[QUOTE="MagnumManiac, post: 2394414, member: 10755"] The adage of longer barrel equals a slower burn, or a shorter barrel equals a faster burn simply isn’t true….to a point in the extremes of either. So, for example, you have your 7-08 with a 26” barrel and your buddy has a 20” or even a 18” barrel. The powders in the reloading book that give the highest velocity in the test barrel length, will also give your barrel and the shorter barrel the highest velocities per grain of powder. If you stick with those top 3 powders listed in most manuals, you should be good to go. In the wife’s 7-08, we use either H4350 or 760 at this point, very early on in load development and the bullet she likes is 120g thus far due to recoil of the heavier bullets. Cheers. [/QUOTE]
