Yes they are very different, powder, charge weight, full length sizing and trimming are key for the guy who wants to shoot his rifle vs the guy who wants his rifle so shoot him as it explodes in his face! Don't go chasing speeds if will get you hurt.
Which Armalite rifle do you have? Use the 175 SMK the 168 was designed for 300m it will go further of course but your going to loose stability around 700m.
Varget or R15 are fine powders, I would suggest the CCI#44 primer to mitigate the risk of slam fires, due to the weapons floating firing pin.
