Method relieving stock barrel channel for larger diameter barrel Questions

[p5200]

I'm going to install a Lilja 1.00" barrel in a CZ 457 Standard Varmint stock. My question is, do I start at the bottom of the channel with smaller socket/ sandpaper? Or, start at top of channel with final width of socket and sand paper needed. I just want to avoid the top finished edges from getting chipped or scuffed. I suppose I could tape off that top edges? I'm open to all suggestions / ideas! Thanks!

Top of channel with final dia. Socket. And yes, tape off the top edges.


Also, you may already have noticed that you inadvertently posted this thread twice. Just go back into the second one and delete it.

I thought I'd deleted it I'll try again. Thanks

The socket /sandpaper combination measures .060" over which should leave .030" clearance on each side. Does that sound about right? more /or less maybe?

That should be fine.

either way will work. If you go small socket and follow with larger be careful you don’t cut a Chanel in the forend that’s out of round. If you go large all the way watch your top line to make sure you’re cutting evenly all the way down the barrel channel and not opening some spots up wider than others.

You can run yourself ragged with one of these Jerry Fisher scrapers as well. Nice even passes until it fits

When I did this process on my Manners stock, I used a piece of aluminum tubing instead of a socket. It worked very well to keep things nice and even. I wrapped the sand paper around and pinched it at the top while I was working. That way it didn’t have any chance to take material from the upper edges.

I would suspect for a 1” barrel this would work great.

When I use a socket and sandpaper, I connect a fairly long extension to the socket.
It allows you too use two hands, and gives much better control of the outcome.

I got the job done. It appears pretty even on the margin space all around the barrel. With the new Lilja, ammo feeds, fires, and ejects just fine. So, I guess it's headspaced properly. With the Receiver and shank measurements, I shimmed for .042" headspace. I wound up using a deep well socket and sand paper. Thanks for the help folks!

Brownell make a tool to opening up a barrel channel. I had one to open a 10-22 stock for a bull barrel. worked great.
