i only have an Oz scale and it shows up as 0.6oz
Long range with the 245 and 295, ive used and all shots were enter/exit. Ive even used 150 grains RS loose with a 295 and that shot was a clean pass-thru shot that drop the deer. Lungs, heart,liver were, Well they didnt look like they are supposed to .

I just weighed two .440 roundballs that are 130 grains each and they shown up as 0.5oz. So theres 160 grains right there @ 0.5oz. I wish i had another powerbelt to weigh off the actual OZ weight when new.
