Hi Ive just joined. I was a gunsmith from 1992 to 1997 and have 'dabbled' since. I recently acquired an unmarked No4 (Savage 1942) from a friend who bought it 32 years ago. He bought it and 250 MkVII rounds (also 1942) to defend himself from crocs in Northern Queensland when he and his wife made landfall in their yacht and needed fresh water. He gave it to me for a carton of beer. It was good beer I made sure of that but thats still a bargain. It has a bore that is unworn but rough. He only ever fired 3 shots out of it 32 odd years ago but didnt know to pour boiling water down the bore after. It scared him so he never shot it again, just oiled it well and wrapped it up. No deep corrosion just a micro pitted surface, like a parkerised finish. It seems to shoot well. I shot a couple of 5 shot 1.75" at 100yds with the fine peep sights yesterday but it picks up a lot of bore fouling. Would hand lapping with a bore-cast lap help? I have bismuth based chamber casting alloy and fine lapping compound.
