This one is .243. I just now ordered some ammo for it from Cabelas!
It's the MCA model from the '60's. It had a monte carlo comb, but since I will likely never shoot it with a scope, I took it down and reshaped it properly for use with the sights. I do have the rings for it, and should I ever decide to scope it, I can make myself a leather comb riser.
I would LOVE to have an older one in 6.5mm, but they're rare and expensive (I don't think I've ever even seen one!) Not that this one wasn't expensive (at least to me).
I actually haven't shot it much, though I've had it for years. At first I wasn't actually a fan of the .243... It's so small and all!
but have been studying it and have since grown to be a big fan. From what I have read, it seems to be quite capable of effectively dropping deer, elk, even moose like they were hit by lightning. Some people say "it's not powerful enough", but I also hear people say that .30-06 isn't powerful enough, and they wouldn't trust anything less than a .300 magnum!
My sights are dead on in the 50-75 yard range, and it's a sweet little gun. Yes, the forward-positioned bolt handle is slightly more awkward than a standard Mauser type bolt, and you have to handle it differently, but you get used to it.
