1A1 Ammunition Problem

Thanks. I knew 5.56 NATO was higher than .223 but just assumed 7.62 NATO would have higher pressure than .308, I stand corrected.

I stood corrected before in an earlier post.

That is true for .223 vs 5.56 NATO. 5.56 NATO is higher pressure than .223, whereas .308 is higher pressure than 7.62 NATO.

Was presented a Springfield M1A1 in 2012 but never fired it until 2018. I was using 7.62 mm ammo and when I fired it
the bottom of the bottom of the magazines blew out. Unfortunately I felt it was a magazine problem so I fires a few more round. Again the bottom of the magazines blew our and the stock cracked. I sent it off to Springfield and they replaced the stock and said it was the ammo I was firing. Fast for to 3 weeks ago and I fired in again and the bottom of the magazines blew out. I quit firing the first time it happened. I took took in to a gunsmith who said it was the ammo. He told me to check the rifle and it should have the ammo type on the receiver. When I field stripped the rile I found "308" stamped on it. I have purchased 308 ammo and hope this will fire w/o a problem. I will update after my test fire.

Some people never learn.

I was not clear in my original post. After the 1st incident, when I got it back from SF, I changed the ammo to American surplus 7.62 MM. when I shot with this ammo the blow out happened again. I will be shooting 306 ammo this weekend and I will post and update after that.

I’d stick with what is working with the M1. Personally I know trying new stuff or trying to make it work is fun. But at what cost? Just remember it’s already shown that the ammo you been getting is something else.

I purchased a box of 308 and fired all 20 rds, using the original magazines, without any problems.
