Semi Auto action accuracy, does the action matter?

[LHH]

Target pistols like Walther GSP, Hammerli, Pardini, and others have excellent track records for accuracy.
Comparing pistol actions to rifle actions like a high grade 10/22 from Volquartsen, Kidd or similar does any accuracy advantage exist for a certain type of semi-auto action?
Assuming action is checked/blueprinted like a bolt action, chamber, barrel, and everything being equal would either had any advantage for 22LR?

Looking for accuracy???
1--Buy a empty receiver, custom, built in scope rail, threaded for barrel.
2--Competition bolt.
3--Kidd trigger.
4--Stock to suit, floated barrel, bedded 2" next to receiver, receiver bedded in stock with Marine Tex.
5--Most expensive scope you can afford..If you will be shooting varying range on the clock get a ballistic reticle matching the ammo of choice.
6--Fedderson barrel 20" with Benz chamber.
OR buy a build by Kidd.

That worked for me. Barrelled action bedded in a Boyds.

Thanks for the comments, Kidd rifles are very good. However, my question is about the importance of the action.
A rifle based on the Walther GSP pistol action is what caused me to wonder about the value of the action.

Good question. I wondered how the stock/magazine/trigger would be managed. Couldn't tell a lot about that in the video.
Per the link, it looks pretty straight forward with that pistol - mag is forward to start with.

Ever see anyone shooting a semi auto in a national Benchrest Match? Even on the odd chance you did, has anyone ever won a National Benchrest match it one?

 

[LHH]

Thanks, not comparing to benchrest. I understand semi auto are not as accurate.
The question is just about semi-auto actions and the impact the action may or may not have on overall accuracy. Is a lightweight pistol action as accurate as a heavier rifle action? Both cycle the action and are blowback actions in almost all cases.
In the AR world, all-actions are basically the same, so it's hard to find a comparison that makes sense.

To the OP,.. the "Lock Time" and the "rigidness" of, the Action, is WHY, the Bolt action, is better/ superior than, semi-auto's but, they can, come, "close" !
The quality and "precision" of, the Chamber, Head Space, Barrel, bedding, etc. are one of, the biggest reasons, why "some" .22 LR semi's like, the Custom 10-22 Ruger's / Kidd's / Volqt's, etc. CAN shoot real "well" but, like stated above, they will NOT, win,.. a Bench Rest, Championship !
Example of a quality, "lock Time" Bolt action, would be, the Rem 700 action vs the SLOWER, Winchester Model 70 action,. WHEN was the last time that, you ever saw, a Model 70 shoot, "Bench Rest, quality",.. "Winning", Groups, the 1950's ? maybe ? The Rem 700 action, HAS one of, the BEST ( fastest ) "lock Times", produced.
Before every, Model 70 owner, on the Planet, jumps on me, I will say that, they are, FINE as, "Hunting Rifles" ! This, comparison is used as, an "Example", only.
Hope this, answers the OP's,.. question.

One won't see one because I don't believe they are allowed. Very serious semi-autos, while likely not as accurate as the best bolt-actions - can have a serious advantage in very windy conditions. Enough so to overcome the accuracy differential under the worst of swirling conditions. Also why not allowed in bench rest and other matches. I have been ground squirrel shooting lots of times in extreme weather using an AR-15 (perhaps 1/3" MOA accuracy potential) while my partners used VERY accurate bolt guns, capable of much better. I'd fare no better - and often worse on the first shot - but from then on - there was no comparison. You just couldn't get the rounds off fast enough in a bolt gun to keep pace with the wind movements. That is amplified with a rimfire. I think the biggest factors on a rimfire, assuming a good barrel and optics are SOLID, stress-free receiver/stock mating, having a suitable chamber, mass in the receiver and a good trigger. AR receivers are NOT all the same, either. Some more expensive actions have receiver walls literally twice as thick as a standard AR-15 and are usually machined from a solid billet of aircraft grade aluminum. There are a few companies that make them. I own one such action made by a now-defunct company called Anarchy Arms and the added mass helps to keep the vibes under control - or so it seems. Definitely more rigid. Crazy-accurate gun. Most actions do all look the same from the exterior, though.

I just saw they still have a web page. I called and they still have receivers left - though they closed their store. $450.00 for matched heavy-wall upper and lower.

LHH,
I have a Kidd Supergrade. The Kidd action with their rear anchor is the best action, It has 2 action screws and Kidd's 2 stage trigger, it changes the lock time, making very close to a bolt gun. I have mine in a Titan stock with Titan's rear anchor for their stock. I have a Tikka T1X and a CZ 455 that are very accurate, but the Kidd will edge out by a little.

I looked at a 455 heavy barrel in a Boyd's stock today at LGS, what kind of accuracy are you getting, if you don't mind answering.

Mine is a HB varmint. I replaced the trigger spring ( YoDave ) it's around a 1lb now. It will run MOA with most target ammo. It will run 1/2 moa with match ammo, like wolf match Extra, Eley Club, Center X and SK match rifle.

Thanks for the info.

All the 22lr benchrest organizations allow semi autos.

Do they allow mags? Force single loading?

 

[VLNBYR]

Mags are fine. Mostly the only restrictions are weights in IR50/50 three gun.

There is also a dedicated br assn. for auto loaders. ABRA

If you really want to know the answer to this question ask Joe Chacon. He is the founder of the afore mentioned ABRA and is most time the national champion at the end of the year. He also builds the best rifles in the semi-auto benchrest world. From my limited view on the inter net it looks as if most of the rifles he builds are 10-22s, but he mentions that the Remington semi-auto can be tuned to win in the factory class. If anyone has done the home work to know which semi has the best potential it would be him or he would know where to send you. Good luck!!!
