    2 to 3 thou is enough for bullet release
    Get your bullet close to the lands
    65 grain v-max usually works great in 6x45
    Try a stick powder like h-322 or 8208
    6x45 can shoot under moa with right load
    My 6mmAR shoots half inch and so can a 6x45
    My bhw 264lbc shot 3/4 inch and I sometimes wish I didn't sell it

    I measured the fired case necks where the bullet does not fit and they are .265", the same as my reloaded rounds with a bullet inserted.

    I then thought to measure the case necks where the bullets do fit and they are .270" to .272".

    The fact that some of the necks are .272" mean BHW made the barrel correctly.

    I think what is happening is with starting loads the brass must be springing back to the resized dimension.

    Maybe the case necks should be annealed.

    These are all O.D. dimensions.

    I'd try 26.5 grains 8208 with the 65 grain v max.
    If it doesn't shoot well I'd be surprised.
    It's a favorite load for coyotes and fur friendly.
    There's 16 pages of 6x45 information on the predatormasters forum.
    It's a good read for 6x45 shooters.
    I never had to clean my BHW barrel much.
    They don't fowl easily with their poly bores.
    I wouldn't use JB paste since the rifling is shallow.

    Shoots lights out in my 18" BHW HB and is my go to coyote load.

    + for swaging the primer pockets. Depth is uniform plus you get more strength in the pocket area then if you ream it, IMHO. I have not lost any cases because of loose priming pockets. I also anneal. Agree on the easy to clean poly barrel. Virtually 0 copper fouling. It's a great caliber.

    454bore and 37L1:
    Thanks for the comments.
    I put about 3 patches with JB paste through the bore. I will not clean often.
    I did read some of Predatormaster forums on 6x45. I didn't realize there were so many pages of info.
    I plan to get some XBR-8208. I will order the primer pocket swager.
    I posted earlier in this thread where I did shoot a 5/16" 5 shot group at 50 yards so I thought this is easy.
    Not so easy.

    Got my barrel in and gas block on last night and just need to put the handguard and VG6 6.5 on tonight and load up 50 or so 70 gr Varmageddons with 24.5 gr of XBR for a function check and break in. Hopefully that will occur tomorrow afternoon weather permitting.

    It sure looks slick looking down a shiny new 24" 3P BHW barrel. Thinking more and more that I'll get past my 2900 fps expectations with either XBR or Benchmark
