[QUOTE="Deleted member 46119, post: 936271"] I'll put my 2 cents in as I have hundreds of coppers down range. [LIST] [*]You have to use a lighter bullet for caliber making it harder to reach the same BC as lead. [*]Copper is just not going to as far for weight as lead. [/LIST] Accuracy is not an issue if you go faster and lighter. I haven't developed a 'rule' yet comparing mono weights to jacketed lead for the same use. I think I need a lot more data. Darn, more shooting. Example: My 1/12 twist Weatherby Mark V in 270 Wby barely shot jacketed lead 130's. Before Barnes published the load, I decided to figure out what 95 grain TTSX would do. Turned it into a laser. I easily got near 4000fps but accuracy was at 3668fps. "Flat" to 400 yards (no hold adjustments) with +1000lb of energy at 400 yards but it starts to fall off quickly after that. Fine for lots of game. [/QUOTE]
