My first was a TC High Plains Sporter in .50 cal...back around 1990 I think.
Sure wish I still had it, but I was young and dumb and traded it in on the first Knight I ever got, back in 1993 or 1994. A stainless MK-85 that I still have today.

Don't regret getting the MK at all, I just wish I had not traded the TC in on it. It was a nice rifle that you don't see much of these days. Heck, you didn't see em much back then.
