Need Help loading 30-06 in 1903 Springfield

Thanks Kraschenbrin,

All things being equal I will probably continue to buy from the man who supports this sight. He is a Scouter too, as am I. We should all patronize good people when we can.

I had good results loading 311299 in my 1903 Mark 1 Springfield. Bullet sized .313, 34 Grains of Win 748, seated to cover top lube groove. Use Lyman Alox lube.

Same load works in 308 Winchester, 303 British, 7.65 Argentine and 7.7 Arisaka.

Have also used 12 grains of Unique for a lighter load.

I bought this mold in 1962 to loads for an 1981 Argentine Mauser and a SMLE No.1 MkIII*.

I'm not a fan of W748 for loads under 35K PSI. Too many pressure excursions and variations in velocity, and very position sensitive. I'm not against using W748 with cast. I'm speaking from the viewpoint of having bought an 8 lb keg years ago, and trying to use it for just about everything. I just find it less flexible than other powders. Where it works, it works well, which is in high density, full pressure, full performance applications.

Felix pointed out in a post here years ago that it has a heavy retardation coating and specifically didn't recommend it for light loads for that reasons. Most any medium rate ball powder does better in reduced loads, extruded better still. Let me dig that up...

Not sure what Lyman moulds you're using but you might slip over to NOE (shouldn't be too far from you) and check out the 30 XCB mould (310-165-FN). Here's 2 sighters and 10 for "record" I shot last week or so with my M1903A1 NM Type II. My XCBs are cast of #2 alloy, WQ'd out of the mould, weight sorted for match select bullets, GC'd with Hornady's and lubed with White Label 2500+. I loaded them in LC67 Match cases with a WLR primer over 18 gr Alliant 2400 with a Dacron filler.
