RE: 7MM Rem Mag. Rifle Built - 24" vs. 26" Barrel?
Well 20-22 vs. 24-26 is 2 to 6 inches and in a an overbore cartridge like the 7mm Rem mag could be anywhere from 75fps on the short endto 300 fps ormore on the long end depending on each particular rifle.
A 350 Rem is a short action cartridge,holds about 10% less powder than the 7mm Rem, and has a bore diameter that is about 20% larger and is therfore a much more efficient cartridge than the 7mm magand does not needthe added barrel length that a 7mm mag would in order to achieve the velocity it was designed to achieve. So a 20-22 inch barrel in that particular cartridge would be a very acceptable berrel length IMO.
