Don't run steel case thru a carbine....
Running steel case in firearms not designed for it is a good way to break extractors, wear feed ramps, and generally isn't good for something that is getting to be collectible.
Anyone try this brand, caliber, or company? This is a great price, half of Sportman Guide, but if it sounds too good to be true . . .
Planning on testing an M1 Carbine. Opinions on that ammo in that rifle?
If the gun will run it, then run it. There's no reason not to unless you are looking for accuracy. Buy a box at walmart for $5 to test out if your firearm functions with it, if it does, then move on to buy it in bulk.
This isn't a modern gun we are talking about.
The cartridge is on the small side for gas operation in the first place anyway. Add dirty steel ammo.
Some carbines have enough trouble with the dirty brass Aguila ammo.
