[QUOTE="J E Custom, post: 1495957, member: 2736"] Extended free bore can be your friend if done right. Free bore can lower pressure and increase velocity, Especially in the large over bore cartridges. You can have two much if the wrong bullet is used, but generally if you load to mag length allowing the bullet to jump a little before it engages the rifling lowers the initial pressure spike making for easier engraving of the bullet. All of my wild cat designs have generous free bore and have exceeded Velocity expectations with lower pressures. Accuracy has been very good with all of these rifles. Just My experience J E CUSTOM [/QUOTE]
