Anyone use n570 with the 133-135 bullets? Had a load with Rel 26 but haven’t been able to find it in over a year.

In my 25sst*
Couldn't get enough 570 in to hit pressure.
61 grains i think, 4 years ago.
Currently running 59.5 gr of vhit n565 with zero pressure, 24" proof, cci250 135 berger. At 3150

I have ran up to 66gr(starting to show pressure) in my 6mm Saum with 115 dtac. I have long ass freebore so bullet robs minimal powder space. Have also used it in 65 Saum with 156s, 61.5gr was 3090fps, no pressure. In the 25, depending in you're freebore, I'd start around 60-61gr.
@NICETRY what's short cut? You referring to N568? I have found it vastly different in energy/gr than N570. Notably less velocity, but cooler burning. Higher case fill VS N570 on a fps scale. Tried it in 300norma and 257wby sized 25ca wildcat.

H4831SC or short cut. I have a friend who ran SC in his 25 SAUM with 131 black jacks and got 3400fps and it’s what he ran in the Nightforce ELR match a few years ago to take 3rd place I believe. I run RL26 in my 25 SAUM and it shoots great at 3340fps.
4831sc in a 25saum at that speed is either a 32" pipe or running 75k psi. My 25saum was around 58gr rl26 and 131s were moving right around 3300fps.
The 131 was a great bullet, wish the Blackjack guys could kept it all together.
Thank you gives me an idea on a starting point
I’ll 2nd this, this was my load exactly and roughly the same velocity
