What are the reasons that the 300 Ackley dominates among the 30s in 1000 yard competition?
300 Ackley in competition
- Thread starter longshooter
- Start date
.300 Ackleys aren't used at all in long range prone rifle matches. This is because the cartridge generates too much recoil for 20+ shot strings of fire - and you're forbidden from using muzzle brakes because they kick up dust into the faces of shooters on adjacent firing points.
,As an aside, there are far more prone LR matches than there are LR benchrest events.)

the 300 ackley is a 300 weatherby mag improved. alot of the shooter at 1000 yard benchrest use them, check out hawksridge.com for more info
The 300 Ackley Magnum is actually the 300 H&H case improved. Many shooters will start with the Weatherby brass because it is higher quality. There are several versions of the Ackley but the differences are minor until you get into the few, like the 300 Hart, that actually do increase the capacity.
There is also a 300 WBY Improved which is sort of a misnomer because it's almost impossible to improve that case except to eliminate the rounded corners.
To say that the cartridge "dominates" at 1000 yard Benchrest is certainly dependant on your definition of "dominates."

Yes sirs,
Sorry for the lack of response, have been away from home.
The question was posed after reading the nov 7 daily bulletin article about steve shelp's statistics concerning 1k benchrest winners over the course of several years. It is indicated that the 30 mags dominate the field, with the 300 AI on the top of the heap. Perhaps it is the shear number of rifles used in competition, or perhaps there are other reasons that the 300 AI does so well.
I am interested in knowing those reasons.
Thank you,

Thank you much fellas, for the replies.
My 300 AI is a 300 Winchester magnum modification. Its basically a 300 win mag with a 40 degree shoulder. And it handles 220 smks and 240s quite well.

Ackley's manual states "Loading data is same as for .300 Weatherby". Got a 30 degree model and all I can say is in a 26" sporter barreled Remington 721 it kicks like a Mule! Unscrewed the barrel and put it on a shelf! 
Cheechako is correct. The .300 Ackley is a .300 H&H Improved. The H20 Capacity of the .300 H&H is around 85.3 gr., .300 WBY is around 97.2 gr. and the .300 Ackley is around 102.9 gr. using Norma .300 WBY brass. The .300 AI will run the 210 Class pills between 3,050 – 3,150 fps. Dave Kiff will tell you that he has a plethora of different .300 Ackley Prints to choose from. A lot of which are the same animal with a different name. Some have Free Bore built in and some do not. I shoot a .300 ATLAS which is the same animal. The reamer that mine was modeled after has won a truck load of wood from Hawks Ridge. It has a Body Taper of .00753†TPI and a Neck Taper of .00296†TPI, with the addition of a .156†FB. The trick with the Ackley is in the Headspace Gauge.

For info, there's a nice article about the .300H&H AI on p22 of the May 2012 Rifle magazine by John Haviland

Recoil is a bit much I don't like the 300AI for that reason I would rather shoot a 300WSM and use 60-65 grains of powder and shoot a 190 @ 3050fps. For 1000 yards that is PLENTY if you wanna go further than that I would skip the 300AI and go to the 300RUM I have a friend pushing 230 hybrids @ 3100 with that but the recoil is more than I am gonna shoot or at least shoot well.
