My son was shooting Muzzy broadheads 75 grain until he got his new bow Bear Lightsout. His draw length went from 28 inches last year to 30 inches this year. He is shooting Axis ST carbons 400, I was told he needed to step up to 100 grain muzzy's due to his draw length and weigth of his arrow and poundage he pulls. The shop owner said we could get a 25 grain washer to add to the 75 grain broadhead but the arrow may not fly true. So I went and purchased the 100 grain broadheads. Can anyone shed some light on this subject is this true

If your asking about the insert washer I can tell you my experience. When my son went from a youth bow to an adult bow I also decided to try the inserts to save on the cost of upgrading from 75 to 100 grain broadheads.

Needless to say the grouping he got with the inserts and a 75 grain broadhead was not that great. We know this because I let him try some of my 100 grain broadheads with the same arrows he shot the 75 grain and inserts. His grouping with the 100 grain broadhead and no washer was a vast improvement.

In my opinion your better off just matching a good broadhead to the arrow he is shooting now. forget trying to use the 75 grain and a washer.

Thanks Dave
Appriecate the info, as soon as we're done sighting his bow in he's gone to try them.

I think it's a good idea just to upgrade to the 100 gr muzzys.

What poundage is he pulling? with that 30 inch draw, if he's pulling much over 62 - 63 lbs, he'll be borderline weak spined with 100 grain heads. the 75's may fly better.

The Bear Lightsout that he's got has a range of 50-60 pds. The draw weight is set right now at 46lbs. Which a little practice I believe he'll be up to 50lbs by mid deer season. My son is 13 yrs old and is 5' 11". Tall kid but he's was lifting this summer for football this season, so I believe that helped him out. He can't wait for opening day.

As long as the overall arrow weight has enough grains per pound of draw weight, he should be fine with the 75 muzzies. I wouldnt worry about being underspined, with the light draw weight. If he bumps the weight up next year you' probably need to go the 340 spine.

He must have long arms, I am 5'11 and my draw is only 28 inches!

@ 5'11" a 30" draw does seem long.
Spine shouldn't be an issue with a 50-60# bow and a 100 gr. broadhead as long as the arrows aren't full length.

you are exactly right on this!!!

It might be wise to have him "re-checked" for draw length. I am 6'2 and have long arms and I'm a 29" draw. A bow that is too long is just as hard to shoot as one that is draw weight heavy.

Good luck!
