In 2012 my house was involved in a forest fire and consequently my guns where damaged even though they were in a fireproof safe. When I opened the safe all the wood was nothing but ash. I cleaned, refinished and put new springs in my Springfield 1911 and Beretta 92F. They shoot just fine in fact the 1911 shoots better than the brand new Remington 1911. Now I am looking at rebuilding 2 marlins. I have a 1895CB in 45-70 and a 336 in 30-30. They have been kept inside since the fire and do have small rust spots which seem to cleaned up easily with a little work. I am thinking of having the 336 barrel re-bored to 38-55 or re-finishing the 1895 leaving it in 45-70.
My questions are:
Are these rifles able to be rebuilt?
Should I keep them in the same calibers?
Kinda off subject, can you shoot 45-60 ammo in a gun chambered for 45-70?
