Why won’t my bolt close?

[DUSTY NOGGIN]

the creedmore is known for its oversized EGO .. i bet its getting caught from having too big of head .. i bet if you belittle it .. tell it its just a short action non magnum .. it might just fall right into place

but on to the stuff that matters , id smoke your brass try to chamber and see where it making contact .. youll know what needs done

At some point brother you are going to have to full size it and bump the shoulder there is really no way around it. 90% of the reloaders I know that just neck sized have since switched to FL bushing dies. It seems the entire just neck sizing thing is something from the past.

I drank the FL sizing/Redding bushing die cool-aid 3 years ago and my reloading life has never been better!

I may have to get in the cool aid line for this particular rifle

Now that sounds like a plan!

If your not FL sizing correctly after every firing your leaving potential on the table!! All neck sizing does is make every firing different from the next which is not the best.

That is correct. There will never be anything more accurate than properly setup FL die when all brass is truly fire-formed with correct shoulder bump on every case. Now that is consistent!!

Yeah, give it a try. I was always hung up on neck sizing because for some reason my Cooper rifles tolerated it well, but I got over it when I started to buy better quality brass (Lapua & Norma) and watched a few of Sam's videos on YouTube. I don't anneal or anything like that and I'm still getting about 12 cycles on a piece of brass even though I may be "working it hard" by FL resizing. There was no perceptible difference in accuracy either. I once read that neck sizing can be hard on the action too (bolt- lug recesses) but I don't know if this is true.

Lol Its certainly hard on bolt handles when you snap them off trying to pry your action out of battery like ive seen 2 people do and heard of several others.

Yes I know you need to F L after 2-3 firings, which I do. Guess I must be the only one neck sizing these days. Thanks

A bit long but Sam did an awesome job with this video ...

sounds like u need to get a case gauge and bump the shoulder back .002-.003

Im shooting a Bergara B14 HMR in the dreaded 6.5 C M. Load is 143 ELDx, 41.5 gr. H4350 CCI BR2 primers, Hornady cases. Seated .015 off the lands. Here's the problem if I neck size a fire formed case the bolt will not close on about half of the rounds. I neck size everything except 223 and have never ran into this. Any ideas, suggestions. Don't really want to FL size if I can keep from it. Thanks!

I'd invest in a "bump die", set the shoulder back .001, seems to work for my bench rest friends. Now if we can just get them to learn to shoot with a sling off the dirt, they may turn out to be riflemen.

I agree with all that responded! F L size and then check O.A.L. Trim if nesessary and then load the shell. Do one and if it works that was your problem!

You need to FL size. Plain and simple.

This is the holy grail as far as I'm concerned when it comes to what to do with brass. https://www.greenhomefair.com/lyman-300-wsm-case-length-headspace-gauge/ i know this isn't the right caliber gage but it is the tool of choice. if the brass doesn't seat in one of these or sticks out past the end you have to take corrective action or the rounds won't chamber properly. I full length size even new brass.
