[QUOTE="missourideere, post: 1863662, member: 90713"] I'm shooting 73.5 grains of imr 7977 with a 208 a max book shows at 75 grains I should be shooting 2852fps. I dont have a chronograph so I just checked how much bullet drop was from 100yds-400yds it dropped 22" i put that in my calculator and it comes out to @ 3200fps. Is there something im missing? My barrel is 2" longer then the book used to test [/QUOTE]
