Seems like the 37xc is catching on. Wondering when you might consider having Peterson just make a 37xc cartridge??

@Davidtubb 4 года назад

In the near future.

@@Davidtubb Has the future came around yet after 2 years? Is Peterson making the 37XC yet?

i have a brarrett mrad in 338lm and 308 win. looking to step up to the 37xc. i know a lot of shooters will use a 36 in + barrel. can i go shorter say 30 inches and still get good velocities? i think any of the change barrel platforms are great for this cartridge.[ mrad, AI, Desert tech]. purpose built guns in 37 cal may only get a few shots a year .

Can you advise on the ideal twist rate to run the 350g plus bullets in the 37xc please

@Davidtubb 5 лет назад

I have been running turned solid bullets at 1:7 or 1:8 twist. Jacketed/leadcore bullets need to be shot out of a 1:9 twist or slower barrel in order to avoid spinning the jacketing off of the bullet before it hits the target.
