Re: 7mm STW
Start at 77 grs and work up. I get vertical at less than 77 gr. My rifle has a Wyatt's extended magazine box so I set the cartridge length to 3.800", just short of the lands (I don't want the bullet touching the lands in a magazine rifle even if it does group a little better that way).
So far, 78.5 grs looks very promising, but further testing is forthcoming.
One shooter reports excellent result at 79 gr, but this may be too hot in some rifles.
