There have beenquite a lot ofpowder & bulletchanges and additions since 1995, so yeah, I'd say it's a little dated.
Since 1997, a lot of new factory cartridges started hitting the market: 260 Rem, 204 Ruger,WSM's, WSSM's,RSAUM's, Ultra Mag's, and more. New powders and bulletshave been developed that are taylored to some of these new rounds. And of course they work with older cartridges also.
