Tried out the M210 Nitro Mega-weight load this weekend......BPS 10 w/26" w/.690 Indrian Creek, lengthened forcing cone, ported & polished barrel, could only get 32 yard shots (busy weekend shooting range), however i am pleased at the 362 hole count in that 10" circle with that new 4x5x6x7 Mega-weight shell. I kept blowing the pallet w/stapled target paper backwards and over with every shot. I have shot the .710 Indian Creek with Nitro's H210 5x6x7 load with not near the results as this .690 w/ 4x5x6x7 loads. Nitro recommended the .690 and I couldn't be happier.
The Indian Creek 690 will be the first choke screwed in to mind when I get it. It shoots the Mag Blends well I hear also. So that is Nitros and Mag Blends out of one choke!
