I guess that settles it. If someone says it, so it must be. Still, it's too bad there are no targets. A lot of folks would like to see a Bergara outshoot Vudoos and Anschutz too.
I'm impressed by the results that Josh at the Pursuit of Accuracy YouTube channel gets with his Lilja barrelled CZ 457. He's installed a good barrel, adjusted headspace, and done lot testing with high-quality ammo. With that, he seems to be getting some very impressive performance out of the rifle which costs much less than an equivalent Vudoo, Rim-X, Ultimatum, etc. He's even getting excellent reliability too.
So, I'm not so sure that the high-end 700-footprint rimfire rifles are necessarily that superior over all the other designs out there when they're properly set up.
The Northern Rimfire Series (Rimfire PRS) 2021 Champion shot a Lilja barreled CZ 455 this season. Mainly Ontario and Quebec shooters in this series.
And CZ is a controlled feed action. In fact, I have yet to see a rimfire that wasn't
Thanks... for me, the 'fancy part' to test would be a barrel tuner. It has been an eye opener for me. Not always needed but when it helps... wowza, it helps.

Well elighten us... which current manf rimfire is a push feed action?

A good number of magazine fed 22LRs are CRF, including one of the more successful of CRF systems, the 10/22. There are some that are considered CRF that are really, Controlled Round Push Feed, like the B14R (yes, it's a thing). As stated, Bergara considers their action to be Push Feed and this is a respectable position due to the true definition of CRF. Single shot 22LRs are generally not CRF.
Someone in the earlier part of this thread made an awesome comment about timing, which is key to proper function. A significant number of magazine fed 22LRs that are CRF suffer from poor timing and therefore, don't work as well as they could. Also, to be true CRF, there has to be an overlap of control between the magazine feed lips and the extractors. This overlap is the duration that both the feed lips and the extractors have control of the round.

With any precision rifle, make or break is the mags and how they function.
OP already has a 452 so mags can be used in the 457 saving time and headache
10/22 mags are also very reliable.

I concur after having built a rifle from a T1x (IBI barrel, KRG Bravo chassis etc). The T1x mags suck to be honest and 2 of the 5 I have cause feeding problems.
Were I to build another it would be from a 457 (I have 2 x 455's but like the bolt throw of the 457)
Fine... but given the context of this post, we don't use single feed actions in this game.
I know much has been made about CRF in a Vudoo.... I am simply pointing out that ALL mag fed rimfires are CRF with some actions doing a very nice job of handling the tasks. If shooters want to debate the 'amount' of CRF, have at it... that level of minutia is not worth my time to worry about it.
My simple description to new shooters - close the bolt and as the cartridge is picked up and enters the chamber, can you reverse direction and the cartridge be 'controlled' by the bolt (ie rim of case is now under the extractors) and thus CRF... or do you need to fully close and cycle the bolt handle BEFORE you can eject the rd (rim is NOT under extractors until the bolt is fully closed) and thus push feed.
About as basic a description I can make and all that anyone needs to know to separate CRF and Push feed. Not sure how you could have a partial CRF?
Now some will hear about how a CRF makes it 'impossible' to close the bolt if you have to single load/drop a cartridge into the chamber without using the mag. There might be one or two custom actions that have this issue.... for this game, you need to able to close that bolt no matter how the ammo is introduced to the chamber. All popular factory actions common to rimfire prs WILL close on a single fed rd.

As someone about to build a production gun and looking at the T1X as the leading option can you be more descriptive on the feed issue?
