I agree about every bbl being unique.
I doubt it would be anywhere near 150 fps. total tho.
See "Fastest 338 without Cheytac" thread, Last pg. Post #29 by Kirby Allen (fiftydriver) in this section, page 3.
Im guessing somewhere in the 20-40 fps per inch with the RUM. I could be WAAAAAY off here, but if I'm interpreting Kirbys results correctly, I'd say you'll gain some for sure, but not any massive amount. Maybe I'm underestimating a bit, maybe not, but I'd rather figure low, & be pleasantly suprised with any extra.
I used to go with the 50-60 fps per inch theory, but looking at the link, & the post Kirby wrote, I don't know that it even aplies at all anymore.
