Acceptable DIY way to shorten my rifle barrel?

I have a Savage 10FP in 308 w/ a 24" tube that has a blemish just about a 1/2" before the muzzle. It looks like the button got pulled out cockeyed or something & scalloped a deep spot in the lands & grooves. I'm having some accuracy issues with this barrel so I thought I'd just cut that last inch off, recrown it & see if it fixes it up.

A friend of mine has an 11° crowning tool with a 30 cal pilot that he's let me borrow. He used it when he chopped his Nagant barrel, hacksaw + crowning tool in a hand drill = good enough.

Ultimately barrels are consumable so while I don't want to spend a lot of cash to do this, I don't want to screw it up either.
-For cutting I have a hack saw as well as a chop box. Would either be acceptable? I know the chop box would put a lot of heat into the cut surface so I didn't want to risk warping anything..?
-For crowning I could use a hand drill or figure something out with my drill press, not sure what though as it's not tall enough.
-For finishing the lands to crown edge I've heard you can just put a brass finishing screw in a drill & run it on the surface.

Thoughts or ideas? I tried searching but didn't come up with much. Thanks!

Thanks guys, that's what I was thinking. I'm not tied to a barrel length so if it comes out poor I know a guy I can call.

Because I'm a problem-solving, DIY kind of guy! The main reason I bought this Savage was because I wanted to do my own tinkering / smithing, and I don't own a lathe...

Jenrick, I read that article a couple years ago & it gave me some confidence in DIY. Anyway, I did the deed today. I think it came out pretty well. First I decided that I wanted to take off 1" to clear the blemish. I measured & marked. I then took a pipe cutter to scribe a perfect circumference, and it did, but be forwarned it destroyed the blade on the cutter in the process.

Next I made the cut with a hacksaw using a new metal blade. Oops, skipped it a couple times in the beginning! In hindsight, considering how deep the 11° crowning tool cuts it in I would have no problem (heat concerns) using my chop box. Heck, it probably would have come out straighter- even with the scribe the hack saw blade walked a couple MM at the bottom.

JM, Lighting the bore I could see both ends, and the only blemish was at the muzzle. If I did screw it up I'd just buy a new barrel & screw it on. Plus, I'd really rather not ship my rifle all about the country if I don't have to. Plus plus, they'd probably tell me it was within spec & not fix it.

Hacking done, left with a rough surface. Not quite square but that'll be fixed. I thought the sawing may have tore up the lands at the end, but actually they looked fine when I cleaned it up.

Started cutting the crown with the PTG 11° crowning tool w/ the 30 cal pilot. Used a hand tap-handle. Progress is slow.

Thinking that I might pass out a month or so before I could cut as far as I needed to with the T handle, I enlisted the help of my air tools. The tap end was conveniently 3/8", & I used my universal brake piston tool as a F-F coupler to hook my 3/8" impact up to the cutting tool. I used plenty of ATF as cutting fluid & cut away.



Some time later we have a nice crown! I finished the outside edge with a brass whiz-wheel hooked up to my air drill, worked great. I forgot to take a pic of it but I finished the lands by taking a brass finishing screw, chucking it up in my air drill, and using more cutting fluid running it both directions at the end of the bore. The screw was the perfect size for the job. The end result is that the edges all look great.

Once all the cutting was done I used carb cleaner to clean & degrease everything well. I ran a jag & a patch up to the end of the bore to push out any shavings, and to keep the carb cleaner from running down the inside of the barrel. Once clean I dried everything to finish the prep for bluing. I used some liquid blue I picked up for 4 bucks. This photo is after the first application- I've been applying / drying / prepping / applying & I'm up to the 4th coat now, trying to get it dark to match the original finish.

Oops! Well, for $148 I'll just stick to my chop box.

So here's the end result, looks good to me. I loaded some rounds today & went to the range- 35 degrees, Brr! It's definitely grouping more consistent since removing the blemish. No unexplained flyers like before. I also tried a load that gave me inexplicable / horrible results previously & it shot acceptably today- big improvement.
