Been looking for a project to start learning machine skills on.
would stubbing a handi to build a .45acp rifle be a project to learn on if I have a compitent teacher?

if you have a compitent teacher any project will work its how much time and work you are willing to put into something iver personally learned the harder your first few are the easier things become after that

Go for it you ain't gonna learn any younger .A 45ACp should be a fun plinker

Mr BadWrench · « **Reply #3 on:** October 28, 2012, 04:06:22 PM »

is it possible to use a muzzle loader barrel? I have a .45 cal muzzle loader that has no value to me.

Same blank my 45ACP Handi was made with, but mine is a liner barrel not a stub.

So you just turned it down till it fit in a shotgun barrel and glued it in?

How much does it weigh and was it possible to put iron sights on it?

Does it have an extractor/ejector?

Mr BW

A friend built it for me so no credit do on my part.

Mine has a scope rail but you could put iron sights on one. Depending on your shotgun barrel profile and wall thickness you might drill through the shotgun barrel into the liner barrel so some thought about that would be prudent.

Yes, liner turned down to fit inside a shotgun barrel. Note, the bigger the gauge shotgun barrel the more "meat" will be left on your liner barrel and less time spent turning it down to fit. Also, you can bore out the chamber swell on the shotgun barrel if you want to keep the chamber of your liner a tad thicker.

It has a milled ejector notch and a modified 30-30 ejector was used. THe rest of the ejector system is from the pardner shotgun barrel.

At 18.5" the barrel is fairly heavy, but I have never weighed it. A stud barrel could be a lot lighter than a liner barrel.

Liner is epoxied in place and has a rim turned on the liner to match the rim cut on the shotgun barrel so it isn't going to move.

Gun works well, it is my backyard, subsonic ground hog eliminator. THe builder of the gun harvested an antelope with it, using 45 super ammo.

What specialized tools will I need to buy?

I assume I will need a .45acp chamber reamer

is there anything else?
Im hitting a really good show saturday looking for a used 20gauge or 20gauge barrel. this show usually has tools but id be surprised to find a .45 chamber reamer.

Mr. BW,

This site has a 45ACP chamber reamer that you can rent, there is sticky thread at the begging of this forum that tells you how to reserve the reamer. You need a metal lathe and a mill if you want to do this right. Go to the "FAQs" sticky thread at the top of this forum and there is information on liner and stub projects. I would spend a lot of time going over that information and studying the pictures before I set out to build a liner or stub barrel. FWIW, it is possible to do a liner barrel or stub barrel with hand tools but it is a lot of work and the quality of the work is likely to suffer; I know this as I built one without a lathe or mill and though functional it ain't no beauty queen.

Well I did it.... there were several Handi Rifles at the recent gun show, a couple older ones with beautiful wood and a couple newer ones. I ended up purchasing an SB2 20 gauge, then ordering a barrel, reamer and extractor online.

I considered renting but $57 and its mine to keep, besides 2 or 3 of my friends all seem interested and for sure the guy doing my machine work and helping me learn a little will want one.

so far I have $238 total including all taxes and shipping for parts and base gun.

is the receiver an SB2? or is the barrel marked SB2?

Barrels marked SB2 mean nothing as to the frame it's on, see the FAQs of the H&R website pics to determine what the frame is, or call H&R and ask them what barrels can be fitted, they'll need the frame serial number.

got my barrel from Greenmountain today, its REALLY have and short too.... I cannot hardly wait.

jkpq45 · « **Reply #15 on:** November 09, 2012, 09:05:04 AM »

Regardless of SB1 or SB2 frame, your .45ACP project will be safe to shoot, no worries!

And also, good luck!

Mr BadWrench · « **Reply #16 on:** November 09, 2012, 03:15:12 PM »

Got my extractor and my reamer today...... now I just need access to the lathe.

looks like you're making some serious progress! the potential of the handi platform is quite a lot once you have access to the proper tools don't you agree?

Mr BadWrench · « **Reply #19 on:** January 05, 2013, 05:31:48 PM »

The funny part is, the guy who owns the lathe wants one and another friend wants one too... The two of them figured out a much simpler way to do the stub that what I had planned.

Dinny · « **Reply #20 on:** January 05, 2013, 05:43:54 PM »

Isn't the case head the same size for both the 30-06 and the 45 ACP? If so, would it be easier to use a 30-06 extractor?

Thanks, Dinny

Mr BadWrench · « **Reply #21 on:** January 05, 2013, 11:39:14 PM »

my research lead me to a .308 extractor because back in the day I read you could make .45 super brass by cutting down .308 brass.

Good point, we talking about all the same case head size.

Thanks, Dinny

Mr. BW
My liner barrel 45ACP Handi (GM barrel blank) is an ejector type. We had a spare 30-30 ejector so we modified it.
FWIW, I have shot Texas Ammo Co. 45 Super in my 45 ACP handi on an SB1 frame without issue. THe 45 Super works well enough that my friend harvested an Antelope with this rifle. My preferred load is a 200 g LSWC over 3.5 grains of Red Dot at about 820 FPS. Great for ground hogs out to almost hundred yards.
Keep us posted on your progress and looking forward to seeing target pics shortly.
