I would love to hit a range with someone who has a bunch of different calibers. My brother's best friend's dad is a plastic surgeon outside Chicago and has been on countless safaris and hunting trips. Has an entire wing of a large home as his trophy room. Impressive to say the least. One day he took his son and my brother to the range with everything he had. They shot everything from .243 to some .50 caliber double barrel elephant gun, with a lot in between. To say I was jealous when I heard about it is an understatement.
If I start developing an arsenal, I'd probably look to reload. But shooting as infrequently as I do, I don't see it happening now. To date I've shot two calibers...a single round from a .300 Win Mag back in 1995 when I scoped myself and then a .30/06 which I own now. I've always wanted a .280, but may look at getting a .270 instead as the difference in ammo prices is pretty noticeable. I bought a cheaper Remington 783, but may look to trade it in or sell it and put more cash to something of a little higher quality.
