very accurate and no pressure signs.
That’s a nice load. My 300PRC is on its way back after 5 month hiatus at LRI getting some upgrades done. I’ve got to try this one out for sure as well as the one above. I just need to score some N570 now. How temp stable is N570?

What research I’ve done its very good on temp stable. farest I’ve shoot it is 700 yards with the above load and it was very consistent. 500 yards well below 3 inch group consist.
very happy with turn powder.
I tried h1000 but n570 out shot it.
never tried rl 26

this was on a 25 inch barrel with 10 twist. 4 groove hawk hill.

.035" Jump
This load shoots .25-.3 moa at 3005 FPS in the custom rifle I bought from 8andbait in the classifieds.
I think I might be in love with it.....

On another note, I worked up from 74.0 grains and it shot roughly 1.5 moa until 80.0 gr. the difference between 79.0 and 80.0 gr was magical. Not sure why but I am happy with the end result.

Also, the same load with 210 LRAB shot around .5 moa. They were both .035" jump, but the accubond COAL was slightly longer. I can't remember what the COAL or CBTO lengths were off the top of my head.
