Ya' - It could still work good if you throw a hotter flame at it. Depending on what primers you are using, you may tighten up the group by trying a magnum primer like a GM215M or a match primer in general (210M).
I am not sure how much time you have spent with the X bullet (please do not be insulted - your a Killer), but sometimes if you seat the bullet a little deeper, the group will tighten up and the pressure will drop - just the opposite of regular lead core bullets. The only exception to that (in my experience) has been with the XLC. That particular X bullet was much more tolerant regarding seating the pill closer to the lands. The XLC was incredibly accurate at higher velocities and it shot very well in a dirty barrel (I wish they would not have discontinued it). I had no trouble getting 3100+ fps out of my 26" J.P. Sauer .338 with the 210 XLC's while still experiencing consistent sub 3/4" groups. It would poke two holes through an elk at any angle. When you squeezed off - both you and the elk were very aware!
Anyway...I have had allot of luck in my 22" pencil using Win760 and 210M's in .270. But I would not hesitate to continue to play with 4831.
I will find the 130X data tomorrow buy I am sure it was 760 that made me smile. ;D
These are my express opinions derived from my experiences - I know less than most and half as much as some!
Kids - Don't try this at home...
