Super Blackhawk problem

Well I obtained a new stainless 4 5/8" Super Blackhawk to shoot cast bullets and the darn thing shoots 6" high at 25 yards with the rear sight adjusted all the way down. BTW, this is using 240 gr XTPs and 296 (I had to try it before moving on to lead). I slugged the cylinder and the bore. The cylinder measured .430 and the bore measured .427. Apparently the .427 bore is the problem, but what are the solution options? Hand lap, fire lap, or send it back?

Thanks.

The bore size is not the problem as long as they cylinder is over the bore size you are ok.
You could try lighter bullets (heavier bullets will impact higher due to recoil) or like was said get a taller front sight I would get the tallest one I could find if your already bottomed out then you could file it down also if need be.
 
Short barrel Ruger revolvers are notorious for this; they install a too-short front sight at the factory, and this is the result. It will be even worse with heavier bullets. You can return it to Ruger and ask for a taller front sight, or you can order a taller front sight blade and install it yourself - the blades are pinned in place on the stainless guns. Those are your options.

Personally, I would call Ruger and explain the problem, and politely request a replacement sight blade. They'll probably send it at no cost.

And personally, I think you should slug the bore again. It's certainly possible that there is a constriction under the frame threads, but you need to verify that. Drive one slug all the way through the bore and mike it. Slug the bore again, but stop short of the frame threads, then push the slug back out the muzzle and mike it. Compare the two measurements. Fire lapping is one solution to that particular problem.
 
I have a 5.5" Stainless 44 Magnum, and have the same problem your having. I might have to call up Ruger once I get a little more range time and verify it from a good rest.
 
Your issue is probably the front sight blade, you need the one used on the 4 5/8 45 Colt Blackhawk. If your gun is stainless it is an easy fix, if blued the fix is not so easy.
 
Call Ruger and they will send you a lower rear sight blade. They sent me one for my super blackhawk hunter for free, and it took care of the issue. They are a bit aggravating to install, but you can't gripe about the price. My question is, if they have them, why not intall the lower rear at the factory, or include it in the box with instructions for changing it.
 
I actually called them. The lady I spoke to struggeled to figure out what caliber my Super Blackhawk is. Finally she declared there is no other front sight blade for my pistol and decided I need to send the gun back to them. If I do I figure they will un-do my trigger job.

You are correct they just may return it to factory and send back any aftermarket parts.

Call them back and just tell them you need a front sight for a 45 Colt Blackhawk don't make them think
 
Not sure if this will address your problem, out of 3 .44mag Ruger revolvers I had two of the barrels rotate (turn). The first was a SBH and I sent it back (my expense) they reurned it repaired 30 days later which was ok. The second was a Redhawk also a 7.5" with a scope on it and could not sight it in after some shooting. This time C/S had some concern and sent me a pre-paid shipping including ins none of which is cheap. They replaced parts and to date it works ok but I have not fired that much thru it. My SBH barrel turned again and I asked Ruger to be kind as I had the barrel cut down to 4.5 to shoot only .44sp so voided the warrenty. They repaced everything on the gun except the frame and the cylinder and installed a 4.5" barrel. I am happy with this. Not to be alarmed about Ruger, S&W had the same problem on .44 mags and pinned there barrels. It is easy to tell just look at it from the muzzel and see if its square.

Heck, I didn't mention this is not the first one I had. The underside of the barrel on first one I bought split using factory loads. I took it to the store where I bought it and they sent it in. Ruger re-barreled it and sent it back. They may have done other work I don't remember (this was about 5 years ago) or am not aware of. That gun never shot worth a flip and felt quite loose. I traded it back to the shop where I bought it. Recently I decided to give it another try and what do ya know? I got another dud.
 
It's probably not a dud. I have had very good luck with Hornady 180's. That will bring your poi down some. Unless you hunt bear, not much will stand up to a 180 HP at 44 mag velocity.

Thought about that, but I bought it to shoot cast bullets.
 
My blued 4 5/8" SBH likes:

240-250gr cast + 5grs Bullseye
240-250gr cast + 10grs Unique
300gr cast + 9.5grs AA #2
310gr WFNGC + 21.0grs H110 - this one's bad news
310gr WFNCG + 9.5grs Unique
240 XTP + 19.0grs 2400
240 XTP + 24.0grs H110
300gr Sierra + 15grs 2400


My factory sights work with all loads.


My barrel has been fire lapped and I get no leading on any of those loads. All shoot better than I can.
