Clark Posted April 29, 2008 Report Share Posted April 29, 2008 I am sporterizing a rifle and giving it to the girl of an Iraq vet I have never met. I have been working every night for 8 days: The list of what I have done is: True face of receiver Center the barrel in the lathe Change lathe gears for 12TPI Grind 55 degree thread cutting tool Cut barrel threads, shoulder, clearance, tenon, and chamfer chamber orifice Grind trigger hump Mill off charging hump Chamfer charging hump File charging hump sandpaper charging hump Drill and Tap for scope mounts Shorten mount screws Mill mount for height and offset Cut off bolt handle Weld extension on bolt handle Put extended bolt handle in lathe and smooth out weld in the center Weld extended bolt handle to body Mill welded bolt handle File and sand sharp edges on bolt handle Blue barrel Blue Receiver Yet to be done: Get ammo to feed. Cut down trigger guard width Blue trigger guard Mill safety shroud Blue Shroud Assemble M70 safety Broach barrel channel in stock Pillar bed stock Glass bed stock Sling Load ammo Break in barrel Mount target scope & test accuracy Mount hunting scope and sight in Ship I got stuck last night on the feeding. In the past, I have got 300 Win mag to feed perfectly, even up side down in am VZ24. To do that I made the mag longer in the rear and opened the lips. So on the 243, I can cut the lips, weld the lips, block off some magazine in the rear, block some in the front, or a combination. What did you do?

gun nutty Posted April 29, 2008 Report Share Posted April 29, 2008 Why the .243 Win? In a Mauser, the 6mm/.244 might be a better choice for feeding. Link to comment Share on other sites More sharing options...

This is for a girl on the East coast that will use factory ammo, and I have a 243 reamer. Link to comment Share on other sites More sharing options...
z1r Posted April 29, 2008 Report Share Posted April 29, 2008 I'd try a block at the rear, then widen the rails at the front to accomodate the wider shoulder of the .243. Or, you can borrow a page from the Chileans who, when they converted to 7.62x51, blocked at the front and cheated by incorporating a feed ramp extension into the block.

carzngunz Posted April 30, 2008 Report Share Posted April 30, 2008 The only 243 that I have done was modified just as Z1R suggested. After opening the rails a little it fed fairly well. I found that my extractor was too tight against the cartridge and was causing some problems. After reducing the extractor tension it fed like it was made for it.
