.45 ACP sabot .224 projectile

[Sylvan-Forge]

I want to try some .224 rifle bullets from a .45 ACP barrel, any suggestions on where to get sabots?

 

[Walkalong]

Interesting, but I don't know the answer. I'll be watching for the answer myself.

eabco sells them cheap for .224 in a .30, and .30 in a .50 (i suppose in theory you could nest them and shoot a .224 in a .50)

you might talk to them and see if you can convince them to make a 224 in a .45

Check out the .224 Boz. It's a round that was actually designed to be a .45 necked down to .224. They're next to impossible to find but I bet you could have a barrel custom chambered for you.

I might be wrong, perhaps it was a 10mm necked down. I can't really remember now.

Chamber pressure is standard 10MM. If you have a 10/40 about all you need is a barrel swap. I will drag up the info. I saved every article and writeup about over the years. Basically it's a 10mm case necked down to 224. Like the 5.7 it is more of a blow back type of round. It hits max pressure and then drops off so fast that it peens the breach face but does not have enough residual energy to cycle the slide. Most 1911's that were converted had their slide cut and lighted to the point that the 1911 style slide look like 92/96 slides

Think of it like a FN 5.7x28 round only it uses the heaver 224 bullets and drive them about 30% faster then the 5.7x28mm.
We would also be offering barrels and lightened slides. All you would have to do is remove your Delta top end and put ours on.

I can't see how you'd ever get enough pressure in a .45 acp case with a 55 grain bullet to do any good, let alone work a slide. It seems way too light for the caliber, even with a sabot that would only weigh a few grains.

I've experimented with the .223" bullet in the .30 sabot, but didn't have very good luck with them. They would shoot about minute of barn door, but really fast.

Hope this helps.

Sabotted ammo, in any configuration, rarely shoots well enough to bother with. A sabotted .224" bullet, even if sabots exist and I doubt it, won't cycle the action.

Thank you all ..

taliv, I'll see about contacting them if no one else is making 'em.

MASTEROFMALICE, aye, that's a neat round .. as Walkalong's post shows, the boz is a necked 10mm.

ReloaderFred and Sunray, not even if they are driven pretty darn fast out of a 4.5 to 5" barrel with a light weight recoil spring (wolff goes down to like 7 pounds) ?


I'm not looking for gilt-edge accuracy, just max velocity out of a 45-50 grainer+sabot weight .. say, minute of badguy at 25 yards ..

Not sure on the barrel lengths but RBCD is advertising a 90gr bullet at 2036 f/s ... and an 80gr at 2375 ...

maybe .. just maybe with the right powder?

 

[Sylvan-Forge]

Well, I've been looking and not finding anything ..

Hey, Hornady has some .45/.40 sabots .. maybe I'll play with those first ..

For .22, maybe a slightly heavier sabot could be cast with a little weight to it for helping to develope pressure ..

With a .45ACP's rifling twist rate of 1 in 16", stabilization will likely be an issue.

Hornady also has some 357 sabots for 45. These are in their muzzleloader series and the package says 44 instead of 45. Muzzleloaders are so confusing because a 44 muzzleloader can be on of 4 different actual bore diameters, most of which are near .451.

In 357, you have a lot of choices in weight (little 380 bullets in the 80gr range to heavy 357's in the 180 and 200gr range). As someone else said, you can't go to a very long for caliber bullet because of the slow twist of the 45. You could probably get an 85 to 100gr bullet going fast (at least 1300 ft/sec). You're on your own as far as load data for these, so be careful and at least try a ballistic computer to see what is achievable.

Thanks guys ..

For the .22 I'd like to use a specific 45 grainer .. hopefully it will be stable to 25 yards or so .. guess I'm goint to have to see if anyone is interested in making sabots or learn to make them myself since this is going to bug the crap out of me until I try it.

suemarkp, thanks for the heads-up on the hornady 357 sabots .. that'll be cool to try
