I have been toying with some potential 155gr .30 cal scenars in my .308, in quickload that is, and the velocities that it shows that i can get out of my various setups are just plain atrocious, using federal match brass it was stating 2785 fps with a 24" barrel and 44 gr of IMR 4895 at 51k PSI. Maybe I just play it too safe, but I generally dont exceed about 52k and i know for a fact that the scenar is not really worth playing with unless you are pushing it at LEAST 2875 if not 2900+.
This is unsettling mainly because I really want to build a .260 but cant justify it or afford it, and so the scenars with a 2900+ velocity seem like the proverbial "poor mans" .260 if you will. But from my QL predictions, i cant push them even close to that.
So, in short, I am just wondering, WTF are you guys doing to get those things leaving smoke trails like that?!
QL has always been EXTREMELY accurate in predicting my A-Max and SMK loads almost to a 5fps margin every time with IMR4895 and about 15fps margin with RL-15, so thats kinda whats got me worried, anyone have any input on this at all?
