greatmoose 4 Posted April 30, 2008 Report Share Posted April 30, 2008 I cut down my barrel on my 308 a bit, and I don't think my cut is very square. What's a good way to make sure it's square? I've got Dinzag's crowning tool, will that do it, or do I need to square the end up first? Thanks! Quote Link to post Share on other sites

greatmoose 4 Posted April 30, 2008 Author Report Share Posted April 30, 2008 Wow, that's not a small number! Quote Link to post Share on other sites
Leo.Kermes 1 Posted April 30, 2008 Report Share Posted April 30, 2008 Wow, that's not a small number! It is what I use, it faces the barrel to 0, cuts the 11 crown, and the 45 chamfer Quote Link to post Share on other sites
VanKiller 322 Posted April 30, 2008 Report Share Posted April 30, 2008 Gotta love the work created for gunsmiths by a man with a sawzall.............Brownell's has some home-owner grade crowning tools which can do pretty well for occasional use.....not really good for a production shop, but you might take a look to keep your costs down..........

Cobra 76 two 2,677 Posted April 30, 2008 Report Share Posted April 30, 2008 On my .308 barrel and also my friend's (KrisFox's) 12 gauge, I used a hacksaw and marked it first with a pipe cutter to get a good reference line. Checked it for square with a framing square and sanded / ground it smooth using a dremel with cutoff wheel and grinding stone face on. Then I used dinzag's crowning tool to finish it off (the rifle barrel). Turned out great. Installed the newly reamed out FSB on the .308 by eye and the first shot from 30 yds was dead on with the irons, freestanding off the shoulder. Quote Link to post Share on other sites

OK, I won't worry about it too much, then. Thanks! Quote Link to post Share on other sites
Azrial 1,091 Posted May 1, 2008 Report Share Posted May 1, 2008 In a pinch you can level it with a plumb bob in a vice. Then use a file to square it off. Re-crowning can be done with a brass bolt and lapping compound with a drill press. These are WECSOG methods, but they will work. Not as well as the methods outlined above, but then again you did not bother to shorten the barrel in a lathe either. Good Luck! Quote Link to post Share on other sites
