I have barrels in 223, 22 hornet, 22-250, 7mm-08, 7mm mag, 308, 30-06, 32-40 and 12 gauge slug. Have two frames, but both are single trigger hunter types. You stole that rig for $500, be happy! As for recoil, while the gun is light, the stock is well designed and even with 12 gauge 3 inch mag slugs, doesn't kick too bad. Makes a good hunting rig for places where there are lines between rifle and shotgun counties. My 12 gauge slug barrel is smooth bored, but shoots about as good as my hastings rifled barrel on my 870, 100 yard groups with winchester bri slugs run about 3-4 inches, i have a 1x burris scope on that barrel. the 7mm-08 barrel is as accurate a firearm as I have ever owned it is a 26 inch medium sporter weight. If you want a challenge, try finding a 32-40 barrel and make it shoot lead bullets with black powder well....I haven't been able to make that work yet...does well with smokeless lead and jacketed, but no real joy with BP.
My only complaint about the TCR is that Twice, I've had to send one of my frames back to replace the firing pin and firing pin spirng. TC fixed it free both times, but I don't think they did it right the first time, been great since the second fix.
