RE: All in one guns?
Jack of all trades master of none.
The encore is the only gun i would consider, but pretty expensive. Not really backup priced.
Most people I know that like encores are buying new complete guns, not interchangeing barrels.
This is only my opinion so no grief please, be careful of NEF and Rossi single shots in high pressure chamberings. As a shotgun, rimfire, muzzle loaders,or lower pressure such as 45-70 factory loads I am ok, but the 243 scares me to death. I have seen a NEF that has fired without the gun being completely closed, that was only a hornet and it recessed the reciever face when fired ruining the gun. Had it been a 243 I figure there would have been injuries. I have tried with other HRs and believe I could have fired the gun unlocked in them also.
Interchange guns are OK but not for me.
