20 grain point difference?

[Stixbowdrew]

I have a little dilemma, I am currently shooting 145 grain tips on my 2117s, but I came across some 165 grains Landsharks that I would really like to shoot out of it. I am planning on trying a 165 tip to check flight, but I'm bored at work and wanted to poll the group to see what thoughts or personal experience there was in dealing with this. Thanks!!

You didn't mention what your actual draw weight is for that set up. Adding 20 grn to your arrow may weaken the spine enough that you will have to go to the next spine rating.Others will chime in that know what that would be, as I'm am not that familiar with aluminum arrows. They will need to know your draw weight.

I forgot to mention that you will need to give your draw length/ arrow length also.

Oops......bow type will matter also, whether it is center shot ect.

Unless you are close to the edge of being tuned correctly, you should not notice a whole lot of difference. Since the points you are going to are heavier, you may need to shorten your shaft a bit to get them just right again.

Bow is a b handle mag riser 62" 50@ 28" I draw 30" arrows are 31.25"

If you were paper tuning it would probably show about a 2 lb spine difference.  With the setup described I think you will do fine with the heavier point.  They may shoot even better.

I agree with Fletcher.  Most folks can't tell a 50 grain difference on their arrows.  20 grains isn't enough to worry about.

I didn't think it would be an issue just thought I'd get some opinions, the arrows now bare shaft great will try it tonight.

Bare shafted with a 175 field tip.... Didn't make a bit of difference grouped right with the 145 fletched arrows and flew true thanks guys!!

  Shows what I know about aluminum, I'm just a wood guy.

Might have to play with brace height a little or move string silencers a bit but 20 grains should not make much difference if any noticeable difference.  ANYTHING you do to change the total set-up will have some affect.

You never know until you try it.  20 fr as in also means more with a 450 grain arrow than with a 550 grain shaft.
