inot expecting exact load measurements, but anyone got any good combos that work in there .260? so far i've used h4350, h4831 and imr4831. all are pretty even in the accuracy dept., but h4350 shows the best velocity. using speer 120gr. hotocors and nosler 120gr. bts i can get 3000fps with my 26" barrel, but i've had to back off the listed max load because i'm getting cratered primers. thinking about trying h414 and RL19 next. any info?
