Nope. Her isn't. Mind you, I've never seen the 115's or 110's, Joe mentions for sale in any shop in Canada, but they exist. Berger makes a 115 moly coated VLD bullet too, but you need a 1 in 7 twist. Most .243's aren't.
Mind you, after seeing what a 105 SP does to a ground hog, the only reason I'd want a bigger bullet is just because I want to try them.
