I never did buy a copy of Quick Load. Until now I have never asked for anyone to check something for me. I promise to save aluminum cans and scrap iron (sell off some take-off barrels even) to pay for a copy over the winter.

Here goes. Does Quick Load have anything on the 9.3 x 70 Expert Magnum (Expert is the company that makes brass in this size.).

The 9.3 x 70 is simply the 404 Jeffery left nearly full length and necked down to 9.3mm. Does Quick Load help with starting loads with the 286-grain bullets, or even the 320-grain Woodleigh protected point/solid?

I am guessing that H-1000 is on the fast end, Retumbo in the middle, the new RL-33 and Hodgdon's 869 or 50 BMG on the slow end. Yes, it is a trifle over bore, but not as bad as the .30-378 Weatherby or the 7mm RUM.Any help would be appreciated.

Tom in Cody has had a rifle made up for the 375 Ruger shortened to 2.5" and necked down to 9.3mm. He correctly calls it the 9.3 x 64 Newton.


that is a much more sensible cartridge, but I have always wanted a loader for my main gun, just like tanks have in the military.

QL list three 9.3x70 these are the two largest.

9.3x70 Mag(DWM569) 105 gr capacity
9.3x70 RWS Exp 88 gr capacity

Thank you Paul,

That is extremely helpful. This puppy may not be quite as overbore as I thought. I will put water in one of my pieces of EXP brass, and also measure it from a reformed 404 case.

Full speed ahead, for my friend, who bought the action, stock and some brass from me.
