I have been asked to include the Ransom Rest in more video's for accuracy testing. So what better pistol to test with then the Lipsey's Exclusive Ruger Blackhawk 10MM Conversion in 10MM & 40S&W. Today I used three different loads to test with 200gr, 175grSWC and 135gr Nosler JHP.

The Ransom Rest is a great device for accuracy testing like what I have conducted in this video, but I use it to make me a better reloader.

Stay tuned for the next video as we compare 10MM velocity from the Ruger Blackhawk against other pistols with different barrel lengths.

I am still in amazement with how soft shooting the beefy blackhawk really is in 10MM.

Do you all think it is the twist rate if the barrel impacting the accuracy with heavier loads?

MRG,

Thanks for taking the time to share these experiences with us.  I really appreciate your low stress information delivery.  I also appreciate the chance to see how you are working the Ransom. 

I want to share two comments I have after watching to the end.  First ... you are KILLING me.  Seeing your reaction to each shot but having to wait till the end of the video to see the paper ranks right up there with oral surgery.  I will absolutely do another drive by to thank you if try to edit in pictures of groups after you shoot them - or, maybe a target cam and picture in picture magic to bring us the developing group as you shoot  8).

Second ... I understand I'm trying to spend your money, but ... I would learn a lot more if you tested with ammo I know.  I can't compare the performance with anything in my stable 'cause I don't shoot your loads.  I think you need a good ammo sponsorship.  I wonder if any of the boutiques are run by personalities brave enough to let you perform such unbiased testing.

I'll be watching for the 10mm content and I look forward to my just scheduled drive-by.

Dred,

You have me ROFL this morning.

Yeah I made a bad mistake I am no camera professional and end up trying to setup the stuff myself. My target camera is an old Iphone and guess what I went to power it up and no battery and I didn't notice that it was dead until the second grouping when I went down range and it had only captured the first 3 shots. I was so excited about being on the range with the Ruger I overlooked some of the small details all fair criticism. In other video's I have followed your exact recommendation.

Scarlett,

I am not even sure what the twist rate is. It would surprise me if it is anything different than 1 in 16 which should do fine with the heavier bullets. I have reached out to Lipsey's and Ruger to see if I can get an answer to this question.

It'll be interesting to hear what they say. Thank you for the effort. I made a little series of videos for smithing CZ pistols and I'm definitely not a professional videographer either. They take lots of work. Yours look great and with more great feedback I'm sure they'll just keep getting better. Most importantly they are about 10mm's!

Point me to your CZ video's love those also :) If not 10MM related send me a private message.

I am very interested in the velocity comparisons. I always have wondered what loss the gap accounts for? Most custom builders really tighten the gap to minimize this. This will be interesting. Thanks for sharing with us.

Nothing wrong with that 175 and 200 grain accuracy for a load that is just "book" and has not been tuned to the pistol.  I would be surprised if a little load work wouldn't shrink those groups by at least half.

I think the 135 load just lucked into a sweet spot more than anything else.

Ramjet,

Another good idea. Do you think it would be a fair comparison to take a 6inch 1911 against the 6inch blackhawk. That's of course fi I can get my hands on a 6inch 1911 in 10MM. I know Remington and Para made one. I will put out the feelers to see if I could compare.

I know I'm responding out of turn.  But ... no, I don't think 6" 1911 compares to a 6" revolver.  They are measured using different conventions.  The 6" revolver barrel is actually 7.25"+ (substituting cartridge length for actual cylinder measurement) by autoloader measurement convention because an autoloader measurement includes the chamber as well.

That said ... if  you film it, I will watch.  One day I'll line up a 5" Coonan against a 3.5 to 4" revolver - 'cause I'll use any excuse necessary to justify a Coonan (wanted one forever, but it hasn't been "most wanted" yet).

Tell me about the coonan I agree.

On the comparison it is as close as us mortals can come in discussing cylinder gap vs no cylinder gap :)

I appreciate the feedback I guess I am no scientist or camera man but though a lot of this is about FUN heheheheheh. Thought I will do my best Dred.

I think 6" vs 6" as long as you define the actual measurement criteria. In other words including the chamber or not. So measure the barrel length by measuring the length from the case primer to the end of the barrel and state that clearly on each gun.   Load for load comparison we can gleen what we want from your listed data.

It could be comparative yet the revolver will have slightly more barrel length because of the cylinder but may loose velocity because of the gap and in essence be neck and neck with the 1911 6" long slide version.

It's all interesting stuff. Heck you can change recoil springs on a Glock and get different velocities from the same load same gun just the spring rates are different. Now put a tight chamber aftermarket barrel on and get a different result.

Just a comparison of the said weapons as defined by a consistent measurement process.

Too bad you do not have a model 20 I would and you a LW aftermarket barrel that is 6.25" to use for testing.
