Article review is 5 years old, and Ruger has added (and subtracted) models. The 243 is no longer available (probably replaced by the 6mm Creedmoor model). Ruger also added models 6.5 PRC, 300 PRC, and Magnum models: 300 Win Mag and 338 Lapua Mag. They also offer several Rimfire models in 22lr, 17 HMR, and 22 WMR. I remember them also offering the Precision Rifle chambered in 223/5.56, but can't find it on their website. The 243 Win was offered in their first generation run (wish I bought one then), but by the second generation models, it was gone.
I have several RPR's, chambered in 308, 6CM, 6.5 CM and 338 Lapua. I'd like to eventually get the 300 Win Mag and look into the PRC caliber models as well.
Thanks for posting the article Anni, brings back memories of shopping for the RPR's, which was fun.
