elenius Posted December 28, 2006 Share Posted December 28, 2006 I got sick of cartridge heads catching on the chamber edges, so I got a 1/2" counter sink from Home Depot, and I'm about to do some damage to my Ruger GP-100 However, I would feel much better about it if I had actually seen chamfered cylinders before How much should I chamfer? Anyone with a 38/357 out there who can tell me what the max diameter of the chamfered hole should be? What do I do about the extractor star? Should I just chamfer with that in? Will it still push out the cartridges ok, or will they slip off the star because of less contact surface? Link to comment Share on other sites More sharing options...
Viggen Posted December 28, 2006 Share Posted December 28, 2006 The first time I did it I just took the sharp edge off with a countersink sold at one of the warehouse places then buffed it a bit to make sure it was smooth - just hand turned the tool about 5 or 6 tiimes with little or no pressure just to see if I would break anything. To my surprise, just taking that sharp edge off a bit really, really helped. Forget about max diameter, don't go wild for now, and just take the sharp edge off - and shoot RN bullets.
