[QUOTE="PRCLITE, post: 2089755, member: 77124"] Just ran it through my gen2 caldwell chronograph which I've only used once with my bow. it seems to be an accurate chronograph thus far. I fired 5 rounds and all were within 8fps with an average of 3086fps. I've plugged those numbers into my ballistics calculator and it still doesn't add up to the field verified 3180. I know the chronograph isn't always exact but it's still 80-90fps slower than I verified in the field. Please note that I am now at sea level and it's a good bit warmer than where I verified in the field so that could make up for the difference but after entering my atmospheric conditions, it still didn't add up. I'm glad I've got the rangefinder I do because it compensates for atmospheric conditions as well as the coriolis acceleration which could have certainly made a difference at longer yardages. All in all I've got my solid field data and I've got a great shooting rifle. My rifle has a 24" barrel so I know that's not the difference since that's what the advertised speed is based off of. Did I just get a great barrel? Not sure. [/QUOTE]
