Bolt sticks at the top of the stroke before primary extraction because the brass is stuck in the chamber. The bolt makes a "click" sound when you apply some pressure and force the bolt open.

Started getting them with my 284 right before I swapped to my 7 SAW barrel. Quite annoying.
What hunting crowd? Define these hunters by Social Ecconomic Class! You do not have any poor working men hunting to put meat ont he table asking you to do 7PRCW.......You have some rather wealthy clients that hunt for fun asking you to make them expensive toys for that endever!
Let's call a spade a spade. I do not want young hunters and average shooters on this sight getting the idea that the 7PRCW is all the rage and a must have for hunting deer and elk in their back yard!
Just like your skiers that take a helicopter to their location are not your average skiers! The guy building a 1500HP LS is not your normal working class guy building up a daily driver in his garage!
I know these sorts of hunters! They wear work boots and drive big trucks but their hands are as smooth as a 12 year old school girls. They hunt becasue they grew up doing it but they have never missed a meal in their lives! Not hunting would not effect them or their children in the leat. Calling these sorts hunting types is just plain wrong. Nothing against them I am sure they are great people. The brain surgeon that fly fishes to a metronome is not the same as the guy working 3 jobs that is shrimping in the moon light or digging clams before bed to feed his family. They guy shooting Elk with a bipod and Arca rail at 1500m+ is not the same as the guy that stalks to within 500m to shoot his Elk. One is actual hunting the other is playing an analog video game!

This takes full of yourself to to an Olympic level.
A barrel and dies isn’t all that expensive and that’s all it takes.

I chamber all kinds of cartridges for hunters. Many hunters also enjoy other hobbies, playing with custom rifles is a hobby that meshes with hunting. I enjoy both and my favorite part of hunting is preparing for it. Tuning the rifle, dialing it in, scouting my spots, ext. I dont enjoy the kill or the work after, but I enjoy the clean organic meat. To think any one is hunting or gathering to feed their families today is a stretch. If things are that tight that your on the verge of going hungry, time would be better spent at work than out in the field. People hunt today because they like it for one reason or another. And more power to the guys that worked harder and smarter than me to make themselves a better life. Dropping out and working labor jobs wasnt my best move.

On another note, I did release these reamer prints through JGS. But I changed the name to 7-6.5prcw. You guys will see why soon. I have a turn and no turn available through them.

Wow take a breath. I'm a working guy , and Alex built me a hunting rifle a couple years ago ( I call it Dracula) best gun I have ever owned.
Nobody hunts to save money- elk meat costs about $100/LB IF you shoot one every year. I haven't been versed in the condition of 12 year old school girls hands, well since I was 12...

Does anyone know what Cortina's .200 line dimension is for his die? Wondering if I should order one. Using the bullet central die is sizing down to .532.5 from .534 and starting to get clickers after a few firings. Feel like it needs sized down some more. Moderate charge of H4350 @ 2910 FPS.

I don't have any experience with the Cortina dies but for reference here is what I got with the SAC die.
6.5prc sizing die dimensions/clickers
I am starting to get clickers with my 7-6.5 PRC brass. I have my reamer spec at .535" to add extra clearance at the .200" line to prevent clickers. Fired brass measures .5342" at the pressure ring. Sized brass measures .5332" at pressure ring. I believe my sizing die is not sizing enough...

EDIT: Apologies, should have read more carefully. .535 is chamber not die. Not very useful to the question….

Awesome. Has this corrected the clicker issues for you?
I wish I could say one way or another. But I haven’t had a chance to test for clickers.
And the numbers in that post for the sized brass with the SAC die, is with brass that I was getting clickers with. Not with once fired brass. So it may size even more with once fired....

The issue with this case as well as others like the saum and wsm is the new brass is extremely tough. You have to squeeze it hard to get off the clickers. Then as you shoot it the case head expands. At some point the case head starts to swell the base of the die. When this happens you cant make a die that works. I had an idea about how to make a die that wont do that and had Erik make me a few. It worked. That design is in his dies. I told bullet central about this years ago in an attempt to fix the prc cases, but they never tried it. I believe Erik is also going to offer a small base option as well.
I'm hoping it's a touch smaller than the Bullet Central resizing die as I am experiencing the same issue in Australia. Recently received a custom reamer from JGS which I specified at 0.5355 at the .200 line and after 4 firings running ADI2209 (H4350), at average velocities (it has shot best around 2830fps so far running 184gr hybrids, and working up to around 53.4gr which is giving me 2865fps, I've got clickers...FYI below for anyone else out there experiencing this problem:
At the .200 line (measurements taken with an electronic EZ Data iGaging micrometer):
JGS custom reamer with the .200 line marked as 0.5355
- Virgin Lapua brass measuring 0.5300 at the .200 line and neck turned for a .315 neck
- Once fired brass measured 0.5332 - no clickers, extraction smooth as silk
- Resized with the Bullet Central die 0.5320 (shoulder bumped back 3.5thou to account for shoulder bump back (all brass annealed with AMP annealer after every firing)
- 4 times fired is measuring 0.5342 - clickers...not too sticky, but definitely clicking - the unknown here is that I don't know if this number will expand with additional firings
Now it rechambers fine and the clickers aren't extreme, but they're definitely there so based off what I'm experiencing, it looks like with fired brass whereby you have 2 thou clearance, you're sweet, but once it's been fired several times and expanded a touch more, it looks like the clickers start creeping in once you're under 1 and a half thou clearance from your reamer spec. Based on what I'm experiencing, I'd be inclined to take the reamer spec out to 0.5365 - I think the extra thou is needed with this cartridge and finding the right sizing die is proving to be a challenge. The Bullet Central one cost me AUD550 and Erik's is costing me a touch more with shipping, but it has other features which I think are worth it.
I don't think Erik's dies are shipping yet, but I can't get my hands on it quick enough at this point as I really want to make a successful go of this cartridge.

The BC die is speced smaller than the virgin case head. You cant go smaller. You may want to measure your die to see if its out of spec.
