If we are all truthful with ourselves, For the right deal, there aint one out there that I wouldnt own.As long as its legal to own it. BECAUSE WE ARE ALL GUN WHORES!!!
And I am particularly a rifle nut, and I agree. There are plenty I will never buy or own but that doesn't mean I would not own them.
If we are talking about hunting or defense, there are plenty I would not want to use, but again, if the situation was bad enough, I suppose I would use any of them if nothing better was close to hand.
I own calibers that I don't like. I don't like 5.56/.223, but I own 3 of them. At least I did before I sank that boat on lake Oconee.
