Does anyone have any data for the balistics of commercial rounds such as 75 TAP coming out of SBR w/ under 14.5" barrels? I am interested in a build, but I don't know how much barrel length I need to ensure fragmenting. I know i need ca 2300 fps, but I don't know how many inches. Can anyone help? I am also interested in what what would be the minimum 308 barrel length for frag effectiveness w/ 150 grain 308 V-Max Round? |
