I am new to rifle shooting. I saved up and just purchased a brand new Savage Model 12 BTCSS. I took it to the indoor range just to fire it a few times before I use it at long yardage.

When I pull the bolt back, the brass ejects just fine, but does not pick up the new one to load in the chamber. I can see it there in the Detachable Box Magazine, but the bolt just slides back and forth.

I have tried Remington UMC and Hornady Vmax. It does not appear to do it on the first round, but usually the second round.

I measured the brass length and OD and are as follows...

Remington UMC 45gr = length is 2.315" and OD's are .467:
Hornady Vmax 55gr = length is 2.347" and OD's are .467:

I took out the bolt, wiped it down, lubed it again and ran the action back and forth about 200 times.

What else should I try? ???
