Kidd Supergrade Accuracy issues

I purchased a pre-owned Kidd Supergrade setup early this year and just recently started to shoot it some. I have had it in three different stocks now (KRG Bravo, Tony Mele, and Victor Titan). I have the rear anchor and can use it in all three stocks. I don't get the accuracy I get from a Kidd Barrel/Ruger receiver build that is at least 12 years old. My supergrade purchase included 2 barrels, a 20" stainless HB and an 18" Black fluted and threaded HB. These are the new setup with easy barrel swap.

Anyway, I have tried lots of different ammo including SK Std, SK Rifle Match, SK Long Range, RWS Rifle Match, RWS Special Match, Eley Semi-auto, SK Pistol Match and probably some others I have forgotten. I occasionally get the "that's what I'm looking for" groups, but for the most part I don't get the consistent accuracy I am expecting from a Supergrade setup.

Right now I am using the Titan (That's what my other Kidd/Ruger setup does amazing in). I have the action screw torqued to 20 in-lbs and have tried different tensions on the rear anchor ranging from just snug to 20 in-lbs. When I go with the higher torque rear tension the rear of the action quite obviously pulls into the stock and I've wondered if I'm putting the action into a bind.

I do want to say I reached out to Kidd even though this was a pre-owned purchase and they have already offered to replace a barrel or look at the rifle to help me, which I think is incredible customer service.

I'm sure it's possible to have a bad barrel, but probably not two. Before I take them up on their offer, I'd like to see if I can figure something out and get this rifle to shoot like I know it should.

Thanks for reading this far...any suggestions?

John

What is your cleaning process for your barrels?

What scope/mount?

My supergrades were inconsistent in the accuracy department swapping barrels until I bought KIDD's torque screwdriver for tightening the quick disconnect barrel screws. I was ready to send back an ultralight barrel as it would barely group better than .75" at 50 when installed by hand torque. Once I bought and started using the torque driver, groups shrank by half, well under KIDD's guarantee of .500" at 50. The other two barrels also became more consistent even though they were all ready better shooting than guarantee.

Thought my supergrades were kind of overpriced/overhyped prior to getting the toque driver. But once I started using it then the supergrades became very satisfying.

Wolf--that's pretty amazing that the torgue on the barrel mounting screws could have THAT much effect on grouping

Just a question for other (the "quick disconnect" versions) SuperGrade owners: have any of you seen anything that mirrors Wolfshoon's experience regarding torque settings on the barrel mounting screws? Just curious is all... For a very reasonable $25 investment, that is a huge reduction in group sizes.

Thanks for the replies

Thank you for the replies so far.

I actually have the Kidd torque driver and make sure to use it when I switch the barrels.

My cleaning process is pretty basic. With the Supergrade, I remove the barrel prior to cleaning. Then I run several Kroil soaked patches down the barrel until the patch doesn't show any residue. Then several dry patches until clean. This has served me well with other rifles and I'm fairly certain I got that routine from someone here on RFC, but don't remember who posted it. I also clean the chamber with a nylon brush on a short rod.

I have played a little bit with torque and the groups seem to tighten some if I tighten the rear anchor screw to 20-25 in-lbs.

My great shooting setup has a Volquartsen action screw and this one does not, so I ordered a VQ action screw to remove that variable. I'm going to wait until it arrives before chasing anything else. Hopefully it arrives before the weekend and I can make it to the range again.

Thanks again for the input.

Forgot the scope

I have tried two different scopes so far. A Weaver T36 and a Weaver V16. Both are mounted with Weaver rings on the Picatinny rail attached to the receiver. I torque the scope mount screws to 20 in-lbs when I mount the scope.

Sounds like you are doing all your cleaning right, but I can't tell from the quote above whether you are concentrating on the dreaded Carbon Ring or not. Make sure you give the chamber area a good soak for 15-20 minutes with Kroil or you favorite bore cleaner (it can be applied to the chamber area with a Q-tip) and then hit the chamber with your cleaning brush after doing that soak, if you are not doing it that way already. The carbon ring can be a beast with regards to accuracy, but at least it is easy enough to remove if you specifically go after it once in awhile. Good luck with your experiments.

I was thinking carbon ring as well. If it was just one barrel not shooting to expectations from Kidd then maybe you could chaulk it up to a bad barrel, but the odds of two Kidd barrels being bad has to be pretty low. It's possible (not accusing anyone of anything nefarious) that the original owner sold it because they started having accuracy issues.

Lots of people think they're doing a great job cleaning and don't even consider the fact that they could have a carbon ring, especially when they're pulling clean patches. I had this happen to me long ago with a Kidd barrel. I couldn't understand how it went from being a tack driver to meh when I hadn't changed anything and was regularly cleaning. Turns out I wasn't paying enough attention to the chamber. Got a chamber cleaning tool and haven't had that issue ever since, after a lot of soaking and elbow grease to remove the carbon ring.

Two points:

Every time I've used Kroil to clean a barrel, it has taken most of a box of ammo to settle back down.

Kroil may be able to remove a carbon ring if you soak it long enough, but BoreTech Carbon remover or Rimfire blend will get it done in about 5 minutes.
You may need to use a Bronze brush, or a VFG Super intensive Pellet to get it out depending on how baked it is.

So stop using Kroil, and hit the chamber with a carbon cleaner using a bronze bush or a VFG pellet.
I predict the you will be surprised how dirty your next patches will be.

How do I know all of this?
By using my Hawkeye bore scope, and my 8 years of experience with my Kidd Supergrade.
And by the experiences of others whom I've told to do the same.

By the way I use 10 inch pounds on the rear tang and 15 on the action screw. More than that diminishes accuracy.
Now my McMillan stock will be different than yours, so keep that in mind.

I have 15,186 rounds down the pipe of my 2014 SG.
Here is a very recent target shot with it.
