Thread: FL resized rounds wont chamber

Always learning, struggling to get accurate seating depths the other day. I tried using my Lee hand press, which did a way better job. Reason the Lee hand press has a physical stop as my main press doesn't and is spongy, solution a piece of plate steel screw into postion so as the make a hard stop, so lever pressure is always repeatable. Helps to get rid of all the linkage travel and is very precise, 1 thou as where before they were ranging by 4 thou.

@chainsaw are you still up here? Ben is only 15 mins from you if do. I remember you were a godsend in finding out the issues with my 284s chamber

Yep, same place. Happy to lend a hand if needed.

Regards Grandpamac.

My rifle Remington 700 BDL has had a 24" True-Flite barrel fitted, sako extractor and has had some alterations to improve the feeding plus a few other things that wont be playing a part in this issue. i havnt tried my rounds in my friends rifle as he no longer owns a 7mm wsm , it is his once fired brass that he has given me but thats not important right now as non of that brass has been loaded up. its only my own once fired (from MY rifle) brass that has been used to make the rounds that we are dealing with.

I will attempt your suggestions this afternoon and report back.
Thanks

Try screw the die down till it touches the shell holder then screw down a little more this sometimes helps

One question will a sized unprimed brass fit in your chamber.
Like Grandpar said screw your die down at least 1 turn past touching the shell holder.
Than try and chamber with no primer.

@grandpamac i tried the steps as you described and the unprimed case did not fit

what does the fella who put the build together have to say??

I'll ask the question again. Can you corfirm that the case in pic one definitely fits and pic 3 doesn't?
If you have a case that fits a few measurements will tell you what the problem ig. eg an oversize web.

i bought the rifle second hand, i didnt do the work, it was carried out buy Hardy rifle engineering in 2016. its not the previous owners problem so i have no intention of bringing it up with him after owning the rifle for 3.5 years

yes you are correct. the round reading 45.86mm fits and the round reading 46.05mm does not.

Skip read to here so probably missed afew details. Of the two cases mentioned in this (above) why is one shorter than the other and why can't you make the longer one the same as the shorter one?
Forget about hornady headspace gauges. For a true bumped fit look up "wheeler method "
But that's stuff for further down the track also look up " cam over" on reloading presses.
The trouble you have is that the brass was fire formed to a different sized chamber to yours. You need to get it back to SAAMI specs....then shoot it in your rifle to fire form it to your chamber, only then can you start to "bump" your cases.

hmmmm I seem to recall a certain dog chasing member had a HUGE shitfight involving a rem 700 custom build..and the gunsmith mentioned also sounds familiar....lack of camming ability in 700s of that time being part of issue..... @mikee am I recalling correctly??/

OK that's good, you need to do some measurements with your vernier to determine the difference.
Is the measurement to the datum on the cases you are attempting to size still longer than your good case. ie has there been any change at all with cranking the die down futher?

yes i do, will have to get back to you with this, the over all length of all the cases are within spec its only appears to be the shoulder measurements thats causing me the greif. ill do some comparisons and take some photos and get back to you.

i dont think its a rifle issue as am able to chamber my factory ammunition with no issue at all, its far more likely an ammunition issue or my poor technique
