I finally got a chance to shoot my .45 ACP cylinder on my 4 5/8" Blackhawk today. I was shooting white box Winchester 230 grain FMJ ammo and some left over 230 grain Gold Dot.
We have been doing some clearing of storm damage on our land and there are many large piles of brush with the sawed ends of pine logs showing on the ends of the piles. A lot of these logs are about the diameter of a coffee can and the sawed ends are perfect targets at odd distances in the woods, plus there is an unlimited number of them.
My son and I shot them until we ran out of ammo and then started in with the .22 Colt Frontier Scout pistol.
The Blackhawk performed perfectly. I was able to hit a four to six inch log end every time at almost any distance I tried if I aimed carefully. Many of the groups were quite small and I actually had to look hard to tell one hole from another. Just before running out of ammo were were amusing ourselves by shooting thumb size limbs off of pine logs at 15 yards. Recoil was extremely mild. I do not remember enjoying shooting a revolver as much as this in the recent past. Recoil, balance and accuracy were perfect for a pistol this size.
I must say I was impressed by the performance of the .45 Colt cylinder on this pistol. It is as accurate as my 7.5" .45 Colt Blackhawk and only gives up a little velocity wise. However, the .45 ACP cylinder is every bit as accurate and even shoots close to the same point of aim at reasonable distances. Add to that an almost unlimited supply of bargin priced .45 ACP ammo at least compared to .45 Colt ammo prices. My son is already asking for a .357/9mm Blackhawk to step up from his .22 Frontier Scout.

I bought a 4-5/8" Blackhawk .45 convertible last fall and my experience has been virtually identical to yours. I've always been more of an auto guy, but I love this gun! Extremely accurate and very gentle to shoot. And with that barrel length, quite easy to tote around too. I'm anxious to get back to my cabin this spring and load some hot .45 Colts to see how it handles those.
 
I picked one of these up in 4 5/8" about five years ago and only recently started shooting it seriously. It absolutely loves my cast Lyman 230 gr. RNLs with 6.5 gr. Unique. If I do my part it will darn put them all into one hole at 15 yards (5 out of 6 last time out, and the flyer was my doing).

Initially I had lousy results with .45 Colt handloads and commercial .452 bullets. I pulled out some of my old .454 dia. Keith SWC handloads for the Colt SAA and it shot them beautifully with no leading. Fortunately I kept my .454 bullet mold and just ran off about 1100 of them which I intend to fire off in this coming year. I use 8.5 gr. Unique with this bullet and it seems to shoot just about as well as the ACP load. I may even try some loads with FFg black powder.

Having a couple of old flat tops around I had trouble getting used to the NM action, and still am not crazy about it (much less the detail stripping of the gun to work on the trigger). But the pistol itself performs so well that I can overlook trivial details.

IMHO this is one of the best packages going. It's a lot of gun for the money.
 
I have several SS NMBH in .45 Colt for which I had Ruger fit a .45 ACP cylinder. Mine have 5 1/2" barrels and shoot .45 Colt and .45 ACP very nicely. I load a 200 SWC with 231 for IPSC, and those rounds that don't gage up properly get shot in my Blackhawk. They shoot in the Blackhawk at least as well as in my 1911, which has a Kart barrel and Bomar sights.
 
I had the cylinder installed several years ago, at a cost of $60 plus installation. I also had barrel changed from 7 1/2" to 5 1/2". Totaled $135 to $140 or so.
The .45 ACP cylinders don't use moon clips. The cartridges headspace on the chamber mouth, and extract and eject with the usual under barrel ejector. They work quite well. What I have seen done is to have the cylinder cut back like a S&W Model 25-2 to allow use of .45 AR cases as well as .45 ACP. I haven't bothered to do that.
 
I have the 5.5" .45 Colt/.45 ACP and I love it. The .45ACP cylinder made it possible for me to shoot a lot until I got into reloading. I had both my cylinders reamed out by Cas at cylindersmith.com and it took care of some flier issues I was having with the .45 Colt cylinder. I probably didn't need to the ACP but I figured what the heck...
 
I have the 4 5/8" Blackhawk in 45 Colt. I can't hit anything with it - shooting some old Bullx 250 gr. bullets I've had sitting around for years. At 50 ft. indoors I'm lucky if I hit the paper with this thing, and I shoot other revolvers (44's/357's) pretty well. It's very uncomfortable for me to shoot too, it really bites my hand. The gun has those white grips on it, someone suggested I should swap the grips out and maybe that would ease the pain. I hadn't shot it before this winter, I tried it out a couple of times after our bullseye matches were done (50 ft range) and quickly switched over to my 44 mags - I shoot those very good. Another suggestion I got was to slug the barrel, that maybe the bullets I'm using aren't the correct size for the gun - I'm pretty sure the bullets are .452. Something was mumbled about 45 Colts being various diameters. I'm going to try and trade it off at a gun show this weekend. It's a nice size gun, I got it thinking it'd be ideal to stick in a holster for walks in the woods - but I might as well be packing a rock given the way I shoot it. It's in excellent condition, never been carried in a holster so the blueing is still great. Any idea what these things are worth?
 
Older .45 Colts tended to have oversize cylinder throats, which can cause severe inaccuracy. Newer ones tend to have undersized throats. If you have a .452" bullet, try it for fit in the cylinder throat. If they are oversize, you are done. If they are undersize, you can send the cylinder out to get the throats recut and evened up at approximately .4525". It can make a world of difference in the accuracy and consistency of the gun. There are more things to do to it, but that is the biggy.
 
Rick, the info from Tom C. makes sense. Originally my Convertible with the .45 Colt cyl. shot poorly with commercial .452 bullets and leaded badly. I ran some old loads for my SAA Colt with the Keith 454424 bullet sized to .454 through it and the accuracy came back and the leading went away. I also sent the cyl. of to be reamed to .4525 and that helped as well.

I still get too much leading from the 230 gr RNL in ACP so perhaps that cylinder ought to be reamed too. Nonetheless the accuracy with the ACP is all I could ask for.

I plan to shoot this gun fairly extensively this summer to see just what it will do, but so far it is holding up its end very well.

Don't give up on that Ruger too soon.
 
anyone got much experience with the 7.5" vesion?


i like the acp cylinder, lots of free brass for light loads, and regular colt brass for the good stuff:evil:
 
I must say I was impressed by the performance of the .45 Colt cylinder on this pistol. It is as accurate as my 7.5" .45 Colt Blackhawk and only gives up a little velocity wise. However, the .45 ACP cylinder is every bit as accurate and even shoots close to the same point of aim at reasonable distances.
I also found this to be true with the "old model" convertible that I had.
 
I have a short barreled .45 Convertible New Model and it rarely ever sees the Colt cylinder. It is amazingly accurate with the ACP cylinder. A great little field gun.
 
If I couldn't hit anything with my .45 Colt Blackhawk, I'd just give up handguns. It's about the most accurate handgun I have excluding my Contender and .22 Mk 2 Ruger.

I guess if you don't handload, the ACP cyllinder would be more useful. ACP brass is plentiful at the range for the scrap brass scrounger like me where Colt brass has to be bought. But, if I wanna shoot .45ACP, I have an accurate auto to shoot it from. I cast a 255 grain flat nose Lee bullet and with 8.3 grains of Unique behind it, it's extremely accurate and mild to shoot. It pushes about 950 fps, in that neighborhood, from my 4 5/8" barrel. I simply lower the rear sight by 6 clicks (marked on the sight) and shoot a 300 grain XTP/JHP at 1120 fps with the same accuracy. I love that gun for outdoor carry. Even at today's primer prices, by scrounging lead, I can load 50 rounds for about 3 bucks. There is no economic incentive to get an ACP cylinder other than the free brass, but Colt brass loaded to SAAMI Colt levels lasts forever. I don't shoot the heavy load much. It's simply for hunting and carry when I might need the power.
 
I have a convertible Bisley Blackhawk that I purchased recently, but I haven't been able to use the .45 ACP cylinder much yet. The throats are so tight (around .450) that if there is any full-diameter bullet extending beyond the case mouth it simply won't chamber. LSWCs, will not come anywhere close to chambering because I've got about a 1/16" shoulder. I'll be getting the throat reamed shortly on both cylinders. The .45 Colt cylinder was a bit better at .451. What ACP rounds I have managed to shoot were certainly enjoyable, as well as fairly accurate despite the small throats.
 
I have 4 SS NMBHs in .45 Colt for which I have gotten .45 ACP cylinders, and a .45 Colt SS Bisley for which Ruger wouldn't fit a .45 ACP cylinder. All the .45 Colt cylinders and several of the .45 ACP cylinders had to be reamed. I had so many to do, I bought the reamer from Brownell's. I have also had to recut the barrel forcing cone on most of them. Combine that stuff with a trigger job and you have a sweet shooting gun.

I have also had the .45 ACP cylinders trimmed to use .45 AR brass. This way I can use the same 200 gr. SWC / 231 loads that I use in my S&W 625JM.

The .357/9mm convertible may not work as well. 9x19mm uses bullets slightly smaller in diameter than .38/.357. Accuracy may suffer.
 
While the accuracy of the 9mm cylinder in a .357 NMBH typically isn't very good, the accuracy of mine with CCI Blazer seems to be nearly as good as the accuracy with .357. The 9mm makes a cheap substitute that I don't need to worry about reloading.
