[QUOTE="J E Custom, post: 1794071, member: 2736"] Actually the longer freebore improves the engraving starting pressure by giving the bullet more jump lowering the starting pressure and allowing more powder for the same pressure, ultimately increasing velocity, Some of the big Weatherbys have more than a half inch of freebore. If good quality ammo is loaded for these cartridges they can be very accurate. One of my most accurate rifles (A 30 x 378 Weatherby) will average 1/10 MOA. To date the best 5 shot group has been .092. Note: If the freebore is shortened, you may not be able to use Factory ammo because pressures will climb above max and blown primers are the norm. When loaded with a lesser freebore to maximum pressure velocity will also suffer (Go down). J E CUSTOM [/QUOTE]
