I need some arrow advice please.
I am currently shooting Victory VForce Elite 350's that are approximatley 390 grains total arrow weight. I would like to go up to 430-470ish grains but keep my 100 grain broadheads. My local archery shop recommends and carries the Victory RIP TKO 300's or the VForce 300's.
I purchased some 125 and 145 grain field points and brass washers so I could chronograph and get some KE/momentum numbers. The guy at the archery shop gave me the information below:
100 grain point - 390 grain total arrow weight - 302 fps - 79.78ft/lb of KE - 0.528/m
130 grain pont - 420 grain total arrow weight - 297fps - 82.64ft/lb of KE - 0.557/m
150 grain point - 440 grain total arrow weight - 288fps - 81.39ft/lb of KE - 0.565/m
Bow is a Bowtech Insanity at 70lbs. Arrows are currently 28" from insert to end of the nock.
The RIP TKO's are 8.8gpi and 0.204 shaft ID and the VForce arrows are 9.7gpi and 0.245 shaft ID.
The RIP's are a smaller diameter. They have a SS Shok insert/outsert (?) or a brass insert. With the brass insert my broadhead diameter is bigger than the arrow diameter and would stick out past the shaft. Would this affect arrow durability or anything else? I have read some negative things about outserts in the past. Do they still have issues?
Do the numbers above (speed, KE & momentum) seem accurate? I thought the 150 would have more KE than the 130.
Is 2, 3, 4... ft/lb of KE a significant enough difference to make the change? What about the momentum? Is a difference of 0.037 worth changing for? Could I add weight to my current arrows and if so how much with a 350 spine? If I go with a dozen new arrows, which direction do you recommend?
Thanks in advance for any help!
