Welcome; welcome; welcome.
Some say "The South will rise again". I don't know about all of that, but I can certainly say that Colo Spr is certainly rising in the number of folks we've got on this site.
.300 & .338; eh? You must really be a stocky person, don't like your shoulder, or just love to shoot a "mans caliber" rifle. Good for you. Personally, I've gotten to be too much of a wuss in my old age and keep the larger caliber stuff for elk season. The rest of the time I prefer a more manageable recoil cartridge like the 5.56/.223.
We've got a great group of folks here on the site with more experience and knowledge than you can shake a stick at. If you have any comments or questions, just ask (hmm, I think you already have!).
I've been trying to encourage all new members to check out the site Terms & Conditions (aka Site Rules) to help to keep you from making many of the same mistakes most of the rest of us have made. And, if you're not too opposed to it, *I* recommend adding your location (Colo Spr) into your profile so you don't have to consider it when/if you post an item in the Trading Post. Just a suggestion.
