6mm arc maybe not that versatile.

So I was all excited about the arc mainly because I wanted to use it with all the great 6mm varmint bullets since we fur hunt all winter here in ND. After reading on it a while, I realized oh crap the twists on all these barrels are gonna be optimized for the way heavy 6mm bullets. It was made for a military application, I get it but man I hope I’m wrong or that they give use some twist options so we can run light bullets to medium heavy bullets for deer. What do y’all think, will it work with the lighter pills with a 1-7.5 twist all the barrels seem to come with?

If your primary goal is saving fur then a smaller caliber yet may be your goal. Coyotes fur hunters that are really out to preserve the pelt are often choosing a 17 cal. 17 Remingtion historically has been the preferred tool of the trade w the serious coyote pelt hunters. 17 Fireball has been a somewhat distant second. From my perspective the primary potential flaw w the 17 cal in recent years is the lack of preferred bullets for pelt hunting. 25 grain and 30 grain HP w a fine target tip were the go to pelt hunters bullet of choice. Unfortunately the availability of these fine bullets has largely dried up in favor of the plastic tip highly frangible options more recently.

If all you wish to do is dispatch the coyote your options are many. If you are striving to save pelts then smaller diameter well chosen bullets may be preferred.
