Heavy 9mm loads for carbine

[impactco]

I have a J&R Eng M80 carbine that I have had since the early 70's that will not cycle standard 9mm loads. The only ammo that has worked consistently is this stuff, of which I only have a few boxes remaining:

I ran some of this through a chrono. Out of the 16" barrel, I was getting about 1400 fps.

Anyone have any reference to a recipe for an equivalent load?

The only difference is that mine has been modified to meet Cali compliance (fake can, grip wrap):

Thanks.

Pull one apart, weigh the powder and check the bullet grain and go from there???

[impactco]

There would be no way to know what powder they used, but I will do that. Still need a recipe.

[bombadillo]

True true. Still a newb to reloading, but slowly learning day by day.

I have box of old (70's vintage) Israeli Military Industries 158 grn 'blue tip' 9mm that was made for the Uzi. Supposedly it needed the extra weight to function reliably. Have you tried 147 grain stuff yet?

a buddy of mine, back in the day, made a gun for the police. it was called the M68. it was a carbine and they were doing testing with it to see how fast they could get the projectile. they got to the point (at the range reloading) that they filled the case with Bullseye and got around 1700 fps! now i havent checked it thats a ok load, but i do know they used fiocchi subgun ammo and it worked to.....

you could try a heavier bullet at the same velocity, like 1050-1100 fps. (if thats a recomended load).
i take no responsiblity for this btw ;)

The M80 is the off-list successor to the on-list M68. It's basically identical except for a rail and charging handle on the left side instead of the top.

Here are the variants:

Wilkinson Arms

When Penney moved National Ordnance into their facility at 235 S. Irwindale Ave. in Azusa, next door at 231 S. Irwindale was a Go Cart parts manufacturing business run by Ray Wilkinson. Penney and Wilkinson became acquainted with one another and the friendship continued after Penney moved to a different facility in Azusa, where he manufactured the Alpine M1 carbines. Wilkinson's business eventually closed, and Penney sold Alpine. In 1968 Penney funded Wilkinson and they developed a 9mm carbine known as the M68, and later, the M80. The difference between the two was the location of the bolt handle. It was moved off the top of the receiver and onto the right side. The company name they were produced under, was J&R Engineering.

Gun World April 1969

The carbine proved to be extremely accurate but suffered from a persistent extraction or ejection problem. But the thing that killed the entire project was the 1968 Gun Control Act and it's ban of mail order gun sales.

Wilkinson eventually solved the problem with extraction and/or ejection, and renamed it the "Linda 9mm Carbine", after one of his daughters. He went on to sell the carbine under the name of Wilkinson Arms of Covina, CA. Wilkinson eventually moved to Idaho and the last several thousand Linda's he made various modifications to and renamed it the "Terry 9mm Carbine" (another daughter). Wilkinson also manufactured a .22 semi-auto pistol named "The Sherry" (yep, another daughter), and a .25 auto semi-auto pistol named "The Diane" (his soon to be 2nd wife).

I'm holding on to an M68 until the owner gets his AW permit.

"Start at the max and go from there" is what my LGS owner tells me. He's a collector and has 14 of these carbines.

Milsurp Collector, thanks for that! Mine does have very inconsistent extraction. It will go 20 rounds and then one will FTE fully or just sort of roll out of the port. I thought it was perhaps the 50+ year old ammo I was using.

One minor error in your article is that the bolt handle is on the left of the M80.

Thanks. I have a scan of the original M68 manual if you need it.

Here's the M68 I have here holding. Serial number is 220X. Came with 2 mags.
