I can't imagine having guns that I've never shot.
Most of my rifles and shotguns get shot less than my Remington 700 and Benelli M1S90, but I have shot them a good amount of times. A lot of it has to do with not having Mosin Nagant ammo, and just un-availability altogether.
The .22WMRs get used to shoot chucks. The Marlin M60 is my range .22, which is actually used relatively frequently.
Mosin Nagant is fired when I have ammo.
I shoot my T/C muzzle loader before hunting season. It's probably the most accurate rifle I own, with the best trigger, but the amount of effort it takes to clean it, it's not that much fun to make a range day out of it.
My other muzzle loader (side lock, traditional style) doesn't get shot because it was a kit from Spain. The steel is terrible.
The 870 gets dragged to the range time to time. I'm planning on using this for trap league this spring.
The 20 GA. 1100 has been shot a couple times, and it shoots dead nuts (sub MOA/MOA @ 100 yards). Probably handiest gun I have right now, but I've had it for almost a year. Plus it's hard to find the Hornady SST Sabot Slugs. But let me tell you, those SST Sabots are great.
The Benelli M1S90 gets shot during trap league.
THe Remington M700 (.30-06) gets shot most frequently at the rifle range. I just started to hand load for it and I want to be very good with it for next hunting season.
I feel like I forgot some
