Looking for options, have a model 300 savage model 99 that will misfire from time to time. Gun smith I talked to stated that the tolerance on these guns were not to tight and over time the bore wore and the cartridge pushs down into the barrel causing the primer to be to far from the firing pin. Any ideas what it would cost to have a new barrel made or could I have it re-bored to a 308 because the cartridges are longer and would not have to machine as much out of barrel and the dia would be the same any thoughts out there about this?

Can you post pictures of a fired cartridge case head? Looking for a primer image.
In most guns, a cartridge of the incorrect size (loose in chamber) can fire because the extractor will hold cartridge case to bolt head.
I have a .30-30Win that has excessive headspace and will fire, and I have not had a miss-fire yet, but the brass case is deformed from this excessive headspace and easy to measure the deformity.
Have you inspected the firing pin? How much does it protrude from bolt face when pushed forward?
I don't know if the 99 is an Inertia firing system or not, but one can still push pin forward where hammer down on pin won't unless it flies forward on trigger pull.
I would also Clean bolt thoroughly.
I would be suspicious of someone giving a judgment like you got without a chamber cast.
