If the barrel will fit in one of your drills, set up a poor mans lathe (PML) and use the hacksaw as it spins. If not I would use the metal chop saw and go slow to make the cleanest cut. Make sure the cut is 90deg to the bore. You will want to clean up the cut, again in the PML if possible, using files and progressive grades of wet or dry. The brass screw method of crowning works well for me, but I chuck the barrel in the lathe and slowly move the drill around as they both spin..
Post a pic or too of the crown when you're done.

I have used a hack saw in the past. Will not heat up the barrel like the chop saw will, but will also not be as square as if you used the chop saw. Use a file and square the end off after cutting and then use a button head screw in you drill with some 240 grit emery cloth to finish the crown on the bore. It'll work!!

Midway has a YouTube video on how to cut and crown a barrel. They used a piece of angle iron cradling the barrel to use as a guide when filing to get the cut square. Try and find that video.

Think you mean this one?

Normally I cut them a touch long with the hack saw and finish in the lathe. If that's not an option, would do as follows;

Use the pipe cutter to make a gentle score around the  circumference of the barrel where you want to end up. Cut with the hack saw leaving some to clean up with a file.

File to the line, clean things up like Larry does (sand paper on the file) and crown using the method shown by Larry.

thats what im talking about right there.that dovetail jig is no longer available but im sure ther is an alternative.that jig is hardened thats what makes it easy to file without losing the squared edge

i have read that a button head screw can ruin your crown.is that why brass is suggested because it should be softer than the barrel steel.
i have a couple of barrels i practice on.im never happy with the crown.thinking it would cost effective to just get a crown cutter.when you are paying $30 a cut and crowned barrel after 3-5 barrels that extra money saved diy would pay for the tool.
i would thing one of those bench sander things with the disk and guise would make a nice square barrel.thats more important than the crown.your barrel will still shoot straight without a crown.the crown keeps it that way

it doesnt take much to do a crown.i guess i have been doing to much im going to try it like the video shows
it would be nice to see before or after targets

Here is how I did mine:
I made a set of blocks to hold the barrel and then clamped the barrel in between the blocks to cut it with a hacksaw.  See pics.  Then chucked the barrel in my drill press and lowered the cut edge onto a piece of sandpaper as it was spinning to true it up.  Forgot to take pics of that part.  Also in the drill press, I de-burred the outer edge with a file and 45'd the crown with a sharpened dowel with sandpaper wrapped around it.  Then I polished the crown with just the dowel and valve lapping compound still with the barrel spinning in the drill press.  It shoots better than any factory barrel I have.
As always, your mileage may vary.

it hasnt been available for a long time.its hardened so filing wont hurt it anything else will lose the squaring if filed on and not hardened
