Not sure with the .338 but my 300 WM is getting 3013 fps with 180 gr bullets, .012 off the lands and 78.5 gr of H1000. 2969 fps with 78 gr. I never tried 200 gr yet.
Nice stuff ..
Lot's are aging and can't handle recoil ... so , they have many stories of little wiennies (hot dogs ) shooting big stuff ..
Does a .277 cal to a .308 make a diff or even better yet
.264 to .308 ??
just asking , with the same bullet
