[QUOTE="J E Custom, post: 285995, member: 2736"] Most factory muzzle velocities are hard to match in factory rifles because they are tested in custom barrels. and are the highest velocity reached not an average of all shots fired. And most of the barrels are 26", most factory hunting rifles are 24". The only ammo I have ever seen that reaches or exceeds listed velocity is the factory Weatherby ammo in Weatherby calibres. If you have a slick Custom barrel they will make up about 50 ft/sec from the 50 ft/sec lost in a standard factory barrel, so they will be close to listed velocities. Always verify velocities with a good chronograph and use the average, if the highest velocity matches the factory that's fine but use the average for trajectory calculations. J E CUSTOM [/QUOTE]
