[QUOTE="DANTEC, post: 28715, member: 685"] go over 3000 fps awith 162 gr in 24 or 26 inch is very difficult without hight pressure , only way to reach 3100 and little more is to use a 28 or or a 30 inch but 3300 and 162 with only 7 REM MAG capacity that [img]images/icons/grin.gif[/img] [img]images/icons/grin.gif[/img] velocity measurement was a problem before accurate system and adfordable system are easy to get , even now only average velocity on long string enought can be use as serious data , dont forget that an instrument display is not the TRUE And you need to check calibration before ; if a commum error is 2% on display value ( summ of error on electronic/optical low cost system ) that make 60 fps ( +/- 30 fps ) on 3000 fps that not to bad to get amazing false velocity . good shooting DANTEC [/QUOTE]
