From a 300 Savage. Functions great. Blue has issues as seen in pics. No cracks in wood, that I can see. Aftermarket butt pad, has rear sight filler and comes with bases. For those interest, 11J date code means a 1958 model. $599 shipped.
Best way into a great Savage lightweight rifle in this cartridge. You'd pay twice that for an identical factory 358. I hunt one I put together using Savage parts and it's a great rifle. Otherwise...
However, the original .300 Sav magazine rotor may have had to have some metal work done to load and feed .358 cartridges.
Not common to find a 99F donor for ~$360.00.
Add the 225.00 that JES charges for a 3 groove rebore including magazine modification and your shipping+Insurance cost to JES, it will be close to the seller's asking price.
