I suspect that the olympic shooters, regular and biathalon who have their nation's pride and $$$ behind them are studying 22 rf ammo in ways far beyond our more amateur efforts.

The various 22 rf  50 yard benchrest guys have practically made a religion of it and the BenchrestCentral  22 rf  group pursues it in all of its arcane-ity. 

    The big difference between what we do and what they do is that we are chasing bulls-eyes at 100 and 200 yards. Those distances in the open air just add so many more factors that they simply don't know how to deal with it.  (Just out of curiosity, what is the max distance shot with the 22 in the Olympics now?)

However everything I have read seems to indicate that uniform case dimensions and consistently uniform distribution of the primer compound in the case rim are the "holy grail" of high grade match rimfire ammo.   Without consistent ignition everything else, bullets, lubes, powders, are all wasted.

I wonder if the priming mix could be done away with altogether?  and have some sort of electronic igniter?

Not legal in any shooting discipline that I know of.

If you go back re-read all of the posts it has been made perfectly clear that breach seating as far as ASSRA is concerned meets the rules and is totally acceptable. Therefore a change in the rules and or verbiage would not have to be entertained.

John Merz's match is not an ASSRA sponsored Match and breach seating is not allowed in the format that he has lined out. There is nothing wrong with that either, it is his match to be played by his rules and we should thank him for dearly for offering it to the Schuetzen shooting community. A match of that magnitude is not an easy endeavor so please support his efforts wholeheartedly without complaint and for those who will be participating I wish you the very best.

If you go by the below definition from Wikipedia Set_trigger has a point.

Cartridge (firearms)
A cartridge, also called a round, packages the bullet, propellant (usually either smokeless powder or gunpowder) and primer into a single unit within a containing metallic case that is precisely made to fit within the firing chamber of a firearm.

ST,
We can dissect this sentense farther,

Only .22 Short, Long or Long rifle cartridges shall be in this category.

I read it as saying that the rifle used needs capable of shooting only these type cartridges and so, be chambered for them, as it says "category". It does not say that only .22 short, long or long rifle cartridges must be shot in this class.

I don't think that if the traditional class said that "only original BP cartridges shall be in this category" that people would question if BSing would be allowed.

Also, in CF, being allowed to BS doesn't preclude being able to shoot fixed ammo.

If you look at Section 2.0 Ammunition. There is NO distinction between RF or CF. It says ONLY the word ammunition, and that can only mean ALL ammunition used in all ASSRA's matches, unless changed.

Section 2.03      Fixed Ammunition
Fixed ammunition may be used at the shooter’s option, or when required for certain matches, providing the components are in accord with the rules in Sections 2.01 and 2.02.

It says certain matches and not .22 rimfire matches. This is another reason to believe that the "cartridges" stated in the RF rule means "chambering".

JMO,

PS
If Lupua came out with a Platium grade of ammo and charged $1 per round, would anyone squack?

Yes, Joe but, it doesn't say they have to be "shot" only that they are in a "category". If 22rf's are a ammunition, they are covered in the ammuition section.

Frank

I sure do and there is nothing in the rule that states at it has to be shot that way. Only that they are in a category by themselves.

I again defer you to the ammunition rule. Unless you don't consider 22rf catridges ammunition.

Frank

Time to get back to the original subject at hand instead of trying to kill it with more nonesense that being the means and methods for breach seating rimfire for those who want to pursue it's use.
