[QUOTE="GaryJones, post: 64799, member: 3690"] [b]Gain twist rifling - pro\'s and con\'s[/b] Anybody ever try gain twist rifling (like the new .460 S&W pistol cartridge)? Seems like a way to reduce chamber pressure by starting with a 1:12 and taper to a 1:8.5 and still be able to stabilize heavy for caliber bullets. Would it be possible to taper for 3/4 of the barrel length and then run the rest of the way out at your desired twist rate? [/QUOTE]
