Load problems maybe?
I just got a new rem m700 7mm stw. I loaded a few rounds just to try it out. The first shot felt good, I went to remove the spend round and it wouldn't extract. When I got it out it wouldn't extract after firing also. My load is a mellow load
New unfired nolser brass
Fed 215 GM primer
speer 160gr #1637 loaded to 3.530" according to speer manual
fired brass very hard to chamber (it wont), new stuff and the other loaded round is like butter.
I am at a loss, I dont know what to think. Any suggestions, this is the first time I have ever had a issue with handloads. Maybe chamber proplem with the rifle?
