Crown

Leave it sharp, or break the edge

 

Sharp and use a sharp cutter.

 

you guys are waaaaay above me I'm really just seeing if my membership has been upgraded.

 

and it has! Knew it was about this time last year. Gary

 

I leave it sharp, just wondering what other folks do with it

 

Sharp on a target rifle. Youll have a drawer full of tools before you find the right one. When you do itll resemble this one

 

I use a sharp high rake hss bit and add a small 45 degree chamfer on all crowns. As long as it’s clean and concentric is the most critical IMO.

 

Sharp and slow works for me, nothing more...

 

Micro 100 solid carbide mini boring bar for breaking the edge. Razor sharp and does a great job. Many of the top smiths use this bar with great results. Carry on.

It doesn't matter. I've done thousands with a chamfer. All indicated in +/- .00025"
The universal test. Run a Q-tip in and out. Does it pick up any fibers?

 

Yup, that's the tool.

 

So what's the purpose of dumping these here?

 

Positive rake inserts for AL leave a baby smooth crown for me. I’ve done flat & 11 degree, can’t tell any difference. I’ve broke the edge and left it sharp. I’m probably not a good enough shooter to know the difference. Just test it yourself and prove to yourself what is best.

 

I am with Dave Tooley on this one I always use a small chamfer and it helps to keep from scraping the coating on your cleaning rods. Sharp crown works ok but It gets damaged faster I think.
