You should be way north of 4000 fps , last year on my load development for my 25/284 with a 25 in 1-8 twist using 62 grains of rl19 I was averaging 3860fps with the 90 gr absolute , highest vel 3876fps , settled on 61.2 grains for 3800 fps . Lapua brass , primer pockets still tight, It is a compressed load . I could not achieve that with h4350 before pressure.THE 75 grain hammers have my curiosity on how fast the 25-284 can push them.I’m honestly very curious how fast you can push those and I may try them.
