WW, now, now!!! Watch it! (grin)
Thanks for the comments guys, it's appreciated! Lots of views & experiences there! If I go with a lighter setup (too me) it would most likely be in the 375-380 range! This is light in comparison to past setups! I have a few thoughts here as well at present & from past experiences! When talking total arrow weights which also includes broadhead installed, not all setups are created equal! Meaning an arrow that weighs 375grn is not necessarily equal in penetration as another like arrow of the exact weight! I've done similar tests in the past & will do it with my present arrows that I'm considering as well.
For example take a .340 spine arrow & have a finished wt of 380grn, this arrow has a 15 grn aluminum insert & a 100 grn head to meet wt & is spined & tuned to ones setup of 65# - Now take another .340 spine arrow & add a 50grn brass insert & 125 grn head for that 380grn wt total. The only difference here is the head wt. One arrow carries most its wt up-front where the other arrow has its wt distributed through the entire arrow! I've tested arrow combinations as this before, just different wts. The arrow with the strong FOC always wins! My plan was to consider this arrow with the 175grn of wt up-front! It should really perform well at about 290fps. I think it's going to be the best of both worlds, fast & a great penetrator! (grin) If tests are not satisfactory at 38ogrn I can easily bump up brass insert to 70-75grn for at or just under 400grn, this is still light in comparison but I don't think it will be needed!
On a sidenote of interest, my son & I have taken a few elk as well as our crew, (5 of us) I will venture a guess here, but a good one, that we receive aprox 25% pass-throughs on elk, that's 75% where arrows do not punch through both sides! This is with our present 420grn to over 500grn total arrow wt setups. From my experience I honestly feel that pass-throughs are over rated, yes I like them but it's not needed, I like the fact that a razor sharp head is in the animal carving him up with every step he takes to add to the damage & hopefully a quick recovery. As I mentioned, winter is slow in leaving & the snow is still piling up so I'm tinkering here! (grin)
