This was not a test ,But a reloading accident.I had a Savage 110 in .270 win.Somehow

I let go of a round that blew out the ejector and some other assorted parts from the bolt. Like vapodog said I had to beat the bolt open with a nylon hammer Then use a rod and the same hammer to get the brass out .It glued the primer to the bolt face.( I guess I am still lucky to have all MY parts.)After a package from Savage customer service the 110 was back in shooting order .It did not cycle reloads anymore but the factory stuff did just fine.
BTW ............Vapodog ,You have gotten me scared about my C.R.F. winchester now.I am getting 3350 F.P.S. with a 140 gr. nosler ballistic tip , 26" bbl. in 7 MM Rem. Mag.I have yet to see any pressure signs.If anything happened to it like happened to the savage it sounds like I ain't going to like it ....LOL
