This cartridge is explained in great detail in Precision Shooting
magazine Feb. 99, Basically it is blown out and improved 22 BR, case capacity
is said to be 40.5 grains of water as compared to 22-250 at 45.0 grains
of water and the 6br at 36.5 grains of water..this cartridge is purported
to exceed
the 22-250 in velocity 50 grain nosler BT at 4040 fps...this in a 27" bbl |
 |
This Cartridge once ruled the benchrest line and is still a
fine choice for varminting in areas where a quieter round is desired |
 |
Why a 222 ackly??..Why not..?..it's not any more silly
that a 223 ackly (hehe) and may fill the age old mystical role of a cartridge that makes MORE velocity with LESS powder than larger rounds do..as well as reducing case stretch and bolt thrust to a minimum |
 |
Here is 22-250 right next to 22-250AI...I did not draw the extractor grooves because it is much easier not to, so do not think the whole cartridge is not there or some such...the important (to us) details are there. |
 |
This is a 22-250 with shoulder angle unchanged but body taper reduced
to .01 per side...this would be an interesting experiment because if one
was very carefull a factory rifle could be re-chambered without setting
the barrel back.
