Changing point weight
I'm thinking of upping my arrow weight a little and have some 175 grain points and vpa terminators from my recurve setup. Not sure yet if they will tune with my arrows. My question is does anyone use that size broad head and are there any accuracy issues with the larger head from a compound. Thanks
Not sure what your question is. If your current set-up is with 100 or 125 grain points, 175 will weaken the arrow spine a lot. Can you compensate with lateral adjustment? Maybe. But that's asking a lot. Better to go with a stiffer shaft, I think.
Just wondering if a 175 grain 3 blade would fly good out of a compound out to 40 yards. I understand the turning issues and what I'll need to do for that. Just asking for any experience shooting a head like that. Have no problem tuning them to my recurve just never used anything over 100 grain from compound which is usually a more compact head
There's one way to find out.
Shoot one and see how it flies. It might work just fine without changing to stiffer arrows, who knows.
iv been shooting the same compound & arrows since 2005 & as I turn the pounds down on the bow iv increased my point weight. iv gone from 70# & 100gr heads to 60# & 150gr heads with the same shaft & get great flight
If you tune the bow tonyhay set up it’ll fly great
The 175s will be fine if you can get it to tune my wife is shooting 165 grain heads with 75 grain brass inserts to get her arrow weight up.
I’m shooting 175 grain VPA with a 100 gr. Insert - flies great out of my compound and hits hard.
I'm gonna try them as soon as the weather warms up enough to shoot and see what happens. Thanks
I'm really thinking about going to heavier heads as well.
I don't see a substantial downside.
I use 175 grain VPA's out of both my recurves and compounds. I get great flight out of eash. My compound arrows are only 26.5" .400 spine and shot from a 66# bow. My recurve arrows are 28.5"s and .600 spine, I draw 27.5"s and shoot 43-47# recurves. If you have room to trim a .75" or so off your compound arrow that will stiffen it enough for the extra 50 grains your 175 will add. Shawn
I am guessing if your bow is shooting a 100 grain head and arrow is spined properly it will be under spined if you change to a 175 grain head. What is your draw weight, arrow length, arrow spine?
Bow is mathews creed email@example.com"and arrows are 400 spine cut to 28.25". Currently I'm shooting a 100 grain point but my tune was originally for 62#. Had to drop in poundage and haven't retuned yet
If you have a tuned rest, if your arrow is matched to your bow, if you have a broadhead with a reasonable profile, you should be good. The heavier setup will slow your arrow and give you some easier aerodynamics.
1: Shoot the bow with the heavier FP and see if it groups well. (Don't worry if it is "off target" and needs adjustment....only focus on grouping.
2: if the arrows group well, then shoot them through paper starting at 3 yards and go back to 10 yards.
If these two are good, chances are you are money.
I am going to bet a 400 spined arrow at that length and poundage will be to weak of a spine for a 175 grain head. Maybe if you cut your arrows a inch or inch and quarter. That would help some. At your draw length you should have some room to cut off.
I shoot a 400 spine arrow 27.5” inches long with a 100 grain tips @ 62# it is not to far from needing 340 spined arrows.
Maybe someone with software will run it for you.
Just made the same switch... shoulder issues caused me to turn weight down so I put 175 grain field tips in my FMJ 400.
For the FMJ s I had that didn’t have inserts in them I put the brass break off ones at 50 grains and shoot my 125 grain tips. Both arrows hit the same spot.
The 175 got a d the 125 hrs with the 50 he insert. Not sure what draw weight I’m shooting though just turned it down till arrows flew well
