Is that a custom barrel Mallard or a factory offering..... I've been wanting to try a 1 in 7 twist barrel for one of the 243s
The barrel is a carbon fiber Proof Research light sendero 1:7.5
105 hpbt and H1000 from my 243 has been the real deal
How much h1000 are you using and what kind of accuracy and velocity are you seeing from it?
