I run a 300 weatherby a customized Montana 1999 action with a 1-10 barrel....

I’m dropping 3 into a quarter no problem With a 152 hammer hunter...

77.5 IMR 4350 with CCi 250 primer... Consistent and stable around 3225 FPS average...
Does this barrel have the Weatherby Freebore ?

No, It is a custom build with Montana 1999 action with a 25" kreiger barrel (no brake)... 1:10" twist. A little freebore, but not as much as weatherby factory. Very traditional rifle, custom wood work. Always shots lights out...

I’ll try that too, I usually go by the Nosler book, shows the most accurate powder too
I use IMR 4350 w 150 gr Partitions in both my MK v and LaserGuard, both shoot .5 @100 yds 3370 fps. Both shoot 165, 168, 180 gr under .7. Several powders work well...H4831, I7828, going to try some US869 next. Both are 26" w/mb's.
