Boring .32 Colt NP to .327 Fed Mag

[Spots]

So i recently put a gem of a Detective Special on layaway, chambered in .32 Colt NP aka .32 S&W long. I would like to have it reamed to accept .32 H&R Magnum or preferably .327 Fed Mag. Are there any gunsmiths local to Knoxville who would be up to the challenge? Ive seen Det Specials reamed to .32 H&R mag, but I cant find one in .327 fed. Not sure if its a pressure issue, OAL issue or just nobody has done it and put it on the internet. Any help on a shop to discuss it worh sould be appreciated

Unfortunately, that Detective was never intended to handle factory loads that run 45,000 psi chamber pressures. Thats like double what the 32 H&R has in a factory load. It would be a nice upgrade in 32 H&R and safe to shoot all day long without worry of putting the cylinder out of time and rattling the cylinder pin. Those parts are rinky dink duty to hold 45K in check. The net says they developed the round in a Ruger SP101. That like half ton PU to a Kenworth in construction strength.....not even close. Consider the 327 is dam near 357 mag pressures. Step back to the H&R and its a tad better than the OEM but then do you really want to bubba such a fine condition old Colt? If it was a tackle box rat, thats one thing, but that sure doesent look like one to me. The good thing is, it would still shoot whats stamped on the barrel just as well with the lengthend chamber so it could be your secret if you want it to be. Any Gunsmith could do the job, They would only need to rent a 32 H&R cylinder piloted reamer from 4D rentals , cut n polish and done. Good Luck with it.
