.30-06 case capacity Winny vs LC

[GhostFace]

I have some LC on the way to me as I could not find anymore Winny brass. I developed my load with Winny brass and I was wondering if could simply drop the charge by 1.0 grain. I know in comparing .308 brass between the two makes LC seems to have 1.0 grain less capacity, I did not if this held true for '06 brass too. Does anyone know? Thanks....

I use m72 brass, it is extremely heavy at 190gr. Commercial brass I've weighed has been 160-175gr.

308 brass is at least a grain difference, 30-06 is at least the same.

Okay, thanks guys. I will start by reducing my charge by 1.0 grain and see what happens.

I have found little difference between LC(67-68) and modern Lapua. So little in fact I use the same charge in both. My load is pretty mild for my barrel so YMMV. Unless you are running the ragged edge of being too hot I would think dropping a full grain would be OK.
