[QUOTE="7mmShooter, post: 1106418, member: 81795"] Hi guys, I've seen most running the heavier .375 CE solids are running gain twist barrels (12" to 7.25" seems most common). I just ran the 425gr CE MTH .375 cal in Berger's Twist Rate/Stability Calculator, and at 2700fps at sea level in 0* temperature with a straight 8" twist rate. its pulling 1.93 SG stability... I just ran it at 2700fps because I believe that's what would be seen out of a 375 Allen Xpress running a 32" barrel. Any thoughts guys? As far as I know Bartlein is the only one doing Gain Twist Rifling... Being able to run them in an 8" twist certainly opens up more options for barrels. Hell, from the few calculations I've run in JBM, the 425s in the Allen Xpress would run pretty close with the 352 MTAC Desert Tech Munitions .375CT factory load. [/QUOTE]
