I have a combo that tunes well 225tip 11 grain insert =231 total and would like to change to 50grain insert and a 175 tip = 225 total(I have several 175 bh). Arrow 1535 gold tip trad cut to 281/2 1 inch footing of 2117 12 grain 3 4inch fletch 12 grain nock bow Dale Dye 48@26 (I draw 27)12 strand ff . will they tune the same?
In my tuning experience small differences like that do not effect the tuning. I have even had 25 grain differences and it still didnt. Most of my bows are cut at or close to center so that can determine how wide of a spine range your Bow will tolerate too.
I think is a mistake in the math there 225 tip 11grain insert = 236 not 261 total. I don't think I would see the difference for 11gr but it comes down to how is the bow cut.
yup :banghead: math mistake should 225+11 =236
You won't notice the difference. Neither will the bow. Don't worry about it.
As you move weight back, it stiffens the spine, the same as decreasing point weight. So you have an 11 grain actual weight difference, plus whatever the effect might be of moving the weight back. I'm sure you could see the difference if you compared bare shafts with both configurations. Ideally, if your bare shaft was a little weak with your first configuration, this would move it in the right direction. If your bare shaft was a little stiff, this would move it further in the wrong direction. Whether it will make enough difference with a fletched shaft to bother you is something you'll have to observe for yourself.
I agree with McDave. I've found that the difference between lighter tip/heavier insert, and heavier tip/lighter insert is small, but there. I've seen it in my bare shaft tuning. But with both fletched, I couldn't see a difference. The fletching masked it.
Probably won't matter but shoot the new combo field point and broadhead and know for sure.
that little amount of weight makes very little difference. You will not notice a thing.

I've occassionally had 100 grain inserts change things a bit, but not the 50s.
I was once told adding/subtracting weight to the tip or nock end of an arrow can affect spine in small steps. Rule of thumb I've seen some use is add 5 grains to the tip and spine of the arrow goes down about 1 pound. Add 5 to the nock end and arrow spine goes up about 1 pound. Subtract the weight and get opposite results.
This may explain why several have commented changes of around 25 grains have little noticeable impact since the spine impact is about 5 pounds. I don't think most tuned set ups will show a negative impact with this level of change.
Depends on if your original arrow was tuned perfectly or if you were off a little bit in the first place. an example would be 175gr's would be ideal flight for you but you are shooting 200gr's. Going up to 225gr's is really now a 50gr jump and not a 25gr jump.
No. You, nor me, nor anybody here can hold steady enough to tell a difference.
They won't effect tuning but they will effect forgiveness. In my experience the closer to being in tune you are the more forgiveness there is when it comes to short drawing, over drawing, a poor release, and other things.
That being said with good form and adequate fletching you could shoot a group of .400 spine arrows, .500 spine arrows, and .600 spine arrows and they should all group together.
This has been my experience at least.
That being said 10-11 grains is nothing unless you add that weight to the nock end of the arrow.

That right there says it all :thumbsup:
