Yes, I have shot the Timney and Kidd. In fact, I've shot, tested, owned most of the better name triggers out there. The Kidd is head and shoulders above the rest. What you really have to understand about rimfire is that rimfire is not like centerfire. When it comes to rimfire you do have to spend the money to get the best and the best is noticeably better than the rest.
The advise that I conveyed came as a result of a very stupid venture that I embarked upon not long ago. I got into shooting a local benchrest competition. It takes place every Saturday morning and is meant to be open to everyone, so the guy that runs the shoot made it a rule that everyone has to shoot supplied Wolf Match Target ammunition. Inspite of the ammunition requirement, the match and its participants evolved. The other guys were shooting the likes of 54 action Anschutz, Remington 40X, Turbo and Time Precision and I'm not talking bone stock rifles either.
Just to go against the grain, I announced that I was going to shoot the matches with a 10/22 and I was going to do it from a bipod. Most guys laughed at me and all said that I was wasting my time. The match that we shoot consists of shooting a total of 75 rounds at three ARA target cards of 25 targets each, at 50 yards, with an additional 25 rounds which could be used for sighters. A perfect score would be 7500.
After much work and experimentation with my 10/22, I got to where I was regularly shooting in the 6900s. I also posted a few scores over 7000. On one occassion I was able to shoot a 7200, which is, from what I've been told, a range record with a 10/22.
So...I'm just basing what I'm saying on my experiences.
You must also understand that a good shooting 10/22 is more than just a conglomeration of parts. The assembly and tweaking of the screws plays a big part in the accuracy potential of a 10/22. The bedding is also very important. Not so much for just shooting groups, but it plays a pretty big part in consistency when you are shooting in an event that requires a lot of going from one target to another. This is why I suggested a receiver with an attachment point at the rear. It makes getting a solid bedding easier to attain, although I was able to do it with a more conventional receiver without the rear attachment point.
In hind sight, I could have saved myself a lot of time, blood, sweat and tears by just going with the supermatch receiver.
Of course, what I advised only helps to increase your chances of success. I have seen a few $3500 rifles (bolt actions included) that just didn't shoot as well as the owner hoped it would. Still, when you use quality components it becomes less of a crap shoot.
If you just have a bug and insist on building it yourself, get the components that I mentioned above. If you just want a killer 10/22 and have the wallet to finance it, call Tony Kidd at coolguyguns.com and sit back and wait for it to arrive.
I do have to admit that my build isn't sporting a Lilja barrel. I'm running a Kidd 18" and got pretty good results. I was going to get a Lilja to see if I could push it even further, but sanity set in and for about the same amount of money that I had into the 10/22, I got into a Remington 40X in a McMillan stock. During practices, shooting 2450 or 2500 out of 2500 is common place. As it turns out, everyone was right and I was just being stubborn.
Of course, I do have a killer 10/22 and when the need for it arises, I doubt that there will be many semi autos that can keep up with it. Still, dollar for dollar, you get more accuracy out of a good bolt gun. I'm not trying to get off on a tangent here, but (and this is just my opinion) some guys, like me, get obsessed about something and fail to recognize that there is just a better way of doing things. If the utmost in accuracy is what you're after, you're barking up the wrong tree with the 10/22.
With my 10/22, shooting one ragged whole (as many people like to claim) was not hard to do. The question then becomes, how big is that one ragged hole. My 40X, when shooting for a group, will often put three to five rounds through nearly the same bullet hole at 50. Of course, my 40X weighs 12lbs and my 10/22 weighs 9.
