Thank you for your answer but I'm not sure what it means. If the V-22 chamber shoots all higher quality match ammo what makes it a Lapua chamber.
As noted by littlesister, Lapua has a rather thick rim compared to other higher quality match .22 rimfire rounds. Current production averaging (1000 round) is about .041 for Lapua. About .039 for Eley.
Since rim thickness dictates chamber depth for headspacing, but has nothing to do with the shape of the chamber or the leade angle. I guess they are referring to the chamber depth rather than the chambers design.
Here is a list of common .22 rimfire chambers.

I read something somewhere that says Vudoo chambers are cut like the Winchester 52 chamber. However, I cannot remember where I read that.
When I looked at the chart that you provided and compared that to Vudoo's statement about the bullet just touching the lands, that makes sense.
I could care less what they call the chambering; "Match, Super-Match, Lapua, W-52 Match" or "hand crafted by secret gunsmithing elves." I just want the darn thing to give me tight groups with what I feed it.
I have oodles of Norma Match (RWS) that I shoot in my Anschutz with outstanding results. So, rather than buying Lapua, I'm going to experiment with what I have on hand.
I've always felt that the less jump that a bullet has the more accurate the round will be. That isn't always the case but seems to be the norm. The reason most rimfire chambers have a longer jump is because the variety of ammunition.
The reason that Mr. Bush cuts his chambers short is probably because he expects his customers to be as discriminating with their ammunition as their rifle purchase. And YES, I WILL try CCI SV, just to see what it will do
I like the controlled feed aspect of the rifle's action. Not having the bullet touch anything before it enters the chamber has to be a plus.
I'm going out on a limb here. So someone correct me if I'm wrong. I would guess that Vudoo cut their chambers based on experience with the WW-52 or possibly the 40X but decided to use Lapua ammunition as their testing fodder.
Because they used Lapua as their go-to ammunition for testing, the rumor got around that they cut their chambers for Lapua.
