There seem to be many Ruger Blackhawk owner/operators using this (most excellent) site so I thought I would see if anyone has experienced something that I have noticed regarding my SBH.The front of my cylinder has developed small pits at the inner and outer edge of the "burn rings" that form during firing.The inner edge of the forcing cone also was worn and no longer held a sharp edge(the rifiling looks fine).I returned the revolver to Ruger with a letter stating my observations,and it was returned with a recut forcing cone.My other .44 Mags(including  SBHs)do not exhibit this on their cylinder faces.This SBH was my first .44 Magnum and has seen the most "action"-luckily I own more 44s now and the shooting is now spread out between them.Has anyone noticed this on their revolvers? The forcing cone wear I understand,but the cylinder? The gun still shoots great thankfully.

My SBH just turned 23 and what you got is strange.Never had the problem,run better'n 10k rounds thru mine without a flaw,did have the forcing cone recut though some years back.Strange indeed.No comments from Ruger on this?

Arizona Ranger, I had this happen to my SBH back in the mid 70's. I was useing a lot of WW 630 powder,(since discontinued). It turns out this was well known to cause gas cutting at the back of the barrel/forcing cone area. It was at it's hottest right at the cly. gap. the cyl gap was almost .010! I was envolved in handgun metallic silhouette and practiced a lot.

I sent Ruger a letter telling them what I had, they replied send it in we'll rebiuld it. It was originally equipped with a 7.5 inch bbl. The 10.5 inch was just being introduced, so I had them install the longer bbl.

They totally rebuilt the revolver. The only parts on the gun that were original were the frame and cylinder. New grip frame, barrel, hammer, trigger, springs and all new screws. the frame and cylinder were rebuffed and reblued. Total cost to me was &#3629.00 + shipping one way!

Ziggy,never ran 630,most was and is 2400..But an.010 gap yep that would make sense..Mine came from the factory at .006...Turned it back a hair to .003...Big Difference..
You got yours reworked abt the time I bought mine,cause my dealer had just gotten his first 10.5" in when I bought my 7.5"...You like the 10.5"??Jus curious,never ran into or talked to anyone with a 10.5"..

A R, I like the 10.5, the extra weight helps tame recoil a bit, besides if I can't hit what I'm shooting at with it, the barrels long enought to thump them on the gord with it. <!--emo&:D--><img src="http://beartoothbullets.com/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt=':D'><!--endemo-->

I first figured out what was happening when I kept tearing up my jeans when shooting the creedmore position at ihmsa.

I had just bought an 8 pounder of 630 when I discovered what it was doing. I kept it around till last year when talking to a guy at a gun show who was very glad to give me 15.00 a pound for it! Durn near doubled my money.
