Do full sized stocks affect accuracy?

Lots of good info and comparisons over at Rimfire Central in the CZ/Brno forum. From what I've read there, the full stocks seem to be a bit more accurate.
 
Why isn't it fee floated? Just because the stock is all the way to the end of the barrel doesn't mean its tight together. I have a 455fs only because I had a heck of a time looking for a 452. Only shot 50 rounds form mine before I took it apart to refinish the stock on it. Its still apart lol
 
I may be wrong ( it happened once ) but I wouldn't be worried about accuracy as far as cz is concerned , they are a top quality gun manufacturer and every cz I've ever shot has been a tac driver . You can't go wrong buying a cz .
 
Isn't 455 FS free floated all the way?
I think there is a little bid of a Black Magic involved when it comes down to the "free floated" versus "not free floated" question. Some barrels shoot better if they are supported at the end (my old 10-22) and some not. My 452 FS in 22LR is my most accurate CZ out of the 4 that I have. I have no idea if it is the full contact between the stock and the barrel that makes it so accurate or if it is a combination of many factors (probably....). I bet all higher end target rifles are free floated.
 
I'd be surprised it if was. Maaaybe over time the wood will warp enough to affect aim, but in general CZ prides itself on accuracy. They wouldn't sell a MS stock if it was ruining their aim points.

I want one too, good luck with yours.
 
A full length stock can't be free-floated, at least not forever. The wood would be hanging there, unsupported, and would warp. All full-stock rifles at minimum will be anchored at the muzzle. In bigger calibers, the barrel will heat up and put pressure against the mounting point, adversely affecting accuracy. With a .22 LR, this shouldn't be much of an issue. The main issue is barrel harmonics, which are affected for sure due to the anchor point, but they can still shoot really well. If you were to take 10 rifles each of full stock and standard design side by side, the full stocks would not be as accurate overall, with some individual exceptions. Any time you interrupt the barrel's wave motion when fired will more often than not degrade accuracy, which is why free-floating is so popular and effective.
 
I made two 452 Varmint Mannlicher style rifles by 45ing the forend and extending with cocobolo... both of these were free floated... but most FS stocks are not free floated... there are varying opinions on free floating, some advocate an opposing force pressure pad to aid in repeatability... and also, because a stock is free floated when it is static in your hands does not mean that it does not come into contact with the stock during the firing cycle... there are a multitude of directional forces at work, not the least of which is your hold and or rest of the gun while firing... this comes into play more dramatically with centerfire as opposed to rimfire rifles... I currently have eight FS rifles, mostly centerfire... and while I am prepared to say that an FS is more bad than good with regard to accuracy... all of my rifles are satisfactorily accurate for their purpose and I love the look, feel and handling of the Mannlicher style stocks.
 
The 455 FS is definitely free floated, and is not anchored at the muzzle. I own one.
However, it's a very close fit, and I'm sure that over time the gap will diminish until it no longer floats.
I can take pictures of the barrel channel and/or fitment if anyone really needs them. (PM me though, since I don't come here much anymore)

As the others said, nobody has ever complained about the accuracy in either the non-floated 452 or floated 455, so you shouldn't worry about it.

...call me stupid (here's your chance) :p ...but in 40 years i never thought about the effect of free floating barrels on .22's...just assumed that high powered rifles set up much more a vibration than the lowly .22 so all my centre-fires are floated...enlighten me (don't mean to steal the thread)
