I'll give him a call on Monday. What is your COAL with a 215?

Granted there might be some slack in the Hornady comparators - but I would be surprised if it is that significant. My COAL to the lands according to my Hornady OAL length Guage and modified case is 3.465 with the Berger 215

After reading this thread, you guys got me thinking about my own 30Nosler which was built off a Rem 700 mag action. (originally 300RUM)
I just started to load some 215s which I could never get before. My CBTO measurement with the Berger 215 just touching (using the Hornady tool) is 2,840". What would that make my freebore?
Bullets loaded .020" off just fit into the magazine. None have been fired yet.
FWIW = bbl has 385 rounds down the tube.

A heck of a lot longer than mine haha. Mine is 2.697 cbto just touching.
I would say I have SAMMI, but I think I'm even below that
Could be a bad reamer. Anything can happen. All I am saying is their is less chance of that happening than the $300 worth of measuring tools most reloaded use. I am sure they make reamers on cnc machines as well as chamber with them which are far more precise than anything you are using. Have you checked your calipers against another pair?

Yep totally agree.
I'll check my calipers now - they are brand new Mitutoyo ones, I'll check them against my old reliable dial ones to make sure haha.
I'm just frustrated because I literally just got this gun after 7 months and now this happens and I'm sure I'll have to send it back.
No matter what I would shoot it first. I wouldn't get wrapped around the axles before you even shoot it. I am sure if you call Alamo they will tell you the same. If I remember correctly you were having this built for an accurate 500 yard rifle. You haven't shot it yet to see what it does and you are talking about sending it back. It could shoot 1-1/2"-2" groups at 500 and you would never know. Call them amd let them know what you are seeing they will work through it with you.

I just checked with my smith and his 30Nosler reamer has a .145" throat. I've probably got a bit of throat erosion to add to that.

Just ran a quick pressure test with it and here are the results.
I do think from seeing this that the rifle will be a shooter. There wasn't a ton of change there between nearly
I also noticed that almost all of my cases had a slight extractor mark - even the lowest powder charge - I attached some pictures. Is this normal? I actually think I got this mark from just clambering it because I loaded one and did not fire it and ejected it and then still got the mark.

82.5 to 83.0 looks nice. Did you get a sticky bolt or click at the top?

I did not. The only thing I noticed was the marks on the brass in the picture above. But like I said, I could get those even before firing
