Haha I've had that happen too with rl25 in a .300 win mag. I forget what I did wrong but I made an honest to goodness mistake somewhere when I was younger and just getting into this. But before I even attempted to open the bolt I knew something was very wrong because of how hard the thing jumped and kicked me, and the SOUND. That's one thing I do wonderā¦how ungodly deafening is this 7 back country going to be out of a 16-20 inch pipe if you DONT have a suppressor? I imagine it will be dreadfully concussive.Yep, the big question will be how much the charge mass is Increased with the pressure increase, and if the charge velocity skyrockets with pressure and eats up the recoil advantage.
Anecdotally, with something like rl26, I've seen a HUGE recoil increase as a pressure sign. How much pressure was I running? No clue.
Some day I will tell you the story of what happened to me, my MKV, 300 WBY and 180 TTSX and why I WILL NOT TRUST BARNES reloading data EVER again.YOU KNOW WHAT ELSE IM WONDERING?
Now that I've confessed to one of my early days reloading failuresā¦
Do y'all think this cartridge will require entirely new primers with way thicker cups and heavier firing pin strikes to light them? Because man, all the primers I've used sure don't look too happy when you go much above 65kpsi, heck some of them get "dramatic" in their appearance well under that limit.
If this ends up being "special dies, special presses, AND proprietary specialty primers" I'm out!
I've done That.Haha I've had that happen too with rl25 in a .300 win mag. I forget what I did wrong but I made an honest to goodness mistake somewhere when I was younger and just getting into this.

Anyway, when I looked at the chrono and saw that my weatherby vanguard 300 win mag had spit a 180 grain Nosler ballistic tip out at 3460 feet per second I knew I screwed up big time. Had to open the bolt with a mallet. Primer blown out the back, brass was toast. Also broke the cheap bushnell scope it came with inside.
But if the bolt doesn't seize up that means you're still working up, right?I've done That.
300WM, 180 Swift Scirocco, RL- 25.
Alliant Powders manual, years back there max load data Was definitely MAX.
My gun did what you described but it didn't lockup. Model 70
Definitely Got My Attention.
