I acquired this rifle about 20 years ago,it's a late model version E Series with the budget minded stock. I took off the old painted on finish and refinished it myself. She has only maybe a 100 rds. of factory ammo fired through it but I've been shooting lots of cast loads in it as of late.
Although I have a good supply of factory brass I started reforming 308 Win. and 7.62 NATO brass back into 300 Sav. a few years ago I like the NATO brass better as it's much thicker and will last a long time. An added bonus is that due to the lesser case capacity with the lower velocity cast loads I can gain around 100 fps. MV over an equal load in a factory or converted 308 case.

Case conversion is basically a three step process. Resize the expanded base of the NATO cases with a 06 FL resizing die,reform the shoulder with the factory 300 Sav. FL die and trim off the excess brass.
