You are indeed a glutton for punishment! Your .450 Ackley is BRUTAL!

I can see the ad on Gunbroker......"once shot, and once dropped .585.............."
LOL! No thanks, I'll watch from the sidelines on this one! ;D

Frank Wells of Tuscon built a few of them he always threatened to send me one to try out but it never happened. According to Frank the recoil was beyond brutal and he specialized in large caliber rifles.
The heaviest recoiling rifle I ever hunted with was a 500 A Square stocked and worked over by Frank Wells. I used a .510 707 grain Barnes solid.
I would suggest a rifle weight of about 12lbs and consider the butt installed mercury recoil reducer as well as a muzzle break. If stocked in wood strait grain with a 2nd barrel mounted recoil lug. You probably already know this but the solid rubbers Silvers recoil pad is the best as while its soft there is not too much give as some of the pads will compress too quickly and increase felt recoil.
You will be impressed with the penetration from the momentum of the heavy bullets at reasonable velocities.
Good luck.

Len, Lee's .450 Ackley weighs 7-lbs and when you are chucking 500 grain bullets at nearly 2,400 fps, it's a bit lively to say the least. That thing made my Lott seem tame off the bench!
I agree, at least 12-lbs, but maybe 14.......

All good advice Len. The plan is for a 12 - 13 pound rifle and I may go with a mercury reducer. Doubt I'll use a full brake, but porting is an option I'll consider. I'd like to work up to top-end (750s @ 2,500 fps) to say I shot them. That being said, 750 grain Woodleighs around 2,000 fps should be plenty. I'll keep you all posted. -Lee www.singleactions.com |

I know what you mean I have shot some Ackley's in light guns and they come back fast and hard!
Cannot imagine the pain of a 750 grainer at 2500 fps
I am getting too old for this much fun.
Lee I do agree 750 grains at 2000 will penetrate anything you can hunt I think my 707grainers were around 2,000 and they have gone stem to stern on jumbos.

Aww Lee, I think you should just say the hell with it and build a 700 N.E.
That was a right impressive video too.

I've not worked with the 585 (24ga) However I have done some shooting of the .73 (12ga) with non-standard loadings.
About the most lively thing I've shot was a 2 ounce (880 grain) "maxi ball" at 1500 in a 7 1/2 pound fully rifled Savage 210 with plastic stock and 10 ply rated recoil pad. Calclulated recoil was a bit over 100 lbs and recoil velocity was somewhere around 32 fps.
I've shot some 1043 grain slugs at 1080fps and they were quite manageable.
I would imagine a 750 at 2150 in a well designed stock with a bit of mass will be easier to shoot than the plastic stocked savage. You will have far more bore capacity and less powder than a 50 bmg, so I'd bet you will have far less muzzle pressure. Therfore porting or a break may not be necessary. I personally detest muzzle breaks and porting.

This cartridge was first done by Gil Van Horn, I have seen a video of him and others test firing it. Ross was not aware of Gills design when Ross built his

Change of plans. Now I'm leaning towards a 600 Overkill:  I followed the devlopment of the round closely on the Accurate Reloading Forum years ago. 900 grain bullets @ 2,400 fps is downright jaw dropping (and maybe jaw breaking). -Lee www.singleactions.com |

Yep...brass is available thru Jamison International ($95 per 20; the Nyati is like $130 for 20 when it's available). CH also has the dies for $189 and at that price it isn't worth making my own. -Lee www.singleactions.com |
