It's an ammo factor, not a gun factor.
Not popped primers, but dropped or lost primers.
Not an issue of high pressure, just an issue of them getting knocked out from the force of the case hitting the ejection port/brass deflector and light staking/low retention force on the primer.

Hornady seems to be hit and miss. I have 6 loads on some 7mm RM with no issues. Second batch had a split neck second firing. None of the loads were toasty either.
Pappabear, I'm hoping I'll be jumping on the 6.5 CM train this year and want to run my MWS as a dedicated precision rig. I'm tracking you're able to consistently hold sub-MOA groups with some hovering in the .5 MOA range with the stainless steel barrel. Did you observe that type of accuracy out of the box, or did you go through a break-in ritual before seeing your groups tighten up? I've contemplated going the custom route, but honestly I don't want to put that much time, effort and energy sourcing components, a capable gunsmith and paying for all the work if I can get consistent sub-MOA accuracy out of the factory barrel. I'll be more than content with consistent groups in the .5 to .75 MOA accuracy range. Also, are you reloading exclusively or are you also running off-the-shelf match ammo? Have you found a preference?

We have done no reloading for the 6.5 and even decided that cheap factory ammo was so good that we are only going to reload for my Bergara 6.5. Yes sub Moa right out of the gate with my MWS barrel. I have shot S&B cheapola ammo, American Gunner 140 BTHP and very good Hornady 140 ELD's. All shot MOA with some sub Moa.
We focused on chrono and my 6.5 Bergara today. The S&B shot .75 MOA, American Gunner shot around .5 and Hornady shot .5 MOA. My MWS is not that much different. I left the chrono data with Mark, even though its a Bolt you can enjoy the data. Ill ask Mark to post velocities.
Just so you know the S&B is $11.00 a box the Am gunner is $150 for 200 rounds and the ELD are around $125 per round.
The S&B BC is horrible, we call it our 30-30 load but it has the highest velocities and can still make hits to 1300 yards from the MWS
Am Gun is a BTHP a bit slower but better BC
The ELD is the ELD
Bottom line, your MWS should meet your accuracy concern and also you can buy factory ammo and have a blast, on the cheap. No break in period or if do, it will get better. I pumped heavy round count with all this cheap ammo and a 20 round mag.
