I am tuning my bow, started with bareshaft, bareshaft & fletched and have it shooting really good, want to go to broadhead & fieldpoint for final tuning from 30-40 yards. I am shooting 145 grain field points, but can only find 150 grain broadheads, screw on, so is the 5 grains gonna make a difference, I know in the Ashby tuning guide he say's make sure everything is exactly the same. I would not think 5 grains of point weight would matter, but I am asking for expert opinions. Thank you
Keith
I am no expert but I would say no effect at all.
Nope, no difference. :campfire:
I'm no expert, but I don't think it will matter, unless your a lot better shot than most!
You get that much variation in arrow weight from tip and fletching glue.
Did you weigh your field points and inserts on a grain scale and compare it to your screw in broadhead ACTUAL weight, not advertised weight? They may equal out.
Nevertheless 5 gr won't matter.
Not even if it was five grains of gold!
I wouldn't sweat it. By the time you Sharpen you BH a few times you'll probably take that much off.
But you could buy 5 gr. washers for,your,feild,points to even them out .
But like red doggie said unless,you actually weigh everything you won't really know for sure.
The only difference will be in one's mind.
I would like to see kieth bain or someone like that shoot the difference.lol
No! But if it bothers you like it does me, you can do what I do and buy the 5gr brass washers from 3Rivers and put them behind your field point.

Thank's for the advise, that is what I thought also.
The answer is NO.
Nope, nada, zip, zilch, nyet.....
No my bow has about a 25-40 grain swing I can shoot.
No
No difference. I had the exact same problem last year. So I got 5 grain washers and I put them on with my field points (three rivers).
Now everything was a cool 150 gr's.
That said, I don't believe it made any real difference. I just wanted to shoot the same weight across the board...Mental thing.
Usually if an arrow has a 10 grain difference, you will probably not notice much impact difference at 50 yards, unless you are one of the top handful of archers in the world. Thus, the gimmick of weight deviation is just that, a gimmick to scare you into believing weight has a huge difference on impact. We can't even aim precise enough to determine these minimal weight differences!
Of the top three arrow characteristics - weight, spine and straightness, weight is the most easily verified by the consumer. Thus, the focus on weight is highlighted beyond necessity.
How much weight will it take to start seeing a difference for the average shooter at hunting distances?
longbow565...Can only render personal experience with respect to your question.
Assuming arrow is properly tuned and max shooting distance is 20 yards, then my observations of noticeable change of impact is somewhere over 75 gns.
Note: There are much more qualified sources available on TG to address your specific inquiry.
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.
