Any .30 carbine ammo made after the specification change should have been to new standards. Ordnance was reaching out to all ammo manufacturers for propellant and primer types to fine tune the .30 carbine. Fast forward to today, manufacturing has changed and are the commercial manufacturers holding tolerances or making their product "good enough?" I would default to you on what ammo is better digested than other ammo companies

That's for sure. Armscor on the right. I personally have never had issues with it and it feeds and bangs in anything I shoot, but it's obvious the profile differs. I have noticed they seem to seat the bullets a little deeper, closer to 1.65-.66 on average. Edited by floydthecat - Oct 22 2021 at 11:18am |

I hate to belabor the point, but old bored people like me have to pass the time of day doing something. I have looked again at the thread concerning the chamber/ammo revision. One thing they did was to reduce the lead in the chamber, the space between the case-mouth and the rifling. This would in effect require a different taper of the projectile in order for the bullet nose not to solidly contact the rifling. It almost seems like the Armscor was designed with the old chamber in mind?

My 2 bits, if the OP can find any of the Korean surplus in stock try that. 2nd choice would be trying S&B, I've never had any trouble with that any carbine I've run it on. I've even been saving a case of 500 of that to use to break in a new Fulton Armory carbine I have on order due soon

Don, the OP has Korean surplus ammo which he has stated works fine, he is only having his issues with the Armscor.

Opps, missed that. Strange then, I've run 1000's of rounds of Armscor the past couple years (I found a deal on it before the current panic) and the only carbine it gave me issues with was my Plainfield before I swapped springs in the bolt

Thanks everyone. I think I got it remedied (just by feeding it mil-surp). Have only had a chance to dry cycle the ammo, haven’t been able to send any turtles to their meet their maker yet but will one day this week

Matt, where do you find snap caps/ dummies for the carbine? Locally, or is there a dealer on line? BTW, this was a great thread. It is amazing how much I have learned since I first posted this. Never thought I would know as much (but not even close to knowing half as much as most folks on this forum) as I do now though. Thanks Everyone!

Hey Rebel 92: Have you put the calipers to live rounds measuring 1) at the very base of the cartridge, 2) at mid body of the cartridge then 3) at the mouth of the brass comparing your a) Evansville 1944, b) Korean 1972 (and any other MILSURP stuff) and c) the AMSCOR loads? Further, have you looked to see if any of the rounds show rifling marks on the bullets after the plunk test? I understand that may be a tedious time-consuming project but right now it's Miller Time and is an excellent excuse to pop-a-top on a few brewskies.

The vender I bought from on ebay is no longer listed. I think probably a guy just making them on his own. If you're hand loading I think the only trick is to find a suitable material for the primers. Maybe go through McMaster-Carr looking at 1/4 inch? sheets of rubber as well if there is rubber extruded in the right diameter. Might be easier to slice a dowel than punch the sheets. Cyano-acrylate (sp?) best known as Krazyglue ought to be a good adhesive for rubber to metal. Doing a little googling there is a business in Ariz making .30 carbine dummy rounds with a rubber primer.

Ethan, I have no experience with them, I just saw that you and Matt were discussing them and remembered seeing them on ebay. Hopefully they don't pull apart.

Home made snap cap: Using a sized case: Mix a small amount of epoxy glue or maybe some J-B Weld, then, using a cotton swab smear some inside the mouth of the brass, seat the bullet in the usual fashion. Fill the primer pocket w/ silicone sealant; smooth flush w/ tip of finger. Let the above 'set' or 'cure' and ya have a really inexpensive snap cap. Works for me!

For what it's worth, the A zoom brand can't pull apart because it's made out of one piece hard anodized aluminum and even though I haven't measured one, it's supposed to be exact dimensions. I have used them in other calibers hundreds and hundreds of times with no problems.hth
