Myke, you seem to be a disputatious fellow at best and I've often asked you quit making a nuisance of yourself. Perhaps your dogged criticism fulfills a need that psychologists could explain. No matter, I find it difficult to take you seriously as you blow hot and cold. Perhaps its too much homemade. I really don't know. But if you want to fight, get married or join the army. Both offer better opportunities for battling real and imagined foes than I will. I don't want to fight with you.
In any case, I'm not jumping on anyone, least of all you so don't take this the wrong way -- if that's possible. I'm trying to note how exceptional a factory sporter must be to achieve such notable results with non-match ammo, an achievement that may impress and astonish a lot of shooters.
But seeing as you can't resist not only following me around when I post here and RFC but challenging my views at every opportunity, why don't you offer an explanation why CCI ammo has a better ES than many match ammos? Maybe it does. Maybe this is an unusually good batch of CCI Subsonic HP ammo. I don't shoot CCI ammo and perhaps you can shed some light. In any event, a low ES is necessary for 3 - 4.5" ten shot groups at 200 yards regardless of the rifle and shooter. Ammo with an ES greater than 50 fps cannot achieve such groups at 200 yards even with a perfect rifle and perfect shooting. There's no way around that.
Regarding the the Tikka T1X and the Vudoo, you say "I don't understand why the comparison was even brought up." The reason is simple, so it's hard to see why you don't understand. I'll explain.
The Tikka was said to shoot ten shot groups outdoors at 50 yards with CCI that were under .500". I think that's a commendable achievement. Incredible and extraordinary were the words I used. I said many shooters "would be overjoyed to shoot consistent sub-.5" five-shot-groups with CCI at 50 yards." I stand by that.
To put the Tikka TIX's ten shot groups in perspective, I compared it in an earlier post with the standard Anschutz supposedly has for its rifles' ten shot groups. Anschutz puts the barreled actions in a vise and shoots in an indoor test tunnel. The Anschutz ten shot groups must be no larger than 18mm (.709") at 50 yards or the rifle is sent back to the factory for further work.
To add further perspective, I offered the comparison with the much-talked-about Vudoo rifle. On RFC, the designer and maker of the Vudoo rifle, posting under the name RAVAGE, said that the Vudoo was tested at the Lapua testing facility (presumably the one in Mesa, Arizona). In the indoor test tunnel in a specially made fixture or vise, the Vudoo shot what RAVAGE believed was that facility's indoor test tunnel record of the smallest ten shot group at 50 yards up to that time which was "less than" 13mm (or .512"). This measurement was outside edge measured, as confirmed by RAVAGE just today on RFC. (See h t t p s://www.rimfirecentral.com/forums/showpost.php?p=11669853&postcount=91 )
I think it's remarkable that a sporter shot outdoors with CCI ammo achieve results close to those achieved by a Vudoo clamped in a vise shooting indoors with match ammo. That is why I made the comparison -- to put things in perspective. I don't know about other test facility records and they aren't at issue here.
Most if not all of my CZ .22 FS rifles shoot .5” at 50 ten shot groups, to be honest if that don’t do that or near with the ammo they like the most I sell them. If you take a look at the CCI subsonic 40 grain lead hollow point reviews online you will see it outshoots a lot of match ammo. It’s a pretty consistent ammunition some of my other rifles won’t shoot it well but the tikka likes it a lot. As for the 200 yard target I would wager I can shrink those groups on a nice calm warm day.
