Ruger Blackhawk .327 Mag Range Review

I just got a new-to-me Ruger Blackhawk in .327 magnum. I had thought about getting one over the last year or so and then the gun craziness hit in November. Anyway, I looked on the Ruger site to see what the price is now and it was no longer listed. I picked this one up used and here are my opinions for what it is worth. I have single six in .32 H&R and this revolver is just more solid and bigger when you pick it up. The gun weighs about 3 pounds empty and that is part of what makes it so pleasant to shoot as it lessens the felt recoil.

I bought a couple of boxes of Federal 100 grain loads and they clocked out around 1600 FPS or more so that puts the kinetic energy around the 570 ft/lbs range.

The recoil would calculate to be around 5 ft/lbs with this load. For comparison, think of a 2.5 pound pistol in 40 S&W shooting a 180 grain load at 1025 fps would make about 420 ft/lbs of energy and generate about 6 ft/lbs of recoil. In other words, the Ruger makes 150 ft/lbs more energy than the 40 S&W 180 load, 35% more, while the 40 S&W has 20% more felt recoil than the Ruger.

I am old enough to remember when Ruger made a Blackhawk in .357 Maximum. Ruger made the cylinder shorter than the Dan Wesson in the same caliber. Silhouette shooters liked to load 180 and 200 grain bullets which worked fine in the DW but were long for the Ruger. The Ruger owners were shooting a lot more 158 grain bullets and flame cutting was an issue with the light bullets and the Rugers were soon pulled off the market. Someone at Ruger must have remembered this when designing the .327 Blackhawk as the top of the 100 grain load is around 0.245” from the front of the cylinder.

The cylinder will easily handle longer/heavier bullets. I am going to try casting some 115-130 range bullets with gas checks to see if the rifling will handle them.

I adjusted the sights for a 6 o’clock hold at 25 yards. I fired 10 rounds standing with the 100 grain load.

Then I got some of my practice 32 wadcutter loads and tried them. When I shot the first one I stopped and looked through the spotting scope to be sure it cleared the barrel as it felt so light—I thought it was a squib load. They just ARE that light on the recoil and the accuracy was pretty good.

I am going to try some of my match loads to see what they do in the near future. Finally, just to see what it would do, I held 6 o’clock on a target at 50 yards for 5 shots. The group was not the best but it was interesting to see that the gun was hitting higher than at 25 yard as it is still climbing due to the velocity.

I am going to have a lot of fun with this gun!
 
Nice review.
I must disagree with your conclusion about the cylinder length. I bet you will find it to be a standard length cylinder and that no length adjustments were made to accommodate the 327.
 
Cylinder Length

I must disagree with your conclusion about the cylinder length. I bet you will find it to be a standard length cylinder and that no length adjustments were made to accommodate the 327.

A .32 H&R magnum case is about 1.070" long and a .327 magnum case is about 1.200" long or a difference of 0.130". However, the .327 magnum cylinder on the left is 1.645" compared to the .32 H&R magnum cylinder on the right which is 1.405"; a difference of 0.240" or 0.110" net increase in usable loading length. Where did your measurements differ?

Both my New Model Blackhawk in 30 Carbine and my Vaquero in 45 Colt have 1.700" cylinders.
The Vaquero is nothing more than a fixed sighted Blackhawk. The Vaquero is from 1991 and the Blackhawk is a 2010 model.
The cylinders are the same size as a friend's 80s vintage Blackhawk in 41 Magnum.
The 41 Magnum and 30 Carbine share case lengths of 1.290" while the 45 Colt drops a teeny bit to 1.285".

Changing the length of the cylinder by a significant margin would require redesigning the frame of the gun. I don't think Ruger would be too excited about making such an expensive modification to a fine working platform.

You were comparing a smaller Single Six to a full size Blackhawk. If you want a comparison to another large Ruger, the cylinder length of my Super Redhawk in 454 is 1.750".

Saleen- I have the same gun and my observations match yours. I haven't shot .32 longs out of it yet, but they must be like .22s. I would really like to get an 8 3/8 inch Smith 16-4 and have the cylinders bored to .327 length, but the darn things are trading for $1000 plus.
 
I strongly suspect one of these could be easily re-chambered to eight-shot 9mmPara with the stock cylinder. Which would be damned interesting. It would also be (by FAR!) the easiest of the Ruger SAs to convert to gas-powered auto-shell-ejection and magazine feeding. By a huge amount.

The .32s I shot here were just out of my high-tech practice ammo storage container; IE: Cool Whip container :). I have some very accurate .32 longs I shoot from my Benellis and FAS and I am going to do some testing at 25 and 50 yards with them. I am in the process of getting a set of Ransom rest inserts for the Ruger Blackhawk and I will see what I can do with the .32s.

Those must be California only calibers. In Pennsylvania, the .32s we have are in the .312 - .314 range while our backwoods 9mms are in the .356 range. While you may class that as "damned interesting", I am thinking it may be more dangerous than interesting. Your gas-powered-auto-shell-ejection; et al, must be something the forward thinking gun lobby out of CA is coming up with. We are behind the times here according to President Obama. :rolleyes:
 
No, I'm just bonkers :). I actually converted a NewVaq357 into a true 9mmPara with magazine feeding and automatic gas-powered ejection of empty shells. It all barely fits. Your gun would be a much easier platform to do this stunt with :).

The comments I posted on youtube are fairly long and detail a lot about how it was built. No other personal arm ever made uses the same feed cycle that I know of.

:D
 
Sorry!

Sorry brother, I thought you were pulling my leg!! I never heard of that before. I will have to check it out. :o
 
It's my own invention. The only thing out there with a similar feed cycle is the US M39 series 20mm and 30mm autocannons used on some early jet fighters. They had five-shot cylinders and a single barrel, and used a mechanical shell ramming system to feed from a more conventional mag arrangement (like a semi-auto handgun mag but way bigger and flexible). They used gas-powered shell ejection. I know the F86 Saberjet had at least one, maybe two.

The M39 design was taken from a captured late-war Nazi prototype, the Mauser M213, also a 20mm. So far as I know this feed cycle has never been used in a personal weapon of any sort, handgun shotgun or rifle.

I found out about the M39 and M213 when I was about halfway through building Maurice, when I had gas-powered shell ejection working in 357Magnum. I had already planned the conversion to 9mm and magazine feeding and was talking about it when somebody pointed those guns out.
 
I have one of those on my list. I think it would make an awesome, fur-friendly trapline gun with cast bullets with enough juice to whack a wolf quickly, and make short work of smaller critters without messing up the pelts.
 
.327 Magnum

Will do, Sir. I have not loaded any .327s yet but have done a lot with .32 S&W longs for my competition guns. I did order two bullet molds. They are actually .30 caliber rifle molds, a 115 FP and 130 RN, for gas check bullets. I have two of their bigger brothers and they both come out at .312 without sizing so I think they will work. I will post the results.
