P.O. Ackley and other WildCat Guru\'s Books?

I am interested in learning about improvements to cartridges made by P.O. Ackley and other Wildcat Guru types. Anybody know of any good books I can learn from? Is there a 300WM Ackley improved? I will be rebarreling and customizing my Sako 75 SS this winter. I would likely stick to 300WM so I can use Lapua brass but I just might go to a 300WM Ackley improved if there is such a thing.

Last time I looked, the Ackley books were reprinted and offered by Sinclair. This would be a good place to begin. However, since the developement of the "Improved" cartridge, many new powders and bullets have been offered and the load possibility is most mind boggling.

You should also be able to do some free research on your pc... Might not be everything you're looking for, but hey, it's FREE.

In P.O. Ackleys books he speeks of several "improved" 30 cal mags , I believe though that most if not all of them are based off of the 300 H&H mag. Their are dozens of them , I'm sure that one is very close to the 300 Win case , I know that Midway offers a reamer for the 300 Win improved. I'm not to certain how much you would gain performance wise by improving the 300 case as it is prettymuch overbored already , you may be ablle to get a little more velocity and maybe longer case life but I'm not to sure it would realy be worth the hassel.
What are you intending to use this gun for? and are you dead set on the 30 cal's ?
 
Re: P.O. Ackley and other WildCat Guru\'s Books?

I am dead set on 30 cal. I'm doing a rebarrel this winter and I am just tossing around the Idea of improving the 300WM cartridge. I could simply go to a 300RUM but I would not be able to use Lapua brass and I think I would be looking at a fair increase in recoil.

Did a Google search on Ackley and couldn't find a bio or any info on his idea's.

Here is some biographical material:

Forward

Handbook for Shooters & Reloaders Volume I & II
by P.O. Ackley
The author, P.O. Ackley, has been associated with the developement of high velocity "wildcat" cartridges for over a quarter of a century, and is one of the formost authorities on "wildcat" cartridges. He is also a well known rifle barrel maker and custom rifle builder.

P.O. Ackley is a native of Granville, New York. He graduated from Syracuse University, Magna cum laude, in 1927 and entered the full-time gunsmith business in Roseburg, Oregon in 1936. This enterprise flourished, but in 1942 war work beckoned and he became attached to the Ordnance Department and was with the small arms section in Ogden, Utah, until 1941.

He re-established his gunshop at Trinidad, Colorado in 1945 and had one of the largest custom gun shops in the nation. He was instructor in theory of gunmaking and metallurgy at Trinidad State Junior College in 1946 to 1951, and carried on extensive experimental work at the college and in his own shop which had been incorporated in 1947.

Mr. Ackley has been a regular contributor of magazine articles. He is a member of the Technical staff of "Guns & Ammo" and is the Gunsmithing Columnist of "Shooting Times". He has built a reputation for "always telling the truth" in his writings.

His line of "wildcat" cartridges represents superlative engineering and unfailing adherence to standards of uncompromising quality. They are, in fact, no longer true "wildcats", for they have been accepted by the shooting public and have proven themselves in game fields all over the world.

Ackley rifle barrels have been in constant demand over the years not only for experimental work but by other custom rifle makers who proudly advertise "Barrels by Ackley". Experimenters almost unfailingly call on P.O. Ackley for their exacting demands in rifled tubes, knowing that through them will be delivered the last potential of their ideas. Many of his barrels have been used in experiments which have resulted in the success of our missle program.

The author's opinion of the various "wildcat" cartridges is given in the description of each cartridge as it is found in this book. This opinion is based on many years of experience. However, this is personal opinion and should be considered as such.

Paul W. Cox, 1962

Mr Ackley died in 1989 at the age of 86.

NorthernSniper,

Here is the condensed version of the longer explanation that I had written before a freak storm took out the town's electricity.

Books:

P.O. Ackley's 2 book set is available from Brownells, Midway and E.A. Brown & Co. as well as the already mentioned Sinclair's.

Wildcat Cartridges Vol. I&II from Wolfe Publishing

The Handloaders Manual of Cartridge Conversions by Donnelly (there is a revised version available through Midway).

The Gunsmiths Book of Chamber Prints by Dave Kiff

This thought of 'improving' the 300 Win. Mag. is a little wasteful since the only thing that will change with any significance will be the shoulder angle and it will come at the high cost of a new reamer and more expensive dies. The gain will be very close to nil compared to the original cartridge. Besides, the 300 Win. Mag. has been very accurate and successful in its original form since it was introduced.

The one drawback to the 300 Win. Mag. is the short neck. But that can fixed by taking a look at the wildcat 30-338 Win. Mag. This is merely the .338 Win. Mag. necked down to accept the 30 cal. bullets. It is competition proven for accuracy and efficiency.

Some wildcats to consider:

30 BooBoo (8x68S necked down and improved by Dave Tooley)

30-416 Rigby (have to check bolt diameter for rim size)

300 Jarrett (8mm Rem. Mag. necked down by
Kenny Jarrett)

300 WBY Ackley/300 H&H Ackley

308 Baer (300 WBY/300 H&H, 8mm Rem., 340 WBY)

and about a dozen more that get shot at the 1000 yd. benchrest matches.

Just a couple of observations.

Because of the incredible improvements in barrels, bullets and mostly powders, these cartridges are not now considered overbore. With proper load development, these new powders burn very efficiently.

As much as we all admire the Lapua and Norma brass for consistancy, they are not the end-all of cartridge manufacturing. I wouldn't dream of abandoning a project just because brass wasn't made by either of them. There are a couple of high quality brass extruders in the U.S. that make a wide variety of cartridge brass at reasonable prices. Then there is RWS and Dieter Horneber in Germany. You can't just call them up and expect to get an order in a few days but if you plan ahead, the 6 to 8 week lead time will fly. The quality of their brass is at the very top of manufacturing. A selection of their brass is also available through Huntingtons.

Best.

Re: P.O. Ackley and other WildCat Guru\'s Books?

I have an awful lot of temptation toward the 30-338 but I think the recoil could be a little over the top for me. I am not a brake fan I have had trouble with them affecting accuracy before on a 308 WarBird the brake got erodded and I eventualy ended up with 8" groups.

NS,

I'm afraid that you confused me with this statement:

"I have an awful lot of temptation toward the 30-338 but I think the recoil could be a little over the top for me."

The 30-338 Win. Mag. has less capacity than the 300 Win. Mag., 86 gr. to 94 gr. How do you figure that the 30-338 will have more recoil? You've already shot the Warbird with a capacity of roughly 121 gr. of capacity. The 30-338 should be a piece of cake after that...

You don't need a brake with the 30-338 unless you want one. A lot of folks here use brakes on rifles and can account for stellar accuracy. Check the archives for target photos. "WyoWhisper/Ric Horst", Darryl Cassel and Boyd Heaton come mind quickly.

I've used brakes on rifles from .22 up through the .510 with no loss of accuracy. The only difference that I've found with brakes is when you take them off and shoot, the POI shifts so I have to re-tune or make a blank that imparts the same tune as the brake. That's what Wichester did with the BOSS system.

Best.
 
Re: P.O. Ackley and other WildCat Guru\'s Books?

Sounds to me like you talked yourself into the 30-338 winchester or the 308 norma mag (pretty much the same thing, you experienced gentlemen correct me if I'm wrong). Recoil will be less than the 300WM (though not enough to notice I'm sure). Many people have high regards for the 30-338 and 308 norma, and you have norma brass at your disposal. I'd give it a close look. I personally like the 300 dakota case configuration since it is beltless and has a longer neck than the 300WM. Do any of you know who produces the dakota cases for dakota, and have many people used this round for 1000 br? I see Dakota cases are $140 per 100 pieces.

Whoops! my mistake, I was thinking 30-338 Lapua Mag. I have read a lot so Many good things about the 30-338 Lapua lately I have 30-338 Lapua on the brain!
