.45ACP barrel length?

[Greywuuf]

I finally found this message thread and thought I would add what little I can.
First off the making 45 acp brass from 308 is NOT easy well ok it isn't hard but it sure sucks, a considerable amount of case wall must be removed either by inside reaming or outside turning. secondly, I see it sorta mentioned, but lets not forget that there are at least two standard 45's out there, the pistol with bullets in the .451-.452 range ( some older guns were actually .454) and the rifle which is normally .457-.458.

and last I have a 21" winchester '94 in .45 Colt ( long colt if you prefer) and I regularly shoot my heavy revolver loads in it and I would not consider it even remotely quiet. granted I am pushing 300 grain cast slugs over a pretty healthy dose of H110, and it chrono's substancially faster out of the long tube ( several hundred feet faster... in the 15-1600 fps range) as compared to 1100 in a revolver (from memory and generalized I didn't dig out my chrono log and look)

interesting concept though... I might have to dig up some unique loads and see how it sounds about seven grains is a decent compromise in the LC case with 230 grain ball bullets (cheap too as it works out as an even 1000 rounds per pound of powder) if memory serves thats about a 900 fps load in the revolver.

gotta go get ready for winter

JUST when I forget this project,,,someone posts again and brings it BACK up!
Glad you did, this just sounds like TOO much fun.
Remember, the 45 ACP round would be fun BECAUSE of so much factory ammo of so many variations [loads] out there. Probably still some old military surplus ammo out there???
My only balking point is the price of a good .451" barrel blank. Fitting will be in house as many of my buddies own lathes and such [me included] Wish I could find a factory take off to fit to my Ruger 77 Mark II switch barrel 'fun' gun.
I want to try some "45 CB Caps" for plinking.
I actually DO need something for close range coyote culling,,could this be it?
I have to be able to control ricochete, tho. Don't want a roundish 45 ball bouncing thru a subdivision after I shoot a coyote in a nearby pasture or farm wood plot.

You are an evil man Alan, I have got a whole new direction to go experiment with on my lever gun now... and dang if a switch barrel short action don't sound like a good idea too. I have often thought of building a Delisle type carbine out of an old mauser action I have lying around....

hmmm, now for a really interesting question... is anyone familiar with how a 1911 extractor will sometimes hold a to short cartridge tight enough to make it work ? Do you supose a mauser claw would do the same ?


So I could in essence chamber my mauser mini plinker for oh like for instance a 45-308x1.5 and then shoot 45 win mag and 45 acp in it as well ?

One of these days I am going to either blow up or least be really fun to watch !

Quote from above link...
"Our insert barrels have a standard length of 10 inches and are $65.00 each. This is an excellent length for many calibers, particularly the 22LR, 22 Mag, 32ACP, 38 Special, 45 ACP and 45 Long Colt. Pistol barrel lengths in these calibers are often less than 10", yet they still achieve excellent results and great hitting power. Six inch shotgun inserts shoot better than pistols of the same length.

Longer insert barrels are available in all calibers. While more costly, they have several advantages. The longer barrels develop more velocity and hit harder, while reducing the noise of the shot. The 32ACP, 38 Special, 45 ACP and 45 Long Colt are surprisingly quiet in the longer barrels. The extra length is particularly useful in calibers such as the 45-70. The use of the 45-70 inserts makes an effective double rifle or combination gun at a very reasonable price."


This is an interesting idea for quiet loads without a suppressor. It would make sense that using a 10" pistol caliber insert in a 26" 12 gauge barrel would allow the area forward of the insert to act as an expansion cahmber and cool some of the gases which would ordinarily be heard as muzzle blast from the pistol round. Sort of like a 6"x.72" suppressor with out baffles or an endcap.

Hmmm... Yes it is. Going this route I'm thinking the smaller case and bullet diameter the quieter it would be. I see that the 357 mag isnt offered, I was thinking with heavy bullets, but the 38 sp shooting 148 gr would be almost as effective.

I notice that they say the longer inserts are quieter. In a standard barrel yes but with the long 12 ga barrel I'd guess that maximizing the expansion chamber by using the 10" insert would be quieter. So which is best, the most effecient powder burn in the insert or the largest expansion chamber?

In a TC shotgun barrel I suppose the fastest way to reload it would be to open it and poke the empty case out of the insert with a cleaning rod. Unless...the back of the insert can be cut like a chamber allowing a handgun extractor to work.
EDIT: Oops, the TC guns extractor functions like a break open shotgun does, duh.

Regarding an endcap. I've never heard that taping off the muzzle to keep rain out of a barrel was illegal. So what if the tape happens to have an X cut in it?
