Gentlemen,again,thanks for your input.
Norhman,I have never found any printed load data for the .224 Vais,I had to go right to the source and that was Ron at Vais muzzle brakes.I eventually found someone who is very up on the Vais and shoots it allot,mostly with 80 grain SMK.He also shoots a 6mm Vais and likes it allot,can't recall what velocity's he was getting with it,it's been awhile since I've talked to him.He is someone other than 3700 fps guy.I have connected with maybe 3-4 guys who load for it.Gary
Not sure, I have tested the 100 gr ULD RBBT in a 30" barreled 22-6mm AI and got around 3150 fps. Topped 3200 fps but case life would be quite limited.
My 224 AM has hit 3425 fps with tight primer pockets but had other issues with case design, so not sure if this is an accurate representation of what the round will really do. Pressure wise it was fine.
I am not sure where the 224 Vias lands compared to these two in capacity. My AM holds up to 73.0 gr WC872 so you can use that as a comparision on the Vias. I suspect the 22-6mm AI is very similiar to the Vias in capacity but not sure.

Millerlite, There is an article (King of the Deuces) on the .224 Vais in the April 1998 edition of Precision Shooting, by L D Standish. I have selected several quotes from that article:
"To be dubbed the .224 Vais (what else?), the new cartridge was to be a necked-down, blown-out 6.5 x 55 Swedish Mauser with a 35 degree shoulder, for which there is a plentiful supply of brass. "
"What if I told you I have a .22 that makes a .220 Swift look like a defective mortar, and leaves a .224 Clark standing in the dust?
"What if I told you it would even equal or better the 6-.284's statistics, and the brass is available from all the major suppliers, including Norma, Lapua, Winchester, RWS, and Remington? "
The test was with the JLK 80 grain VLD and using RE22, but no loads were mentioned, but this quote caught my attention:
"With the barrel broken in and load testing and tuning complete, the .224 Vais is consistently turning in groups mostly averaging in the low to mid 2's at a measured average velocity of 3,773 fps (10 feet from the muzzle). "
There are a lot of statements in the article that are open to challenge, and I note that in the .224 Vais he is getting 3,773 fps with the 80 grain JLK in a 30 inch barrel, while in the .224 Clark, I got about 3730 fps with the 80 grain Sierra MK in a 25.25 inch barrel. Yet he claims the .224 Vais leaves the "Clark" in its dust.
As both the 224 Clark and 22/6mmAI, have the 7x57mm mauser case as the parent, you would expect them to have a marginally larger case capacity than the 224 Vais which is based on the 6.5x55mm Swedish case.
I also agree with Kirby regarding trying to exceed about 3,500 fps with the 75 Amax. I can recall many reports that they have come apart at velocities between 3,600 and 3,800, and especially when using a 1 in 8 twist. A velocity of 3,500 - 3,600 fps can easily be achieved by using the smaller capacity 22/6mm (unimproved)case.
Personally if I was using a case with the capacity of the .224 Vais, I would concentrate on using bullets in the 80 - 100 grain range, but this would require using a 1 in 7 twist barrel. Hope that the above helps. Brian.
Brian,that same article is on the Vais Arms website.I'm with you, being suspect on those velocities.I'm going to set up my switch barrel as a .224 Vais with a 8 twist for the 75 and 80 grainers.If it'll consistantly whack Chucks in the 400-500 yard range ,I'd be happy at whatever velocity it did.However,I can attest, that my Vais with 50 grain NBT's is doing 4350 fps and will squeeze a bit more if I really pushed it.Won't have the 8 twist set up for Chucks this season,but am planning to use as is.Hell,maybe I'll find with that velocity and trajectory ,I would'nt need anything else,we shall see.I've only used it on Coyotes so far.Gary
