While I was in the bow shop today I just wanted to try the 70# mods for my Vertix. I was amazed at how little difference there was in those and the 60#. so I went with it and got the 70#s. I was very pleased at how flat and accurate they flew and how the bow remained quiet. Now, My question is about arrows. My current arrows are on average 390 gr. the bow is exactly at 70.4 lbs. so that puts me at 5.5 gr per pound of draw weight. I have now question about weather these arrows and rage heads will do fine in most situations on VA whitetails. For years I shot lighter arrows with rage heads at 70+ lbs. but, I know there is a trend moving towards mid weight arrows. Something in the 415 gr and up for 70# .. I could go out and buy new arrows, likely the pile drivers from carbon express, or I could add a lighted nock and get to around 415 gr. or I could just let it be at what it is. all will kill for sure, but I just wanted to hear the pros and cons of options and your opinions. I know there are a lot of heavy arrow guys here, and some mid range guys and maybe a few light weight guys as well.
One of the best things I did was go to and 11.3 gpi arrow. Hit hard at 475 grains. Buy the pile drivers go with a 125 grain BH and a lit nock.
I believe you are way under spined now with you moving up in poundage. I don't have the arrow chart, but believe min. Should be shooting 340 spine. Sent from my SM-G900V using Tapatalk
I am 90% sure we went over this same topic with I thought the same OP about 4 months ago...but I digress. Holt is correct you are likely going to be underspined even with a short draw. Also, don't add weight to the back of an arrow thinking it's going to have much of an effect on anything if you are spined correctly. My lighted nocks fly exactly the same as my non-lighted nocks out to 80. Weight FOC is what matters. But when you are underspined already, adding weight to the back of an arrow is bad. Bad. Going to exacerbate whipsawing.
Doodles, yeh we did go over this topic when I was shooting 60 lbs ...Now I am up to 70 again. I have always shot the 400 spine with 70 lbs.....now, my arrows are short and I mean 26.75" short and that is still leaving some good over hang.. I tried 340s once but I couldn't get em to tune. I would love to be able to go to 340s. would help me get weight up...easton chart disagrees!
With only a 100 grain head and that short of an arrow I think the 400's may still tune fine. I think your super close on spine though. If you add any weight at all to the front you're going to have to go to 340 spine. I personally would just see if your current arrows will tune fine, paper or bare shaft. Definitely go to a 340 the next time you buy hunting arrows, perhaps even a 300 if you want to add extra weight to the front. I have some 400's for 3d arrows. I'm a 27.5" DL, shooting 65 lbs with a 330 IBO bow. Arrows are 26.5" long. With just a standard 12 gr insert and 100 grain FP's they fly ok. A bit underspined though. My hunting arrows are the same length but in a 340 spine. I added 20 extra grains to the front and they wouldn't tune with a 125 head, had to stay with a 100gr. Extra weight on the front eats spine fast.
