Looking 338 JDJ Quickload guidelines.

[Prologix]

Specially looking for a starting load and a peak velocity using Barnes 160gr ttsx and W-748 powder. Primers are Fed GM large rifle. Brass is resized 375 JDJ. What other info would you need?
Other possible powder would be Varget if there is an issue using W-748.

Sorry I forgot to mention 15 inch barrel with about 2 inches muzzle break.

I've had a .338 JDJ since it's inception. JD is a good friend & got a great load sheet from him. PM me with your name & address & I'll mail it to you. I only used AA2520, but the load sheet has other powder choices. WW 748 is not listed. Lot of Varget loads.
He frowns on solid copper bullets in Contenders, but I used a few sparingly. Better results with Horn. & Nos. PTs.

Not knowing what your average measured case volume is for fired unsizsed brass or what kind of velocity your lot of that powder tends to produce, this chart might give you some ideas. Note the COAL being used. Always start low and work up with your charges with particular gun as the pressure/velocity from QuickLoad is never right on until it is tuned to your lot of powder.
