[Jim Hundley]

Please don't laugh,but what is the .300 Ackley Magnum made of:.300 Win.mag.,.300 Whby.?I know it is a blown out configuration of what mother cartridge?What velocities are obtainable with a 180gr. bullet?I don't have a reference book.Guess I had better get one to answer my own questions.
Thank you,Jimmy.

The 300Ackley is actualy a blown out 300H&H case but the 300Wby is just barleysmaller so guys use the 300Wby to make the 300AI cases , just alot less fuss in the fire forming process
I had one for a while and realy liked it , it was not a tight necked chamber but having the throat cut to fit the 175gr SMK bullet was nice accuracy was outstanding and case life was good. I'm not to sure that I'd do it again with all the new non belted mags out their but If I were looking for a good long range rig with not so much power as the RUM's then I'd get the 300Ai , my rig shot factory Wby ammo into the 1" range but after the case was formed and the load worked up it would shoot around 1/3MOA at 300yds. Their is realy not enough ballistic advantage over the Wby to make any strong claims but its differant.

I guess that I ment the .300AI.This must be the same round as the .30 Hart,.300 Borden Caribou,etc.Thanks for the info!
