Ruger Blackhawk fix?

yeah, but where's the fun in that?

in all seriousness, i don't know. but, w/ your proximity to ruger, can't you just whack one of the floor workers over the head w/ it, and tell him to get it right, and as long as he's at it, tighten the cylinder-to-barrel gap, too?

NH--What is this gun doing or not doing that it needs fixed?

    A lot depends on, cast or jacketed bullets, ( bullet dia.) factory or handloads.

2 1/2 FOOT groups.  I don't know the range, but most revolvers with the barrel screwed out (aka belly gun) will shoot 2 1/2 foot groups.

I would not do anything with that gun but send it back.  This is not meant to be critical NH, but does it shoot that bad for other shooters?  Is that the tightest group your dad can shoot with the same ammo?  Ruger has always stood behind their products and if something is that wrong, they would surely rebarrel it and check all fit.

If it's commercial ammo and you don't reload for it yet, I would first try differnt brands and differnt weights. Also take the cylinder out and mike the throats on the chamber, and check it against SAMMI specs. If that doesn't do any good , get a set of dies and work up some loads for it, both jacket and gas check lead. For the lead bullets, try to get some sized to match your throats.

Are you sure your not talking about getting the forcing cone modified? 

Miked is a slang term to use micrometers to measure something. I your case, you would have to use inside micrometers to measure an inside diameter. Regular dail calipers don't work as well because they are not as accurate as most micrometers. You are probably looking to see if something is within .002-.003  inches. There are tools  that you insert in a dia , they lock up, and then you remove thme and measure with an outside micrometer.

Having the " throast reamed'rfeers to aprocess wher you openup the dia of the throats in your cylinder chambers. The front of the cylinder is a few thousanths smaller than the back to accomodate the differnce between the cartridge case dia, and the bullet dia.

The most common caliber this is done with is the 45 , because there have been so many variations of the old colts through the new ones and the clones, and a lot of manufacturers cut thiers different. Even a lot of 44's are sized both .429 and .430, depending on what it being used in.

So if you can get your throats measured, you can buy the appropriate bullet for it or if you cast your own, you can buy the appropriate sizer .

In light of all this, you would be wasting  money having the throats reamed , when all you have to do is purchase or cast the right sized bullet. It might very well be  that some work needs to be done on the cylinder, but it's best to check out  what they are before just having it done. First thing to look for is if they are all the same size or vary a lot from cylinder to cylinder.

Well it looks like leading. I dont cast bullets, but maybe the last person who had it did. I bought it used for just over 200. I shot some of those winchester lrn bullets but i dont think they did it, because i think i remember seeing the stuff in there before i shot it.

Try this:

1.  Check the gun for overall mechanical condition -- proper timing, lockup, end-shake (fore-and-aft movement of the cylinder.)  BE sure to check these things for EACH chamber.

2.  Clean the gun thoroughly -- an Outer's Foul Out would be a good thing to use here.  Get all the copper and lead fouling out.  Get it squeeky clean.

3.  Check the forcing cone (the "funnel" at the back of the barrel, where the bullet enters.)  If it is cracked, you need a new barrel.  If it is corroded, pitted, rough, or eroded, it may be possible to recut it -- Brownell's sells a tool to do this.

4.  Slug the bore.  With the chamber removed, mount the revolver in a padded vise and gently drive a slightly oversize PURE LEAD ball through the bore.  Measure it with a micrometer.  You want to use bullets that are bore size (for jacketed bullets) to about .002 oversize (for cast bullets.)

5.  Slug the chambers.  With the cylinder mounted in the padded vise, drive a lead ball through each chamber (mark them so you'll know which ball came from which chamber.)  Chamber throats should all be the same size and .001 to .002 over bore size.
