6mm Ackley
My grandfather said he purchased this gun from Ackley (?). Don't know whether to believe that or not. He has since passed away and I have been the proud receipient of the 6mm. It is in excellent condition. Not been handled often. Assume it's probably about 50 years old. There are a couple of fire formed Remington .236 brass along with it. My problem is this: I know nothing of the Ackley. Where does one go to begin a search. Gun smith? Here or where? Any info one might offer this dummy will be greatly appreciated. TIA

".236 Remington"? Huh. That sounds like commercial 6mm Lee Navy brass, which makes the brass alone about 75 years old.
What does the rifle look like? Is it maybe a Remington-Lee? Do you have pics? |

There is a book called "Wildcat Cartridges" available though Krause Publishing that can answer a lot of questions about different cartridges. Ackley became well-known for "improving" cartridges (expanding case capacity by straightening case taper and steeper case shoulder angle).
Keep in mind that it may also be a standard factory round. "6mm" before 1964 typically meant 6mm Lee Navy, since there were very few other 6mm cartridges to be found anywhere, much like "7mm" used to refer to 7X57 but now is typically used to refer to 7mm Remington Magnum. There is a 6mm Ackley based on an improved 6mm Lee Navy, but PO Ackley was prone to attaching very similar names to very different cartridges (22 Ackley Magnum, 228 Ackley Magnum; 25 Ackley, 25 Ackley Krag; etc). The 236 Remington brass is a dead giveaway. There are other wildcats around using 220 Swift brass necked up to 6mm. Since they use the Swift semi-rimmed case, they are strictly speaking not 6mm Lee Navy Improved. Like many gunsmiths, PO Ackley did many rebarreling jobs, and many customers did not want wildcat chambers. PO Ackley always stamped his name right by the chambering stamp, and a lot of people over the years have assumed that because his name was on a rifle barrel, that it must be chambered for an improved cartridge, when in fact the rifle may have been chambered for just a standard factory chambering.

Parker O. Ackley was a Colorado gunsmith & author, among other things - who did LOTS of custom work during the early-1950's through the mid-1970's.
He - or his shop, rather - rebored a .243 Winchester Model 100 semi-auto to .358" for me in 1971 that worked very well. IIRC, he was either THE founder, or one of the major factors in establishing the Trinity School of Gunsmithing. I would wager that your 6mm Ackley is a blown-out wildcat based on the 6mm Remington commercial round - which was originally a direct competitor to the .243 Winchester that was introduced after the .308 (1955). The 6mm Remington uses/used the same basic brass as the 7x57 Mauser, IIRC - and was chambered in many other commercial rifles. . Last edited by PetahW; December 23, 2009 at 07:15 PM. |

There are separate listings in some of the cartridge collector and custom ammo sites for .236 Remingon Lee and 6mm/236 Lee Navy. But they did that a lot in those days.
It is going to take some pictures of the actual gun and brass. |

Thanks to all for your kind replies. Now comes the new ground. I have reloaded pistol ammo for quite some time, but this rifle stuff is new ground for me. Since my original post, I have spent many many hours surfing the net to read all that I could digest about the 6mm AI. Decided upon the following for my choice of ammo: Fireformed Remington 6mm, 50gr IMR-4831, 87gn Hornady VMAX and CCI-BR primers (?). However I am confused by the different CCI primers mentioned in many posts on the net. What am I looking to purchase, a CCI-200 Large Rifle primer, a CCI-BR or a CCI-BR2?

I would use CCI 200's, as the other are for specialty benchrest/target cartridges, AFAIK.
