Been shooting the DW445 for going on 10 years now. I have gone through 4 barrels and the frame is still tight. Unfortunately the starline brass does not allow you to develope the full potential of this cartridge.
My old IHMSA load and current hunting load (taken from the silhouette) is:
WW-680 (32Gr.)
240 Gr. Speer TMJ
Fed 200 Primers
Trim length 1.605"/1.607"
Here is the real interesting part: :shock:
Manufacture from 30-40 Krag brass. Face rim to .058" thickness & .535" Dia. Trim mouth if needed so that loaded O.D. is .452"
Prep Sequence: 1)Trim off below neck 2)Trim rim thickness & O.D. 3)Flare Mouth 4)Trim O.A.L 5)Fire form
Fire form load = 25.5 Gr. H4227, Speer 240 Gr., Fed 210, light to no crimp
Measurements: Cyl Base = .459", Case base = .459", Case mouth dia = .452"(30/40) & .448"(Gates)
As always, approach load carefully and reduce load at any sign of excess pressure.
