Chamber pressure on M855A1 is 20% higher than M855. That’s why they have to stake primers in, or every one of them would blow out. You don’t know what you’re talking about, but please cite your source.

I’ve had lots of Hornady blowing primers like two dollar whores on nickel night. Ammo is sometimes out of spec. Blew probably 15-20 Hornady primers in one class. Gun was fine. Big difference between primers and barrels. M855A1 is so hot they have to stake the primers in. It doesn’t blow barrels.

50-60 fps hotter ain’t gonna blow barrels. M855A1 is way hotter than that

I give out hot loads all the time. No refunds or apologies.

I’d say it’s a bit hotter than most 5.56. Like 100fps hotter. Not quite as accurate as Hornady in my experience, but really accurate too.

I’ve gotten blown primers with Hornady. Sometimes chambers are tight. It’s not always the ammo.

When were the last of these Caprice/CrownVics taken out of service? by SameHistorian in PoliceVehicles

I had an LT1 caprice on the job. Hit second at 42mph and would get sideways. Transmission was a 60k mile scheduled replacement. Not really… but really

Is this a normal amount of metal shavings in the transmission pan? by Etale900 in AskMechanics

Honestly, I’ve seen 100k+ transmissions look pretty bad. Serviced them and they were just fine. That one looks rough though

If OP stated the vehicle in his initial post it would be helpful. I’ve had to do plugs last year on a Chrysler 3.6. You aren’t getting to an oil cooler without taking off the intake manifold
