I have an interest in different action types with different locking systems. I have side lever hammer guns, three different types of under lever latching systems in hammer guns. Most have thin barrels but none extremely thin or that expensive. Being a reloaded I can Taylor sane loads to keep pressure within limits I am comfortable shooting. Bursting is not my main concern but denying is a real risk so extra care must be taken. I shoot thin barrels but only if the thin area is well away from my little fingers. Have not dented any barrels yet but do know hunting with them that becomes a real risk.
I have considered buying several thin barreled project guns at auction but in each case a detailed inspection report has also found other problems which with the cost of sleeving and then importing made them prohibited from a cost viewpoint.
