Sieg...I've reading your posts since I joined this great site a little while back, and I've found them cogent and informative. I too, have been loading and shooting lo these 3 decades or so. You are correct, there will usually be a sweet spot for bullet weight/velocity/ sectional density when loading for extreme accuracy in rifles. I've just begun my tinkering with .30 Luger (last project was .25-20 Win out of a Contender, to show you how weird I am!). However, the extremes of ballistic performance from a rifle don't neccesarliy correlate to pistol catridge performance. I've just finishing refurbishing my 1900 Parabellum and have fired some Win and Fiocchi ammo that's chronoing about 1180 fps....its grouping superbly. I'm given to understand DWM specs were around 1250 from the 4 3/4 bbl. I'm going to put together a 6in .30 on another Luger and I'm gonna strive for around 1400-1450 with it...I'll let ya know if it stays on paper
