Now I'll be the first to admit that as yet I've never loaded for .300Rum but... .It wasn't a typo but it was the wrong info. The stated info was for the 185's. The 210's are running a good bit slower at 3450 fps. I run the 210's at 3450 with 98 grns of H1000, the 185's at 3650 with 102 grns of H1000 and the 155's really sizzle at 3970 fps with 108 grns of H1000.
Not a rocket but it'll shoot!
According to the data I got from Berger after reading your post 84.4gr of H-1000=96% of case capacity.
How are you tamping in 20 plus more grains of powder and seating a bullet on top of it and not blowing it up?
I won't be moved into my new place and set up to reload again until probably late spring or I'd be trying to work this out for myself so I'll have to rely on your expertise and experience vs what Mr. Berger is telling me.
