I had pac-nor make a barrell for my savage mbvss in the 300 wsm chamber. My obsevation is and I am new at this is that my loaded cartridge overall length from case bolt face to ogive is now 0.090" shorter than the factory barrel I removed. I no longer have the case capacity that I did have before. I was shooting H4831 @71.5C with the nosler 180 accubond and it shot .4 grps at 100yds. Has anyone run into this situation before? My other question is has any one been shooting the Berger vld bullets in the 300wsm and if so what wieght bullet and powder manufacturer and grains of powder and primer are you using and with what results. The pac-nor barrel I have is the super match 28" polygonal rifling tappering from 1.020" to 1.050" at the muzzle. Thanks for any information you may have.
