Ruger SR1911 Ransom Rest Accuracy Test

[Mr.Revolverguy]

Most of you know I wrote a review for the Ruger SR1911 here.

After this review I received a few emails asking if I could shoot the SR1911 from a rest of some sort.

Well here is the follow up SR1911 Ransom Rest Accuracy Test

Awesome!

1.5" at 25 yards using 4.8 gr of W231 with 230 gr X-Treme bullet. Perhaps better accuracy with slightly higher charge of 5.0+ gr?

Thanks for posting. Great pistol.

Bill must be rollin' over in his grave. Good for them continuing to advance that company. I didn't even know about this pistol - thanks for the heads up and links.

That seems to remove any doubt about the mechanical accuracy of the gun itself. It ought to do about as well with at least some factory ammo.

It seems to be displaying a little of the "4+1 syndrome," i.e., four shots clustered tightly with one slightly away from the main group. Was the "flyer" the first shot of the group?

 

[Mr.Revolverguy]

The flyer was the first shot of the group. But I am not sure that if it is gun related or my reloads caused it. Though I have been reloading 45ACP for 18 years some would argue I am not using the highest quality bullet. These are plated not jacketed. But if cheaper plated would get this sort of results I am sure jacketed would turn in the same or better.

 

[chuckles]

Thanks, I have that on my list, along with 47 other guns, but it's there.

The flyer was the first shot of the group. But I am not sure that if it is gun related or my reloads caused it.

It is most likely gun-related. Somehow, the moving parts align themselves a little differently for the first (hand chambered) round, than when the parts move at full speed when the gun is fired. It also largely disappears, I am told, as the gun breaks in. But that tiny divergence is really of no moment, except to give gun scribblers (and me) something to BS about. The tight clustering is what is most impressive. And, you would not likely have found this without the machine rest.

Now if only we could all duplicate this without the rest

 

[Lateck]

It's funny that many never gave the Ruger much respect...

I have know the gun was better then me..

Mr.Revolverguy; thanks for the post.

Lateck,

 

[ColtPythonElite]

That is impressive.

 

[Husker_Fan]

Very cool. Wouldn't that group be 1.05 in? I thought you were supposed to subtract a bullet diameter if you were measuring outside edge to outside edge.

 

[Mr.Revolverguy]

Yes you are right. Posting on the net brings a lot of criticism and some may not understand the proper measurement which may lead to questions of me trying to by biased for Ruger. So I just posted worst case scenario.

Thanks for the write-up. Interesting that it confirms the design/development work Ruger put into the manufacture of the gun

I'm a little disappointed in the 15 yard group, but I'm not sure why you'd be astounded by <1.5" at 25 yards...that would only extrapolate out to ~3" at 50 yards. Out of a Ransom rest, I would expect ~ 2" groups at 50 yards

Like TLH, I suspected the first round was the flyer of the group...it is pretty universal in autoloaders...and is likely mostly gun related when it is the first round

 

[Mr.Revolverguy]

For a production 1911 I believe 1.5inches is really well. If I had took the proper measurements it would really be about 1inch but I am not splitting hairs. I probably should have stated 1.5inches for me and what Ruger classifies as a defensive handgun meets my needs. I may even go back and change the article. Sorry I am from the camp of past 25 yards I will be using my carbine or long gun.

 

[9mmepiphany]

Sorry I am from the camp of past 25 yards I will be using my carbine or long gun.

I understand what you mean.

The standard distance for testing with a Ransom Rest is just 50 yards, because it is so stable that it takes that distance to start seeing the difference that fitting of the gun makes. That is why Les Baer has the option of their 1.5" @ 50 yards guns...also why the minimum acceptable accuracy for a combat gun is often given as 4" at 50 yards from a rollover prone

 

[The Lone Haranguer]

I could even live with "#3 washtub at 50 yards" (as Col. Askins used to say) accuracy if it goes bang every time. Suffice it to say, the Ruger 1911 ( at least this particular sample, with that load) is plenty accurate.
