H4350 should have no problem running mid 2800s, N555 same, but with more case fill. Pretty sure H4350 had me close to 3000 at psi with 135s in a 28" barrel.

It gets me 2,800 FPS with 133’s from a 20” barrel, and still puts down 0.4xx” 5-shot groups. I’m happy with that.
That’s money. I’m running a 23 inch barrel so curious to see what it will do once it has 100-200 round through it.It gets me 2,800 FPS with 133’s from a 20” barrel, and still puts down 0.4xx” 5-shot groups. I’m happy with that.
I removed the first 3 shots from the measurement, as they were cold & clean bore. But the rest of them were all factored in.
Run a dope chart for fun with the 133 Elite Hunters @ 2800. It’s absolutely incredible.
Which solver are you using? I have three I think and none of them have the 25cal projectiles preloaded so I’m having to put all the specs in manually and it’s a pain in the ass lol
You might have to manually input them, or use the one on Berger’s website.
What elevation are you using?
Just bought 500 of the 133’s from Ryan Pierce and still have a 20” barrel and action so debating between a 25 creed and a 25 PRC. Hunting rifle
Dude, the easy button is .25CM using Alpha brass and a nice set of Redding Typse-S Elite bushing 6.5CM dies (P/N: 60446). Just order a set of Short Action Customs .281" bushings, and swap the 6.5mm seating stem out for a Redding .25 cal VLD seating stem, and you're done. Simple as that. Shoot that barrel over to the guys at Blue Mountain Precision in Utah, and let them spin it up, they did excellent work on mine.
New video is up with the custom Aero/Proof .25 Creed and the OCL Hydro-S 6.5mm shooting 3" steel gongs at 300 yards.
4DOF and AB have them. My kestrel and 4dof are very close. Both are custom drag curves. 4DOF axial form factor is at .98.

I ordered 131s 9/7 and have yet to get them. Thanks for the reminder
Well, no, but that's not comparing apples to apples for my setups. From a 20" barrel my .25CM with 133's is averaging about 2800 FPS MV. And from a 20" barrel my 6.5CM is pushing 140's at about 2780 FPS MV. If you run those numbers with the same conditions (750' elevation), distances, etc... The .25CM beats the 6.5CM by a small margin.
.25CM w/ 133 Elites...
6.5CM w/ 140 Elites...
So, I guess since BlackJack went under, Sierra is just going to re-utilize the tooling for those 131 ACE bullets they were making for them, and rebrand them the 131 SMK's?I ordered 131s 9/7 and have yet to get them. Thanks for the reminder
@XTREM HTR16 You can play with the numbers all you want over on the Berger Ballistics Calculator...It's free.
