In reading all the stories about Eleanor O'Connor and her 7x57, I keep coming up with the 'pet' load that Jack put together for her, using a Hornady 165gr bullet pushed to I believe 2660fps. My question is what the heck did he use to acheive this?? I just can't find a powder that will do this, given the case size and what it will hold - run out of room to stuff anymore in.
Anyone have any info or pet loads they would care to share? Have several 7x57 to work with, latest being a Mod 77 Ruger that I am anxious to get out and on paper.
Thanks for the response,

Any of these should put you close, 760,h-4831,h414.

These might help. BTW hornady no longer makes a 165, they do make a 154, 162, 175.

Well, now you have my feeble brain trying to remember, but I thought Eleanor O'Connor shot most of her stuff with a 7 X 57 using Sierra 160 grain bullets.

I will have to get out some of my O'Connor books, but it seems to me that she shot a 160 Sierra at about 2650 fps. The load he used was with H 4831 powder, but I do not remember how much.

I cannot remember Hornady ever making 165 grain 7mm bullets.

He used to brag about the 139 Federal loads. I have all but two of his books so I'll try to find an answer.

You have to remember, when looking at any loads O'Connor developed using H 4831, that he was using the old surplus H 4831, which was slower-burning than today's H 4831. That old surplus stuff is no longer available, except to those fortunate shooters who laid in a stash of it and still have some left. (Lucky bastards!)

So if you use O'Connor's data with present-day H 4831 you will likely get a load that is dangerously over-pressure.

Ackleys Handbook (Vol 1) shows 47gr 4350 and 160's @ 2665 fps, and 49gr 4350 @2750 fps. Sierra's MAX (Again MAX!) load for the same is 45.7gr @2600. BIG difference in load data, I'd be carefull if I were you. Ackley's data was published in 1962. Sierra data is from their 50th anniversary edition.

I still have several pounds of the 60s milsurp 4831 (that i purchased in the 60s). Kept in a Coleman fuel can it will open easily in case of some accidental application of an external heat source. I think it proabably protects the contents much better than modern plastic jugs also!
We went together and bought a barrel of the stuff.

Came out to the ridiculous price of 50 cents a pound I believe.

I was unhappy at the time that it would NOT burn with heavy bullets in my 219 Donaldson Wasp.

Trapper,

Eleanor's load is given in the 1974 Gun Digest in an article by Jack entitled Forty Years with the Little 7mm . She used "various 160-gr. bullets pushed by 52 grains of 4831. Velocity in the 22-inch barrel of her rifle is 2,660." As mentioned previously this was surplus 4831, not the currently manufactured H4831 or IMR4831.
