Milk, I'm w/Don as to accuracy, you must remember that the bullet is landing w/in 1/2" of where the crosshair lies. I have only used the 115 TSX in my 25/06 and it killed 2 WT last fall, 1 shot each, one went 50 yds the other double lunged about 300yds but a good blood trail all the way, farthest I ever saw one go so you never know. I have used the original 100 gr. X's in the past for antelope, WT and coyotes and prefer the lighter weight as the faster you push an X the better they work, and don't let anybody convince you that they don't expand as I watched my buddy shoot an antelope doe (7 rem mag 140 orig X) at about 550 yds (paced it both ways) in the brisket top of heart and found it in the right ham fully expanded, it couldn't have been going much over 1900 fps. I know it was a dumb luck shot but 4 of us saw it. He got down w/bipod and said where do I aim?, I said an antelope high and sure an heck he centered her. She went about 50 yds and that was it. As far as loads go I have always used H-4831 w/RP brass and primers in my Mod.70 for hunting -Muddy
