Anyone shoot a 257 Roberts Ackley?

[Michael O'Connor]

I shoot 25acp, 25-20, 250 Sav, 257 Roberts, 257 Roberts Ackley, 257 Roberts Ackley rimmed, and 25-06.

The first 1" group I ever got was with my 257 Roberts Ackley in 2002. It gave me a 1/2" 5 shot group a week later.

I can remember that at 3900 fps 75 gr Vmax, the brass was good for one firing, and primer pocket was loose. I hated fire forming more brass.

What would get me back into 257RAI is if Nosler sold the brass. They sell 280AI, and it great stuff.

Doing case research in RWS and Lapua brass options.

I have only had one, my very first "Improved" round. In 1982, Vidor Texas ( Klan country!) I was a mud engineer on a drilling rig jobsite and visited a small gunshop there. It was the first time I saw the Mod 700 Classic/Roberts in person, ha. Before it was over, I had traded a beautiful 6" colt Python ( super loud, abrasive grips and too pretty to put in a holster! ha) for that new Mod 700 Classic in .257 Roberts (24" barrel too!). I used it one season with the Speer 100 bt, but killed nothing. I then took it to a reputable gunsmith in Houston and he set the barrel back, cut the chamber with a crush fit for the 257 Roberts Ackley Improved ( I still like writing that!) I used factory 117RN to fireform. That Mod 700 had a LA and a long throat. so I set the Hornady 120HP way out, which meant I could use more powder! ha I was able to use PO Ackley's recipes from his Wildcat book! wow! I think it was 47-49 gr IMR 4350/120HP. I never had any of the "primer flattening/heavy bolt lift,etc" pressure signs nor ever clocked it. I only shot crows with it that summer ( it made the feathers & yellow guts fly!) and had to sell it! Its a shame to be young/struggling financially with twin girl babies and being a rifle Looney at the same time! ha) My friend used it on those East Texas deer and hogs like crazy. I ended up with that rifle, 25 yrs later, and he had cut that 24" barrel down to 21" to use in box blinds, and had shot the throat out. I just had a factory takeoff 25-06 barrel put on it, used it awhile. I still "like the looks" of Ackley cases, have had many calibers through the years Improved. However, QL specs revealed that my favorite loads were all running ( guesstimates you understand) at 70-72K pressure wise! While I never had one give me any problems, I am down to just one good eye ( my shooting eye) so now I don't have any. I do, however, think the 257 AI is the cutest, most useful of all his designs. Have a ball man!
