I bought 2 packs of eskimos. way back in the spring. i hunted with them for the season. i bought a scale the other day and decided to weigh my arrows and there was a difference of around 20 grains . i disected the arrows and found two different eskimos. one pack was bigger and 20 grains heavier. is this normal ? one was 132 grns the other 111. one pack was 1.25 wide the other 1 inch. one pack was 2.5 inch long the other was 2.25 long. is this normal for these types of broadheads? Ive never bought tradional 2 blades before. but I did kill a stud of a 6 point. first tradional buck. and my first doe. six point was 4.5 and was bigger than my 130 8 point. i am thankful . best hunting experience of my life , lol. They seemed to shoot the same.
