cowboy' strength? [Would post a link if I knew how]

Oooooo... I likes the notion of this !!!

Great question!

I'm waiting to hear the answer too.

The 45Colt R&D are suggested to use Black Powder or "Cowboy loads". That's 35gr BP with a 250gr L-flat nose lead boolit. So I'd think say a Walker, Dragoon, ROA, R&S, and Rems in that order could but I sure wouldn't load more than a 35gr of BP equivalent probly less for a Cowboy Load... Thse Revs in weight are heavier to lighter in that same order....jus' bp rev tivia.

But the more I think about it I'd like the 45Colt and an 45ACP cylinder. I really am likin' to want a 45ACP for a Uberti Rem...I think that it's good Rem round plus more the size of a .46 Rem rimmed cart :O)

I do not think one could get 35 Grains of BP into a .45 ACP Case, even if no Bullet..!


Lol...



Just tried one, and, full to the brim with no compression, a .45 ACP Case will hold right on to about 25.5 Grains of 3F BP.

If with a Bullet, it'll be however much less the Bullet seating depth will displace, of course.

The Howell/R&D cylinder is made of modern heat-treated steel. It will withstand "normal" .45acp or .45LC loads (which should be less than about 12,000cup). The weak link is in the gun itself. Over time the hotter factory loads will damage the frame of even a steel framed 1858. I shoot mild "cowboy" loads in my 1858's with a 200gr RNFP at 800-850fps. This is only about 7000cup. With the ACP cylinder you will be fine shooting standard "ball" ammo, but from experience I can tell you the accuracy will be awful with the copper-clad 230gr bullet.

I personally own two Pietta 1858 target models with R&D cylinders in .45LC and one in .45ACP. The only thing I have gotten to shoot well out of the .45ACP cylinder is the 185gr SWC with TrailBoss powder. 4-6" groups at 10 yards. It is pretty weak too. Only around 490fps. If it were my money I would buy the .45LC cylinder. Both of mine will do less than 4" offhand at 25 yards. (6.0gr TrailBoss MBC 200gr RNFP Win Brass CCI LPP 830fps)

You can reload for the .45LC for about what you can buy quality .22lr ammo for. I usually get 30-35 reloads out of a batch of brass, bullets are $38 per 500, primers are less than $30 per thousand, and a can of TrailBoss goes a LONG way. The above mentioned load is around 11-12 cent per round or less if I buy on sale. A box of .22lr CCI Stingers is $6.50 plus tax here, which is about 14 cent per round.

Depending on your Remington, the Barrel Bore might be too large for usual .45ACP Bullets' diameters anyway...to say nothing of avoiding 'Hardball'.

But, if one load one's own, this could be worked out alright...keep pressures low...and have fun.

Full Moon Clips, and fast change Cylinders, would be kinda fun.


Then again, just the Remington's fast change Cylinders in Cap & Ball are already fun!


So...

I stand corrected ...I am too use to thinkin' 45Colt intead of 45acp... :O)

 

[Oyeboten]

Lol...there's a lot to keep in one's Head with all this.

Some days, it just rolls out my Ears and onto the floor, and under the Loading Bench, where, in reaching for it, I bump my Head on the way up, too...even if missing the Press Mounting Bolt ends...

Having not researched your source, there is also a .45ActionCowboyPistol cartridge.Not to be confused with the one most modern 1911 semi-auto pistols are chambered in, .45acp....

Umm, are you refering to the .45LC loaded to Cowboy Action velocities? To my knowledge there is not a .45 ActionCowboyPistol chambering. If there is, it has never been mass produced and is a one off.

I believe Senor Missedshot may be referring to the "Cowboy 45 special"
http://www.cowboy45special.com/

.45 Short Colt if you will, essentially .45 Colt cut down to ~ the length of .45 ACP .

 

[tango2echo]

Probably, but it is certainly a one-off chambering without a purpose. Sounds like a good way to make CAS even more expensive.

[Oyeboten]

It is amazing how complicated the present day options are becoming, for what had been pretty straightforward Cap & Ball Pistols.

Yipes!

All seems like fun, regardless, but...jus' sayin'...

The 45 Special is not a chambering that I know of, just a shorter cartridge for use in 45 Colt or 45 Schofield revolvers. It saves powder whether smokeless or black. Light smokeless loads in 45 Colt leave a lot of air space which many shooters don't like, the 45 Special is more efficient with light loads, black or smokeless.

It would be reloadable with 45ACP or AutoRim dies.

No-one makes cylinders or revolvers specifically chambered for 45 Special.

I have one of the Kirst .45 ACP Conversions for the Pietta Remington and shoot Remington 230-gr. Golden Sabre factory JHP loads in it all the time or any standard pressure (not +P) .45 ACP hardball equivalent handloads. No drips, runs or errors.
