Re: 22-243 ackley Whats the powder to use
[ QUOTE ]
I just got a new PTG no turn match 22-243 ackley reamer set up for the 75 and 80 grain pills. The 22-243 seems to be almost identical in performane to a 22-250 ackley they both hold around 44 grains of rl 22 to the base of the neck. You can't compare a 6 br to a 22-243 ackley fast twist. You just cant. It's like a 308 and a 300 ultra they both have their place, but completely different animals. Let me how you gun shoots after the rechamber.

after reading this I had to check it out. I used win748 powder and filled both to the base of the neck (3 times just to make sure it was accurate) the 22-250AI holds 47.5gr and the 22-243 held 53.8gr. I'm sure there are different chamber and brass variations but the 22-243 has at least a 10% bigger powder cap.
David Tubb's 6XC cartridge is basicly a 22-250 Imp 30 degree shoulder necked up to 243, he claims it is 7grains smaller than a 243Win. just some added info to kick around.
It takes 43 muscle's to frown and 17 to smile, but only 3 for proper trigger pull.
