[QUOTE="MontanaRifleman, post: 890172, member: 11717"] The biggest factor in what efficiency you get out of your barrel is the type and speed of the powder you use which will have a lot to do with the bullet(s) you choose. RL17 is a fairly efficient powder for shorter barrels (like 24") and is a great powder in the 300 WSM for a fairly large range of bullet weights on the heavier end of the scale like 165 and up. You will surely see more efficiency and velocity with longer than a 24" barrel. How much, I'm not sure. But if I were to build another 300 WSM, I would go for at least a 26" barrel. Now, if your priority is a good shooting short barrel (24") cartridge, the 300 WSM is a very good choice, especially with RL17. In my factory 24 3/8ths barreled 300 WSM, I got 3200 fps with 180 E-Tips and 2930 fps with 210 LVD's using RL17. Very good velocities IMO. With another couple of inches, I could probably have got another 50 fps or so. [/QUOTE]
