Check and see if that Cooey is really FULL choke. They were swaged when choked instead of bored and reamed. My 84 marked FULL is actually a loose MODIFIED. I shoot steel in mine with no apparent damage and fairly good results. The old dime will do as well any when determining choke. If a dime passes it is safe with steel 2's and smaller.
cheers Darryl
so you are saying that if a dime can slide from the action down the barrel its ok? the other cooey i have easily could fit a nickel down the whole barrel. its marked full choke too....?
No it can't handle steel shot and yes, you could open the choke to accommodate the hard stuff. It would cost half as much as the gun is worth to do that. Or, you could purchase Kent tungsten - matrix shells and shoot the gun as it is. The Kents cost more than steel loads, but the only time you need them is when you are actually hunting waterfowl. The TM loads have superior performance compared to steel shot IMHO. The rest of the time you could just use lead shot (at the range, for upland birds, etc.).

little more to it than that billc68. the bore diameter has to be measured first with an inside micrometer. standard 12 ga. is .729" either way. industry standard allows for .005". if the bore diam. is .730 and the muzzel .700 you have a rate of constriction .030 or improved modified. carbide reamers work from the chamber out. brownells reamer works from the muzzle in on a large tap handle. a dremel tool will be kinda hard to keep the dimensions uniform!!! the last thousndth of an inch is taken out with a rotary honing stone. if you have a chrome barrel then the carbide reamer is a must. all cutting is done with cutting oil and the muzzle should be measured after every cut. the digital calipers are used to measure the expandable reamer to see how much is being cut with each pass. you need both measurements BORE and MUZZLE to acuratley find out the rate of constriction or choke. then you go from there.but calipers and a dremel tool alone will not do it,except to screw up your barrel. as far as patterning is concerned. each shotgun patterns individually,regardless of the shot size.a lot aren't, but when reaming out choke, the gun should be shot with each pass , 1/500 or even 1/1000 of an each to find the sweet spot.

okay if the customers happy and paid him ,everbodies happy. i guess . i didn't think i was being pichy. have a good one!!
You were not being pichy, you were simply stating what has to be done to get the job done right. Some who do not know what they need take it to those dremmel butchers who are not smart enough to know they are out of their league, and between the two they do not know what a s**tty job has been done.
remember how I put "smith" in quotations....
But when you are dealing with a $200 or less gun, if it work it works... right?
Lobbing a couple inches off and making the bore a true cylinder is the only job the "butcher" should be allowed to do.
If a fellow had to shorten a shotgun or rifle barrel, what is your opinion on using a bevel protractor to get the angle right with some careful filework, then ending up crowning the barrel like Clyde Baker advised? In your opinion, would that work okay? Regards FT. Sorry didn't really mean to hijack just had to ask.
