Thank you friend. That's about what I'm thinking.

no difference at all. i do exactly the same thing.

Use it to your advantage as a psychological boost.  Since we tend to get a bit excited at times and occasionally short draw when live game is the target, you can shoot with confidence knowing that extra 5 grains of broadhead weight is exactly offsetting the poundage lost from that last 1/4" you didn't pull completely to anchor, lol!

When Roger Rothaar was developing the Snuffer he did some indepth tests on weight variations and impact/flight differences.  If I remember correctly, he found little if any at normal hunting ranges of 50 or so grain difference in broadhead weight.

Say five grains is 0.8% of the overall weight, then it is about the same as being 1/5 of an inch difference between draw to anchor between arrows.  I doubt most of us are that consistant in field conditions.  

So: no.  I shoot 145 gr Judos with my 125 gr field points and 130 gr broadheads.  No noticable differance.

No!

My vote is no. Go shoot and have some fun!

+1 the difference doesn't mean anything but the thought of it being different bothers me and confidence is important so to quell my OCD the washers are good

Archery is a mental game, so if ya got it in your mind that the 5 is going to mess you up, then add the washers and have peace of mind.

First off I am trying to help not confuse.  Just curious about your tuning arrows. I am shooting arrow with wraps and feathers.  So my "bare shaft" is actually not bare.  I take a fletched arrow and just cut the feather off and leave the quill.  this gets the most accurate weight representation when doing the tuning test.    

It sounds like you a serious with your thoughts on matching the weight of your arrows and tuning. Check out this video.  I only shoot the "bare shaft" with the quill attached.  more closely represents the weight of a fletched shaft.  My "coach" arrow" as Ken Beck puts it.

This is what I did, most likely doesn't mater but, make me feel like I'm doing it the right way.

Why not grind off that 5 grains from either the broadhead back or from the inserts?

Regarding does it make a difference, why not get the weight right on?

As a carpenter years ago my boss went ballistic when you cut a stud even 1/8th inch off. "Its just as easy to cut it exactly right as it is to cut it exactly wrong" he'd huff. And it made a difference when we would plumb and square the walls and set the ridge.

Details matter.

To all that say it matters, do you weigh how much glue you use on an insert? Do you weigh the insert? How about your feathers? Do you weigh the glue used to adhere them? Weigh each feather? How about....oh, never mind, you get my point.

My opinion, no it absolutely will not matter at all. However, there is an anal side to me that acknowledges that tradtional bow hunting has more uncontrollable variables than I care to count, so why not control the variable that are quite easy to control when given the opportunity?

5 grain washers, removing 5 grains from brass insert, etc etc are simple fixes to a relatively easy variable to control.

Because in this game on variables, I want as many of them as possible to go away.

No difference in 145 and 150 grains that I can tell, or between any grain difference that is as slight as 5 grains.
