    Need starting load suggestions for 6mm 284 with a 12" twist.
    Probably be using 60-90 gr bullets.

    Samspade ,
    Here are some loads that I use in my .243 AI which should serve as suitable starting loads for your 6mm/284 which has more case capacity .
    46.5 gns AR 2208 (Varget in the USA) with 55gn Nosler BT gives me 4030 FPS and is my most accurate load . 5 shots in the 3's .I can get up to 4200 fps without pressure signs with 48.5 gns AR 2208 .
    42.5 gns AR 2208 / Varget with 70 gn Nosler BT . This gives about 3550 fps and I use for fireforming . I can get to 3700 FPS safely .My manual lists 42 gns as maximum in the 6mm/284 with 70 gn projectile which I can't work out .
    42 gns AR 2208 / Varget with 75 gn V Max for 3520 FPS . Mild but accurate in my rifle .
    49 gns WXR with 87 gn V Max . WXR is I believe same as RL 22 but sold by Winchester .This is maximum in my rifle but 50 gns listed as a starter for 6mm/284 in my loading manual . .
    Have tried other powders but these 2 work well and give good velocity / accuracy . Suggest Varget will be hard to beat for projectiles up to 75 gns .
    My loading manual suggests AR 2213 SC (sold in USA as H4831 SC) is THE powder for the 6mm/284 .
    Starting loads :- 54 gns with 60 gn projectile , 53 gns with 65 gn projectile , 52 gns with 70 gn and 75 gn projectile ,49 gns with 87 gn projectile .
    Maximum loads for AR 2213 SC are up about 6 - 8% on those listed above
    Good luck . /ubbthreads/images/graemlins/smile.gif

    I've got one with a 1/14twist barrel and have only used 68br bullets. I use is H-4831 good place to start is 52 to 56grs. I know Hogdon has loading on the 6x284 may want to look them up on the net. Well good luck.

    For bullets 80 grains or more I would use R-22 or IMR-4831, IMR-7828. I would start at 50 grains and work up from there. For bullets less then 80 grains I would use IMR-4350 R-19 or Varget. I would start at 45 grains and work up from there.

    Aussie, What manual are you getting this loads from? WXR is the same as RL22?

    My best loads for my 243AI are 70gr bullet- 43gr of H4895 and 85gr Bullet - 42gr H4895 but that is with a 22" barrel.
