  1. I want to reload 58 grain v-max for the 6mm ARC, to be used in an AR-15. Any suggestions? I currently have a 16″ barrel chambered for the 6×45, and want to rechamber to the 6mm ARC. The barrel is a 1/10 twist.

  2. Most experts are recommending at least an 18″ barrel with a rifle length gas tube. Some say barrel length
    + 1″ on the tube. The twist should be 1/7.5 for the best accuracy and bullet stability. A 1/10 is too slow a twist rate.

  3. PS: Hornady has load data on their site for bolt and gas guns. Best ballistics come from 100 gr – 108 gr bullets.

  4. Lance,
    I am not sure that would be a good thing. The 6mm ARC is designed for the longer high BC bullets making use of a twist rate of 1:7.7″ give or take. A 1:10″ twist rate would leave too much on table for this round.
    There are many barrels out there reasonably priced. I think a better option would be to save your 6/45 barrel and just buy a 6mm ARC chambered barrel. Who knows, one day you might want to jump up into the 90 -110gr bullet weights where this cartridge really shines and with heavy bullets the 1:10″ twist rate won’t work well for you. You can then get this new barrel in the length that you want or think you want.
    Just my opinion. Have fun!

  5. Rechambering 1-10 twist barrel is a waste of time. I have 3, 6 MM ARC rifles. Best accuracy rifle +1″ with a 1-7.5 twist Proof Research stainless barrel, all barrels are 18″ and 1 inaccurate 1-7 twist BA barrel for fire forming. The Proof barrel shoots 55 grain to 115 grain accurately. It was so good I purchased another. The 6mm ARC is best with heavier bullets, I use light bullets for fire forming cases. I like l08 gr. To 115 gr. the heavies, the best…that’s what is was designed for high BC long range bullets…might as well use a .223 if your shooting Iight 55 to 68 grain bullets as they have poor BC for short range or short range varminting.
