New to the forums, with about a year of reloading experience. Shooting a savage 110ba .338 Lm. Reloading a 250gr sierra hpbt with 82 grains of imr4350. The gun is 3 months old and the dealer threw in a box of hornady bullets, and a friend turned me on to 100 rounds of Lapua brass. My problem is with the reloaded Hornady brass, (they chamber fine) but I have to "slam" the bolt open with my palm to eject it, where as with the Lapua reloads its a very smooth close and open. Is the hornady brass that thin where its expanding way out or am i doing something wrong ??? Thanks for any help
