If you already have bolt guns in 223, the trail wont be scratching any itches for you imo.
7.62x39 bolt guns are awesome and everyone should have one, moreso in your situation if youve already got the ammo. My 7.62 trail LOVED steel surplus ammo. Shot about 1.5 moa at 100yds, never missed the man sized gong at 400. Awesome little gun. The 2 mags it comes with were very good quality, gave me the impression theyd last the life of the rifle for sure. Ive never needed more than 2 mags for a bolt gun myself, most i only have 1 tbh. Semis im the type of guy to have 10 mags per rifle but bolt guns i just am never shooting fast enough to want more than 1 or 2 but thats just me, so wasnt an issue. All that said i sold it and replaced it with a Ruger American in 7.62x39 which is an awesome gun, but i still miss the trail and how compact it was with the stock collapsed.
