What is the Best Barrel Length?
Different shooters have their preferences, but here are some general guidelines: 100/200 yd 6mm Benchrest Gun: Use a short, 20″-24″ barrel. 22″ is ideal, but you may want to start with 24″ so the barrel can be set back as the throat wears, or if you want to convert to a different caliber (i.e. from 6BR to 6PPC) 300m to 600m: A variety of lengths will work here, but you will probably be shooting heavier bullets, with a slower-burning powder, so you want a longer barrel that will give you more velocity. We recommend 26″-28″. However, barrels as short as 24″ do just fine at 600 yards with the right bullet. 600m and Beyond: Go with at least 28″. A 30″ length tube may be even better, but with some powder/bullet combinations, you may actually get less velocity with a barrel much longer than 29″. With a standard 6BR case, 28″ is probably long enough, while a 6BR Improved case can give a little more velocity with a 30″. But keep in mind shorter barrels will be stiffer, if they are the same con
