Wow. I just bought a new SBH Bisley 44 mag, this thing is so accurate, it's scary, my fav load is Lee 240 gr. SWC pushed by 20 grs. 4227.
 
Hi ho hi ho it's off to Ruger it goes....:) You may drive yourself crazy trying to figure it out. Ruger made that revolver they know how to fix it, warranty or not that would be my advice.
 
To Ruger it does not have to go, hi ho hi ho.

The gunsmith called me and said he has cured the revolver. He was able to fire one inch groups at 25 yards off a sandbag. He said the crown was awful, but now it is good to go. hi ho hi ho:neener:
 
I skiimmed the thread, sorry. Is this a new purchase? My very fisrt pistol, 25 years ago, was a brand new Ruger 44 mag DA. You describe the exact reason I got rid of it. If your's is new, it sounds like Ruger has an age old problem. Or, we got the only two damaged crowns offf the line...
 
And to answer your question: yes - even a slight problem with the crown can cause accuracy to shotgun on you. the crown is the last thing the bullet can make contact with: and hopefully it doesn't.

Lets say the gun drops out of holster or pack and lands muzzle first in rocky soil. Pick it up, dust it off - it doesn't look like anything more than some scratches. What you may not see are small scratches which have burs or swagged metal in the riffling perhaps on one of the lands or in one of the grooves.

Just a little ding: now every time a bullet hits that itty bitty bump where its swagged: what happens is the bullets rotation is altered and it's no longer stabilized in flight. Anyone who's ever fired the wrong weight bullet for their gun's rifling can tell you: if the bullet doesn't stabilize you'll notice.

In this case though it's even worse because a jump or bump at the muzzle end will dig into the lead round and leave it flying with possibly NO spin at all. The rotation could actually come to a complete stop at the muzzle and continue flying through the air as such. It probably wasn't that bad: but yes - burs at the crown are bad news. they can alter the bullet's spin and if the bullet doesn't stabilize then it's going to shotgun from one round to the next.

I'd go have a chit chat with the previous owner: he or she probably sold the gun because it was scattergun accurate. Also, if he or she sold the gun because of that: then he or she should have told you that a head of time. Apparently: the previous owner did -not-. I would be really rather upset, personally. I would be less than happy. I'm very sorry you had to deal with someone attempting to take advantage of you like that: it's terribly unfortunate that some people are so unscrupulous.

That kind of thing really irks my chain.
 
Post results after the recrown.
SOMETHING is certainly not right, my Super Blackhawk will pretty much have all the rounds touching at 25 yards.

I'd try a few things,
1) check the sights, be SURE they are not moving or loose.
2) let someone else shoot it
3) be sure when if/when you shoot off a rest you aren't laying the barrel over something hard like wood. That can cause some very erratic issues.
 
Update

I picked up the gun the other day. It was ready last week but I decided to have the gunsmith smooth up the trigger.

Yesterday I got a chance to shoot the revolver and all I can say is WOW !!!

I set up a target like before, 25 yards using a sandbag rest. Great shooter now, it is a totally different beast now. It is shooting the way I had expected in the begining.
 
Cool.... glad it's doing what you want.

A Ruger single action is my go-to gun for the woods and mountains. My favorite is my New Vaquero in 45LC. A good-running Ruger is a thing of great pleasure!

I recently bought a Ruger Bearcat, just for fun. I couldn't shoot it well offhand and after benching it, found out why. It shot around the clock, but none in the center. Another cylinder full duplicated the "pattern" exactly, as did a third! Small 3-shot groups in six different places on the target.

It was a used gun and the Kittery Trading Post took it back without any questions. I checked the crown and that was okay and reamed the forcing cone a bit, which helped a bit, but something was amiss and timing didn't seem to be the problem. I suspect the cylinder boring may have been the problem.
 
It's not common to find a Blackhawk that won't shoot, but it does happen.

I've owned nearly a dozen Super Blackhawks over the years. They all shot acceptably well with two exceptions. One was a tack-driver. The other one wouldn't keep two shots within 6 inches of each other at 50 yards.

Give Ruger a call.
 
The crown problem need not even make contact with the bullet to throw accuracy off. The hot gases need to spread evenly behind the bullet as it exits the muzzle to keep from upsetting it, so the crown needs to be even all the way around.
