No Sir! My 225 TSX load was about 2850 FPS, and that was with 70 grains of PP 2000-MR. I never shot 220's in my rifle. The 2975 FPS was the velocity I got with the 200 TTSX in a 23" 35 Whelen AI with Varmint. Looks like MedRiver got 2950 FPS with the 200 TTSX and Varmint in his 20" barrel. I had calculated 67 grains as max for the 200 grain bullet with Varmint in the basic Whelen - I ended up needing 68/Varmint in the Ackely to get that 2975 FPS with the 200 TTSX (I had calculated around 3000 FPS in a 24" barrel so that was close enough for me). Anxious to hear what the "book" charge was that gave MedRiver 2950 in his rifle.
Hope that clears it up. Those two powders do some wonderful things in the Whelen, but 2975 FPS with a 220 bullet would be (IMO) way over the top.
