Hello,

What is your prefered common powder you use for both .338 Lapua Mag and .308 Winchester ?

If it matters, I will also be trying to produce a common .308 load for Remington PSS bolt, Seekins SP10 AR10, and Springfield Super Nat. Match M1A guns.
I don't know how doable this last part will be...

Are you just looking for it to go bang or want some precision?

I'd bet any powder you want to use in the 338 will be way too slow for the 308.

I am a newbie, so, trying to get by with as little I can to start with.
I am understanding there isn't a common ground between the two.

Still schooling...

You'll be hard pressed to find a common powder between those two cartridges... pretty much opposite ends of the spectrum.

I've had great luck with Varget and IMR4166 in the .308. Big cased 33s really seem to like RL33 and H4831SC
