Aside from restrictions to the specific divisions, the only limitations are on cartridge/caliber and velocity. PRS rules state the rifle must be .30cal or less, with a velocity of 3200fps or less. Velocity may be tested at any point during a match; there is a 32fps allowance for atmospheric and chronograph variances. Some matches may set more restrictive limitations such as a slightly lower velocity, or specifying .300 Win Mag as the most powerful cartridge permitted.
