What to do... Your opinion may mold my next project..

[Cop Bob]

Here is my dilemma..

I have had a K frame Smith and a K-22 Cylinder laying around for years.. always intending to build a PPC pistol out of them... The reamer, Barrel Blank and Rib are on the way, should arrive today or tomorrow...

In order to get the barrel I wanted, ( I only need about 7 1/2" of it ) I had to buy a 28" blank from Douglas.. It is a 1.125 OD, .305 minor land Dia. with a .312 major grove Dia..

This leaves me with 20" +- of drop... WHAT TO DO WITH IT??????:banghead:

My thoughts are... Use it for a Jack Handle, or an attitude adjustment tool...

OR, Build a single shot rifle/carbine.. in ???? .327 Maximum...? Something else that will work with that bore and bullet selection??? I dunno, maybe even wildcat it... neck something else down to that bore size..BUT WHAT???. custom dies and reamers are expensive, but what the heck, only gonna do it once... I've blown a lot more on a lot worse.. (race engines that lived 15 minutes) This will be a bit more long lived...

What type of action... where to get... a High Wall, Mini Sharps, full size Sharps.. Martini..#1 Ruger.? Not a big fan of TC or a break action like an H&R.

I have a full machine shop in my garage with Mills, lathes.. tooling of all types... access to an EDM... Maybe turn this into a year long project and grab some drawings and make the action too... Heck I dunno... I also have a full accompaniment of Routers, planes, and other implements of wood destruction.. not that I'm any good with em.. But I have learned how to pick splinters...

It would just be a ranch gun, Coyote buster, entertain the kids... mostly entertain myself...

Any Ideas... I'm open to suggestion....

A 7.62x39mm carbine on a Savage short action with a PPC bolt face swap.

I've always wondered what it would do when freed from the 45kpsi SAAMI spec, and taken up to 55-60kpsi, which would be "safe" in a Savage action. 125gr .308" bullets intended for the .30 RAR might work in that barrel... I don't know where to get those bullets though... but the .30 RAR is a 60psi cartridge

Or how about a 7.62x25mm (Tokarev) with a 16.25" barrel and blast coyotes with some 90gr XTP's or 110gr .30 Carbine bullets. And surplus ammo is CHEAP.

It's a thought... bullet selection is somewhat limited.. With a .312 minor Dia,a .308 bullet would leave a .002 gap per side, with only .0015 gripping the land per side.. that's a bit loose. I'm really one of those "One Hole" accuracy freaks... but it is a thought. Humm...55-60kpsi... that's pretty warm.. Possible...

I built a 256 Win Mag on a Winchester 37 action (410). It was a beater with a bulged barrel so I didn't feel like I was desecrating a collectors piece.I chose the 37 over an H&R simply because the trigger on the 37 was very, very nice. Added a scope and it was a great little single shot.

How about building the single shot using the old Ithica single shot lever action, the model 66?

You should probably use .310"-.311" bullets for the 7.62x39 anyway, it's just that the 125gr bullet for the .30 RAR is a "big game" bullet, and I was thinking outloud.

Sierra has a 125gr .311" ProHunter bullet, and there are a bunch of others.

Or .303 Brit/7.7 Jap bullets (.311"-.312") but most of those are too heavy. Accuracy for the 7.62x39 from a good barrel will be stellar... of course there's no need to push the pressure limit... just a thought.

How about a really accurate 32-20? A nice single shot action with that barrel would make a great modern rook rifle.

OOOOOHHHH... That would be pretty cool.... But what action... The Rolling block is pretty simple to built, drawings readily available, but the triggers generally suck and they are not that strong... Now in a High Wall.... It would work well with the 1-16 twist too... Me likey !! Brass, dies, and reamer readily available... That big old inch & an eight barrel would be fugly.. BUT, I can alway mill it into an octagon, flute it, or twist it... EDM a break into it.. old school meets.... Humm.... Got me thinking...

I will research a bit on loads and preformance... see if there is a real advantage over that case vs the .327....

That didn't take long..

Case type Rimmed, bottleneck
Bullet diameter .3125 in (7.94 mm)
Neck diameter .327 in (8.3 mm)
Shoulder diameter .342 in (8.7 mm)
Base diameter .354 in (9.0 mm)
Rim diameter .408 in (10.4 mm)
Rim thickness .065 in (1.7 mm)
Case length 1.315 in (33.4 mm)
Overall length 1.592 in (40.4 mm)
Rifling twist 20"
Primer type Small rifle
Maximum CUP 9000 CUP

With the case length and base diameter we are WAY over the case capacity of the .327 max... The original 9000 CUP limits... well, we know that with the right action and tolerances, that is out the door... (read ruger only type data)

I had not even considered looking at a case design that old.. but you may really be on to something.... Me Really Likey for it art Cool...


But I'm still OPEN to more suggestions.... PLEASE.... we definatly have a contender here but feed me more....

Gun cane! Black powder maybe. Even without a maker's mark I think a gun can is worth a couple hundred bucks. Of course you will probably go to jail for manufacturing something like that.

Single shot shotgun action with your barrel chambered for 303 British. Great medium game single shot. Light and easy to handle.

I'd love one on a BrazTech (CBC) 12 gauge action (underlever)

But hey, even a nice old JC Higgens exposed hammer top lever would be cool enough

Don't get too enthusiastic about the hot rod potential of the 32-20. The brass is really thin and won't hold up for long with hot loads.

I was thinking of low power loads, quiet, no recoil but extremely accurate and hard hitting on small varmints within 100 yards.
