Clean it. Think carbon ring.Hello everyone, long time reader first time poster. Have a 300 win mag purchased off here that I personally have shot probably 200+ rounds out of and no issues. Went to shoot today with the same federal hybrid hunter factory ammo I have always shot and I am unable to chamber a round. The round will not go past the neck, tried 3 boxes of ammo including one I had partially shot previously. Also tried to chamber a piece of brass I had previously shot and same thing. Forced it a little on the empty case and it left some pretty bad marks. I can upload a picture of that later. Any ideas? Thanks!!
Rifle is a Stiller action with a shilen barrel. Unsure who did the smithing
Yes for the Teslong Borescope. My $78 one, with wifi to iPhone or Android, works great.First thing, get on Amazon and order a Teslong bore scope . Hopefully you already figured and fixed the problem, but the scope runs $50.00 to $75.00 depending on model......cheaper than 2 boxes of good ammo, and will answer many questions.... Hope you have it figured out....rsbhunter
Seems like it would be the end of a protruding rail screw. Once when remounting my 20 MOA pic rail, on a Remington 700 action, I accidentally reversed the front and rear screws, and couldn't close the bolt until I reversed the screws. (I see that the OP has a pic rail under his NF scope.) Mine is a 300 WM by Christensen.Can't wait to see what is causing a dent that big in the brass. Especially since nothing has been changed on rifle since last firing.
