Need help with pressure problems

[DUSTY NOGGIN]

I don't have one of those. First picture is new unfired. Second pic was the stuck case that had to be tapped out. I know my measurements are not exact as your device but I think mine shows something

flip any handgun spent brass 9, 380, 40 case upside down and use in place of the hornady comparator ,

out of all the different prices there are to choose from , this one is my favorite !!! FREE

Not sure how to go about this.
I'm a retired LEO and happen to have picked up a truck load of 40 cal brass when we would qualify with duty ammo. I got plenty of 40 brass.

 

[DUSTY NOGGIN]

put the mouth of the 40 brass onto the shoulder of the 264 , and measure head to head -- doesnt really matter what the overall measurement is , since you are only looking for the differences

a once fired 40s&w or 10mm is the closest diameter mouth which is very close to actual datum measurement (.420)

Primary extraction could be the issue. I hope Rem will figure that out and fix it.

Mud my brass was 2.502. Would 2 thou cause this much issue I'm not sure but don't think so.
I will report back once Remington looks her over and follow lances recommendations.

Yes, you never want your brass to be long. Max SAAMI length is 2.500", so I would try trimming your cases back to 2.495 or so, and shoot one or two to see if it helps. If not, you have other chamber issues.

So today I followed Dusty's lead and used a 40 cal piece of brass.
New 2.971
Fired 2.978
FL resized 2.977–2.980
Stuck case that had to be forcibly removed 2.986
Stuck case was also ruptured at the belt area forward

 

[ShtrRdy]

Is the 3.986 a typo?

Is the 3.986 a typo?

That has to be a typo.

Get new brass another brand when you get it back

 

[ppoole]

Just saying a common denominator with a lot of people and load/pressure issues myself included is Hornady brass.
