If you want a 300PRC then get one. EasyPeasy. You're going to get a bunch of people telling you to buy something else but if your asking for a opinion on the 6.5PRC vs 300PRC, and you have remorse over the 6.5PRC purchase, then get yourself the 300PRC. I shoot both and both are awesome performers. I think I've seen 10-15 posts of people telling you to buy something different but that doesn't answer your question. More and more brass is coming available for the PRCs now that Lapua and Peterson are making it. Ammo is starting to recover and I saw it on the shelf at a LGS 2 weeks ago for $53 a box. Anyways…. Good luck!
