The other day I took off to the range and decided to play with my new chronograph. I am an avid handloader and my intention is to collect data on my handloads as well as some of my muzzleloading guns but it is fun to see what the real world numbers of the rimfires do.

I used two Ruger handguns. A Single Six single action revolver with a 5 1/2 inch barrel and Williams Fire Sights and a Ruger Mark 3/45 autoloader with standard factory iron sights. It too has a 5 1/2 inch barrel. I will post the comparative velocities and accuracy results.

So there you have it. The range was at 25 yards and using an MTM pistol rest on a bench. I did notice that I can shoot better with the Ruger Single Six and the aftermarket Firesights. The standard iron sights on the Mark 3 are a tad fuzzy. I guess that happens when you are at 47. One nice thing about the Ruger autoloader is that it came with a scope base that can be attached to the reciever of the gun. If I had a spare pistol scope I'd mount it to see what the true accuracy potential is. Also, I noticed the velocity difference between the autoloader and the revolver. We all know that the revolver has a cylinder gap but the Ruger gap seems to appear much larger. I did not measure it but I suspect it is over the standard 6 thousandths. I was surprised to see that the difference in velocity with the ammunition that produces lower velocities is not that much between the two guns. It is very evident when the velocity approaches the sound barrier level. The next time I may test the velocities out of the TC Contender Super 16" stainless 22 lr barrel. It will be interesting to say the least.

I have chrono'd my .22's on several occasions, too.
Here are a few old entries I dug up.
I don't play with different brands of ammo much, the Federal bulk has been the most accurate for me so far.

1/1/2010, 50° F, SW617, 6", Federal Bulk 36gr HP, plated
1064 1077 1038 1033 1028 912 998 1023 1010 1048


6/26/2011, 95°, 22/45, 4", Federal Bulk 36gr HP, plated
920 981 1036 968 957 992 977 975
959 1004

I am about to head out the door to chrono some .45 loads.
I'll take a 3" SW with me and run some .22's over the chrono.
If I remember, I'll post them later.

I chronoed 1 shot out of my Ruger Mk III 5.5" at 1010 awhile back--FWIW.

oh sorry--Fed 36 gr. Plated HP bulk pack

Steve, that is about what I am consistently getting from my MK II'a with 6" barrels with the Rem bulk ammo.
