Hey ya'll , just bought a ruger superblackhawk stainless,5.5 inch barrel.(gun was made last year) does anybody know how uniform the throats are in these guns? I also have a 45 colt blackhawk and those throats were .002 undersize.. I fixed that with a $40 decimal chucking reamer. Im hoping i dont have the same problem with my sbhawk. Havent got the gun home yet to slug the barrel and throats cause of the 3 day waiting period.
As you have seen, in the past Ruger .45s tended to have tight chamber throats. My older ones certainly did. More recently Ruger is alleged to have gotten it right. Yours may be new enough to be good. Is it a Flat Top? That is the only stainless, 5 ½” .45 Ruger seems to be making at the moment.
