I'm a shooter, not a collector. For me, a rifle that cannot be fired has no value. That's just me. I once had a unfired VZ24 7mm that my wife bought for me for Christmas. It was so pretty! But I had to shoot it. A few years later, I sold it for more than it cost. So firing it wasn't a big deal, to me anyway. It looked just as pretty as it did when it was in unfired condition. So I could see no loss, but I did get pleasure from shooting it!
I really can't see any harm in firing your rifle, but I wouldn't shoot the John Wayne ammo in it. I'd buy non-collector value ammo and use that. I really can't see any value in any unfired rifle, but then again, that's just me. If you are suffering anguish because your rifle is unfired, and you are not a collector, then it would be too painful to have such a fine rifle and not fire it. There's only 2 ways out of your predicament. Sell it unfired to a collector, if you are a shooter, or shoot it and have FUN doing so! Take pleasure in whatever you do.
