7PRC Partition wont chamber

[Ucsdryder]

UPDATE yesterday evening i got home, sorted through some of these comments. Judd's comments stuck out to me the most about not measuring the lands correctly. thought to myself ima show him. jammed the case into the chamber as far as it would go. pushed the bullet into the lands as hard as i could, several times. getting ogive measurments around 2.427, 2.434 etc. loaded a eldx at book length 3.320 and thought to myself ima jam this mfer in there so hard it gonna chamber. and if shit gets fkd up ima let the smith deal with it. round chambered flawlessly. smooth as butter. Didnt even fight me. Didnt use force. And immediately i thought that wasnt supposed to happen. went look back into my notes to be certain i did indeed try to chamber the eldx and ablr at book length when the projectiles came in as all of this has turned into some weird blur over a period of i dunno, 2 weeks maybe. i certainly have. right there in black and white. So then I loaded an ablr at 3.320- again chambered flawlessly. put the oal guage back in the chamber and getting 2.6 numbers now instead of 2.4 numbers. took a fired case, put loctite in the neck, chambered it. 3.342 coal 2.641 cbto said aint no way. loaded 3 bullets 3.320 put em in the mag as i havent used the mag yet to this point, cycled flawlessly. took one colored the bullet with a sharpie, put it in a fired case and left long- just marks at the ogive. i dont know where the problem was, or what the problem was. all i know is the problem seems to be gone. and i aint complaining. I ordered a borescope so that i can see if maybe theres a piece of bur or something that is no longer touching anything. maybe it broke from all the banging the buttstock on the ground to get the bullet out of the lands all these times. i dont know. i didnt put clr down the barrel yet as the smith suggested so doubt it was a carbon ring issue.

I continue to be confused by everything you’ve done. When you had factory ammo load and shoot flawlessly that should have been your sign, but wasn’t.

This is going to come across as offensive, but I’m not sure you should be reloading. Why not just buy a case of eldms or eldx and shoot that barrel out.

CLR is all I use for carbon, it works great. Don't leave it in overnight and you'll be fine.

when im confused and my comprehension skills lack i usually get aggressive also. weird.

I laughed about showing me

Back when you chambered a factory round...I was convinced then it was you and your smith chambered it with a saami reamer and it was good. I just had to let you go long enough to learn some lessons on your own. Those are the best ones. We are started loading somewhere and along the lines...we've had things that made us scratch our heads...some of those were even self induced.

Now get to shooting...go buy some powder and start burning it. Good luck.

So ultimately, what was the resolution? I don’t understand your update.

Throw that Hornady OAL tool away. It’s so inaccurate. Smoke a bullet or sharpie it. Or better yet, remove your firing pin, ejector and extractor. Load long, and move the bullet back a couple thou at a time until the bolt handle closes effortlessly.

A lot of heartburn could have also been saved by simply asking your gunsmith for a chamber print of the reamer specs.

Im not sure to be honest. i was getting short measurements and rounds wouldnt chamber. i was tapping the buttstock on the ground often because bullets were staying in the rifling when using a oal guage. dont know if there was a piece of shaving or trash or maybe a bur from the chambering but all of a sudden the issue was gone. i dont own a bore scope, but i did seat a bullet into a case colored them both completely with sharpie and chamber it and the only marks i had were on the ogive where it was just kissing the lands. since then i have ran almost 200 rounds through it and havent had an issue. i also threw the oal guage away and i just use the loctite method from here on out. i like it better. its repeatable, and accurate.
