.047(nitrous) and a .026(fuel) are the correct pills for a 100 shot, so a .046 and a .032 is more around roughly a 75ish shot....a .032(fuel pill) is good for a 150ish shot, and a .046 is like a 96HP shot(nitrous) pill....so do the math and judge for yourself but im goin with around a 75ish shot size on your current pills....heres the link i got my info from. all nitrous company's nitrous pills are the same as far as the size....
