I have had two Mod 700 Classics, had both reamed to the AI. I only killed game with 3 bullets; the 250X, the 200X and the 310 Woodleigh. I used the Speer 220fn for my fireforming loads but they were super accurate. IMO, the 200TTSX will give you the best "all around" load. It will definityly penetrate and yet not tear up a bunch of meat. the 310 was a wonderful bullet too, but I only killed 200# Eurasian that was close enough to brain-pan with my .38 +P, ha. Its a grand rifle/cartridge combo. Try a magnum primer with R15 and the 250 partition sometimes!
That's also what I'm reading is that RL15 is the ticket for the whelen.
