    3x fired brass not chambering - 300PRC

    I agree 100% that I have not solved the issue. I'm @ a loss of what to do to correct the issue . I have never used a body die before, but from my reading, it sounds like it will push the shoulder back as well. Is this thinking incorrect? I'm using a Hornady comparator (0.420, D) and calipers...

    3x fired brass not chambering - 300PRC

    Thank you for the drawings and info. Interesting observation - after resizing (bumping shoulder) back on all ADG brass to .008" all rounds were able to chamber with the Redding die. However - there is a very distinct line on the case, where the lube has stopped, showing how far down the brass...

    3x fired brass not chambering - 300PRC

    I tried my buddies Redding s-type die and that got them down enough to chamber. Will be picking up one of them in the short term

    3x fired brass not chambering - 300PRC

    Holy smokes, that video was awesome! I know what I'm doing next week - sending fired brass to whidden for a new die ? I've used them before with a ton of success

    3x fired brass not chambering - 300PRC

    To be clear - ADG brass is top notch, it's all I shoot in 5 other rifles. I only mentioned the name above in hopes that I'm doing something silly/stupid and there is an easy fix. Not to nock the brass / manufacturer.

    3x fired brass not chambering - 300PRC

    i placed the round behind the extractor before pushing the bolt in - would not chamber. Also placed round in magazine, pushed bolt forward until it was tight, reversed bolt slightly and then pushed back in - would not chamber. Did the same thing with the hornady brass and loaded factory rounds...

    3x fired brass not chambering - 300PRC

    Attached is a picture of measurements for hornady 300PRC brass (6x) compared to ADG (3x). The hornady brass chambers perfectly. Measurements are taken from the base of the case using a tool scope. I took measurements from 7 different locations. Hornady brass on left, ADG brass on right

    3x fired brass not chambering - 300PRC

    What measurements in particular? Where on the case? I've got Hornady brass that I have at 6 loadings in same rifle and have not seen this issue if that helps. Also m using a Forster coax press

    3x fired brass not chambering - 300PRC

    I'm having a problem with my 300PRC, in that 3x brass will no longer chamber. Brass was resized and the shoulder was bumped back 0.002", just like the first two times I reloaded it. This time however the bolt is hanging up at the downstroke. Checked headspace and it is correct, same as the 2x...

    Dent below case shoulder

    Mystery solved...My depriming die had a piece of media in it. I used it on Hornady brass but not the ADG. Thanks guys!

    Dent below case shoulder

    Measuring headspace using a Hornady comparator (0.420), both are giving the same measurements. The Hornady brass is 0.005" longer overall length, only difference.

    Dent below case shoulder

    Thanks for all the replies. It's been fired 1x. I do not see it on ADG 1x fired brass, which is why I'm thinking it is not due to the chamber. I fired 10 adg and 10 Hornady (verified no divot before firing) this morning and none showed divots post firing either. Will clean then and then size...

    Dent below case shoulder

    I just finished full length sizing a hundred 300 PRC Brass (Hornady) and noticed a "dent/divot" on one side just below the shoulder. It is in the same spot on about 70 of the 100 brass. Any ideas what could be causing this? I cut one open and there is no discernible marks on the ID of the case...

    Had an opportunity to take before and after pictures using Wipe-Out for a 4 hour soak. Focus was on the "cracking/scaling" in the throat and stubborn copper in the lands. I tried 2 common copper and carbon solvents previously as described in the previous threads. In my opinion, wipeout...
