Has anyone ever developed a Load for a 30carbine & 150gr bullet?

I'm actually looking for a SUB-sonic load for use in a suppressed rifle.

I can deal with modifying the gas system (either enlarging the gas port for more impulse OR making a new gas piston to reduce effective stroke) IF necessary.

But I think the surest way of slowing it down is to use a heavier bullet and a smaller charge of (Slower?) propellant.

In terms of what specific bullet? I'm thinking the 150Gr Soft point that Remington makes for the 30-30 cartridge (seated below the cannelure obviously)

there is some data out there but you'll have to dig for it.
i have seen it but never paid a lot of attention to it.
i'm pretty sure they weren't using it in a carbine though.
i'd bet you could easily use some 32-20 data though and reduce regular loads down to sub-sonic rather easily.
the 125 gr bullet for the remington 30 rar would be a good candidate for this too.

Well, it's gotta be a round nose and It's gotta be a soft point

Mostly because it must feed from the magazine

Allan, I think I would look at the "lasc" website. It is a website almost totally devoted to IHMSA and cast bullet shooting, if memory serves. I suspect someone has done exactly this, but I could be wrong... And I am sorry, but the URL for the site escapes me at present.

Cast bullet sight doesn't sound promising...

I've shot cast bullets in an M1 Carbine
and though I have a gas cylinder wrench I'm not particularly excited by needing to clean lead out of the gas port again.

I will say a search for it provides nothing useful in the first several Google search pages.

I know more about the LA superior courts and the Louisiana Supreme court and the Law School Admission Council (Google Assuming I can't type)than I wanted just from the search page blurbs...

Allen,

I've been shooting cast bullets in many gas operated rifles like AR15's, AR10's, Garands, M1 Carbines, SKS's, French MAS's, etc. for many many years. I have never had lead in gas ports, AR gas tubes, or the rest of the gas systems. If you do they you don't have your cast reloading down pat. Don't believe the BS about plugging up AR gas tubes. If a gas port snags a piece of lead, it's not the bullets fault but the gas port. It may have a burr or is bad from gas erosion.

With that said I did have a load for a 150 grain cast bullet, that I sized and swaged down from a 150 grain RCBS .357 SWC bullet. I'll try to dig up the load, but I can tell you it was with the faster powders like 2400, 4227, and Unique. It wasn't a smoking hot load either and yes it did stabilize the long bullet. I'll try to research it for you.

I load my .32 H&R Mag carbine to 30 carbine levels, so, I suspect load data for the .32 H&R would be a good place to start.

I have loaded the .32 H&R with 165 gr LFN .30-30 bullets. Don't recall offhand what powder but I suspect it was H110 since I was not going for low velocity loads, I shot these at Silhouette targets at LASC matches.

I would think that Trail Boss would be ideal for subsonic loads.

I think Handloader or someone recently did an article on the .327. Data for that would be helpful.

From: Reduced Load Roundup, P.G. Wilkinson, Handloader's Digest, 9th. Ed.
"A charge of 11 grains of IMR-4227 gives the Schuetzenplinker [a 154-gr. swaged plain base bullet from now-defunct Alberts] about 1450 fps in the M1 carbine. When seated to fit into the magazine it feeds like a champ and operates the action semiautomatically. Its velocity is really too much for top accuracy, but with lighter loads this long bullet tips somewhat - it isn't stable in the carbines' 20" twist. Accuracy is "minute of beercan" at 50 yards."

From: M1 Silhouette Loads, C.R. Robertson, Handloader No. 156, Mar. - April 1992
150-gr Sierra 7350 - 14.5 - IMR4227 - LC53 case - CCI400 - 2.120" COL - 1522 fps
"Good all around big bore silhouette load."

"For medium power loads, AAC1680 or IMR-4227 coupled with Hornady 150-grain (no. 3031) Spire Point or 150-grain Sierra spitzer (No. 2130), 150-grain Nosler solid base or even Remington 150-grain softpoint have good potential. All gave excellent accuracy plus good knockdown power. For hotter loads W-296 gave best results using Hornady 130-grain (No. 3020), Sierra 135-grain (No. 7350) or the previously mentioned 150-grain bullets. All gave outstanding accuracy plus lots of energy left for rams at 200 meters."

There's data for 130- and 135-grain bullets, but I listed only the data for the 150-grain bullet, which was the heaviest one tested.

From: CB's in .30 Caliber Pistols, TFS 87-11, Sept. - Oct. 1990
RCBS 309-165 SIL (174-gr) - 16.5 - Reloder 7 - 1497 fps - "seated with the lube groove just outside the case" - heat-treated wheelweight bullet with 2% tin added.

From: Silhouette Load Development Parameters, TFS 96-17, March - April 1992
"I used ammo loaded in this way to fire a 100 yd., four group average of 1.679", with a best group of 1.104" in a CBA Regional Match. Not bad for a cartridge that ain't supposed to shoot! The load was the SAECO #301, cast of heat treated WW + 10% mono @ 200 gr. with 13.4 gr. of H4198, F205M primer and R-P case. The gun was a 10" T/C Contender with a Burris 10x IER scope."

From: Reader Bylines, Handloader #196, Dec. 1998
"The first load was 7.0 grains of 2400 with the 170-grain [Lee] bullet. It would not work the action, and the bullet keyholed on the target. Increasing the powder charge to 7.5 and then 8.0 grains did not improve anything. I then tried the 150-grain [Lee .30-30 flat point] bullet with 8.5 grains of 2400. It was very accurate, worked the action most of the time and did not keyhole on the target. I increased the powder charge to 9.0 grains of 2400. It was still very accurate, worked the action and did not keyhole. [COL 1.657", Win. or CCI SR primer, .309" dia.]"

"I have been shooting this load for about six months. It gives me about 3- to 4-inch, five-shot groups at 100 yards, which is about what factory 110-grain FMJ loads shoot."

From the comments of the various authors, the 20" twist in the Carbine and in early Contender barrels did not work well with heavy (long) bullets while the later 10" twist (as in the .30-'06) does.


This is from another forum it's not my post. Notice that some if not all of these were shot from a TC with a 10 inch twist. Like noted they tip some from a Carbine's 20 inch twist. You just may be better off with a cast bullet as they do tend to be a little shorter then their jacketed brothers.

If you are going to use a suppressor, you must be very concerned about bullet instability causing a baffle strike.

A 150gr bullet designed for the 30/30 might work, or maybe the Speer 130gr bullets, if they still make them...
