Semi Auto action accuracy, does the action matter?

perfect, will send Joe an email.

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?

Study your history. A 10-22 was used to win the US National Silhouette Smallbore Championship years back. Joe Chacon has shot a 10-22 in national level 22 rimfire BR competitions, and won a target.

so does any of that make them well suited or common?

Defending your ignorance by moving the goalposts is comical

Anther blowhard no it all for the ignore list....

That would be “Know it all”. Crack-up in LasCruces ?

In your response to Dryfly regarding his asking if anyone won a national Benchrest match with a semi auto, you gave Silhouette as an example. Silhouette is lot different than Benchrest (its an apples to oranges comparison).

Did you not read the rest of my statement of fact ? National level rimfire benchrest match, Joe Chacon winning one target outright and placing 40 th overall out of some 200 shooters with proper bolt action rimfire rigs, using a 10-22 is exactly apples to apples. This fact led dryfly to become triggered, launching an ad hominem attack, rather than examine or verify these facts. As he has taken down his posts and gone away, I consider the matter dead.

The real issue with semi-auto 22lr precision, is even if you get one that is truly competitive, they won't stay that way for more than a few hundred rounds. 200-400 in my experience. After that, the action requires a complete tear down and cleaning. The timing of the action and how it affects harmonics and ignition, just seems to change too radically, and much too often. I had a lot of spare-no-expense 10/22's, including kidd complete builds, and they were fun. Nowhere near what my bolt guns are capable of however.

Orkan, you are partially correct. The early Kidd custom guns used an incredibly tight Eley chamber and did require brushing the chamber and lead ring about every 200 rounds else a round would eventually fail to fully seat. A work-around for that was found, extending the tear-down cycle to several thousand rounds, and from the fact that accuracy increased toward the end of that cycle, you might guess what the fix was. The bolt needs to square to the breech on chambering a round, the same every time. There is no assurance of this even in the custom actions, and “spare no expense” builds, thus some hand fitting/ shimming is typically required. They respond well to tuners, despite the monkey motion. It is up to the individual to decide if the extra work involved is worth the trouble. It is fair to say the bolt guns and ammo have also improved, perhaps widening the accuracy gap

Some interest in my club in semi auto 22's accuracy..One of the members has started a match.... Any semi auto,no restrictions on weight, sight, stock, ammo, make. Just bring your best game.
Three targets 10 rounds each-all same at 100 yds ..round bull app 2" ten ring with red center 1"for an 11 count. Trial match was won with a Ruger sporting a Fedderson 16" barrel..Score was 311 out of possible 333.
The shooter had asked guess who for barrel recommendation...My good..

Please don't mistake my statement of fact as a request for validation. This isn't a topic I intend to argue beyond statements of fact. In my most recent bolt gun build, I'm sitting at over 3,200 rounds of 1/4" or better @ 50yds performance. I've not cleaned the barrel in any way, and only cleaned the bolt face due to a single ejection failure on the plus side of 3,000 rounds. I'm aware of no semi-auto of any make or model that can match or even approach that level of reliable performance. If I see 30% or more of shooters at national level 22lr events using and being competitive with semi autos, perhaps it would be worth talking about. However, that is not happening. Instead, almost no semi autos are present... and in the chance that someone scores 40th place with one, it gets used as a lightning rod to mislead shooters into thinking fielding a semi-auto is a viable idea. It's not presently a viable idea. If shooting in the .4's to .6's on the regular is the metric for success, then a semi auto can certainly do it.

Semi auto's have a place, and I do like them for their strengths. If someone is looking for the ultimate in precision and accuracy in 22lr, you won't easily or repeatably find it in a semi-auto. I don't intend on arguing that fact, and I hope any uninitiated shooters reading this will consider my words and their goals carefully before investing in a semi auto.

Back to the original question and a possible answer:
The original question was not about semi-auto vs bolt action in terms of accuracy.
I think everyone agrees bolt actions are more accurate.
The original question was regarding a pistol semi-auto action vs a rifle semi-auto action in terms of accuracy. Would a pistol action converted to a rifle have any shortcomings compared to a rifle action? Example: 10/22 action vs a Mk IV pistol action, assuming both have the same chamber, barrel and so on, does having a heavier rifle action make a measurable difference in accuracy? In the bolt action world, stiffer/heavier is considered better for the most part. I wondered if this applied to semi-autos as well.
Answers:
Joe Chacon thinks no, likely does not make any difference
Earl's Walther repair same answer

The question came up as Olympic target(semi-auto)pistols in 22LR, 32 S&W long and a few 38 specials are exempt from normal California gun restrictions.

I never wrote Chacon winning was apples to oranges, I wrote comparing silhouette to benchrest was apples to oranges
