Recrowning an SKS ? ?

[Chuckindenver]

i went out in my shop, grabbed a crusty 17 barrel out of the pile of crusty rustys i have pulled.
dropped it on the concrete driveway a few times for good measure, and dressed the crown with a RCBS case trimmer primer pocket tool.
though this is not the correct way to dress a crown, it will work in a pinch, lack of funds, or on just a cheap rifle is in order.
i didnt go very deap, and if i were actually going to use this barrel, i would have gone a little more, and likely dressed the crown itself with sandpaper ect..but you see what i was getting at.

I have the Brownell's "Facing Cutter" set. It works like a champ. I bought the set for what I thought was going to be a "One Off" job and cried when I wrote the check. But, since then I have used the set many times and it has easily paid for itself. Initial cost seems high but, after that you just need to buy pilots to do other calibers and it's not so bad.

the reamer used on my lathe, has the same conture as the RCBS case trimmer.
what differance does it make if it says...RCBS, or Spanner tool company. the end result is the same.
nobody is butchering anything...do i think the way he did the job is a little rough??yup, would i have done the same? nope..but..not everyone has deap pockets, and i understand not wanting to spend big bucks on a 200.00 rifle.
though i have the right tools for the job, i can also get the job done with basic ones as well.

The difference is your hand is not a lathe, your hand does not spin as fast as a lathe and your hand is not as rock steady as a lathe. Also a trained Gunsmiths who attended Gunsmithing school would NEVER use a RCBS deburring tool to recrown the muzzle of ANY firearm.

The difference is quality of workmanship..........

Chuck always gives great advise
Chuck realizes that not all have the money to do the perfect profesional job all the time and that people like to learn to DIY.
I love do it DIY jobs, one reason is I don't have deep pockets and I like do what I can myself.
No my Crowning job doesn't look the best, but for the tools I used I think it is pretty darn good and as you can see the end results "Target" shows it shoots straight.
No I wouldn't do this to my Custom Colt 1911, but this is an SKS battle rifle and it didn't get butchered.

Edward Horton:
This is not a Flame, but I personally get very put off by people that think their way is the only way and that if it is not done that way it shouldn't be done.
Your right a Gunsmithing school probably wouldn't teach useing a case trimmer for Crowning, but this is not a Smithing school, it is a Forum where members help each other.
I have received alot of good help and advise and hope it continues.
You are right, I am a (Cheap *******)

Interesting how life imitates art - or should that be the other way around? The rebated boattail and the thinking behind it match the the "Gunn-Davidson" bullet presented years ago on the Long Range Muzzleloaders Forum. With cast lead bullets the "corner" of the base is weak point for consistency of form and sharpness, and the rebated provides a cleaner gas-dynamic break when the bullet exits the muzzle. It is interesting to note that Edward's source (Ed, please tell us where it comes from) also says that flat-base bullets can perform better than boattails for accuracy. The purpose of a boattail is to reduce drag and thus flatten the trajectory. Somehow the illusion has been spread that this automatically improves accuracy. It ain't necessarily so. Thank you Edward!

common Ed...really??the OP was about repairing a crown WITHOUT A LATHE...do i have to chuck up a crap barrel in my lathe??? really???
keep with the spirit of the post...dont go over board if your not capable of keeping it simple, and having an open mind.
if someone attends a {gunsmith school} that does not make them a gunsmith...that paper on the wall doesnt matter squat,.if you dont have a basic understanding of KISS.
and by the way,,,the muzzle you have chucked up in your lathem isnt finished...it still need counter sinked....what tool would you use to do that????ONE THAT LOOKS JUST LIKE THE RCBS REAMER... how many of these guys do you think have a lathe???maybe 5%.... the OP was how to fix a muzzle WITHOUT A LATE OR FANCY TOOLS...

I believe the OP's group fired afer the recrown job indicates that no degradation of accuracy occurred, and if his sights are reasonably "centered up", then what harm was done? A collector grade weapon it wasn't.

Did he hurt the resale value? Not as a shooter. Probably not much as a collector's piece.

I think he showed initiative and some common sense, myself.

Y'all play nice, and try not to lose perspective!
