Anyone try an Auto Ordance recoil spring in GI?

Forgive me if this topic has come up before, shot an IBM carbine today that seems like could use a new recoil spring. Checked Midway and they had an AO recoil spring with no reviews, small print said made for AO carbine only but thought about trying it a GI model,was curious if anyone already had?

Good point floyd! Made up some new reloads using the Rocky Mountain 110gr fmj, while shooting twice only got a click instead of a bang. Turned out those 2 needed a little more push on the charging handle to get fully chambered. That's why I thought a new recoil spring may help

A stronger spring might very well solve the problem, but run some commercial loads and see if the problem persist. Like mentioned, a out-of-spec reload will cause the same problem. A carbon or unfired powder fouled chamber might be enough to cause issues, especially on a tight chamber. I will occasionally have the issue with reloads. “Plunk test” your reloads to see if they chamber and extract by hand. A fresh spring might very well correct it, but won’t hurt to check the ammo and scrub the chamber. Dies do vary and wear out. Long brass can sneak in as well. Accurately measuring head space never hurts either. A tight action is more prone to chambering issues. Those commercial springs will usually work, if the carbine is in good working order.

All good suggestions! I had just trimmed these so shouldn't be an issue with case length, I don't clean the chamber too often so that could be an issue. Yes use Lee carbide dies, wouldn't hurt to tumble the cases a little longer than I usually do.
