I too have found some of the newer powders a bit wonky at the higher end. They are great stuff, you just have to slip up on the right combo, ha. I kind of agree with Jock O'Connor that wrote its "doubtful" any bullet going more than 3000fps adds anything...in the field, on game. It was something like that. LR, why sure, it has to help some, especially for a point and shoot guy like me. I know I certainly enjoyed using some rounds that gave me 3200-3500fps, from 6.5/284 and the 120NBT to the .240W(90x) 257W (115NP) to 338RUM (180NAB) but I never shot past 375 with any of them. I'm looking forward to trying out the 110TTSX in this .270, should be wicked on deer/antelope!
