I got the same notification from Midway. I will probably order them after I get back from New Mexico (leaving next Tuesday). Already have the loads that I plan to shoot there ready to go. Only thing is I can't make up my mind which weapon to use. I picked up a 300 Weatherby (Sub MOA) at a Friends of NRA banquet this year that truly is sub moa with the 168 TTSX's and the Nosler 180 gr E-tips. But I do like (love) my 338's.
I realize that the powder in question was H4350, but, I've had great results with RL22 pushing a Barnes 225 TTSX in my wife's .338 WM. My chrono says 2950fps, with good accuracy. And after several reloads, you still have to de-prime using a resizing die ! memtb
