As some might remember, I decided to switch to CX Maxima Blue Streaks for my new setup. I ran the numbers through OT2, tweaking, etc., until I came up with what I thought would be the perfect whitetail arrow for this season. Specs as follows: Bowtech Destroyer 340 @64lbs, 28" Draw Length Arrow: CX Maxima Blue Streak 350, 27.5" in length. Bull Dog collars and cx nocks. My plan, based on the OT2 program, was to use a 125gr head up front on these. This would give me an FOC of around 13.5% and a total arrow weight of 400gr exactly. As I built them, they all came in right on the money, +- 1gr. But, here's where it got interesting for me. I discovered the 125gr points I bought weren't actually bent. The "shank" of the point has quite a bit of play inside the insert. If they're not screwed in carfully and spun, they will wobble like crazy. I went back and "fixed" 3 arrows with the 125gr heads until they spun well, and went and shot. Then, for the heck of it, I took 3 100gr points that I knew spun well and shot again. I did this all evening and have found that for some odd reason, this bow/arrow combo shoots lights out better with 100gr heads. Broadheads shoot exactly like the fieldpoints and wound up ruining an arrow. I was really hoping to up my FOC and penetration going to a 125gr head, but the way this thing is shooting with 100's, I can't help but think I'm going to stay with them.
Get some Easton field points in 125 grain and then recheck things. They will spin true. Lancaster's has them. Not much difference between 100's and 125's so whatever works best is the direction I would go. Sent from my DROIDX using Tapatalk 2
tfox, I plan on getting some other 125gr. As I mentioned.. I always thought field points were field points. It's weird, the shank, or non threaded part of the point has quite a bit of play inside the insert. If they're not screwed in carefully and snugged up, they will be off. I've never seen such a thing before. One option I'm debating on now is getting insert weights. 100gr broadheads are much easier to come by around here and the insert weight setup would allow me to play with weight much easier.
You could turn your DW down a half turn and see how the 125's fly. There isn't a lot of difference between the two but I'll take more over less, when it comes to weight and FOC, any day.
There are some mighty good 100 grain heads out there such as Muzzy, Slicks and a plethora of "expendables." The bottom line to any setup is how well it shoots and it sounds like you have really dialed in at 100 grains. Time to start finding something to shoot at now.
I had some bad fp's like that once and then I tried the Eastons and they fit like glue in points. I agree about weights. That's what I did for my son. 75 grain brass inserts give some serious foc in his. .600 axis and we both use the same 100 grain magnus stingers. Sent from my DROIDX using Tapatalk 2
The guy at my bow shop weighed a 90 grain Muzzy broadhead and swears that it weighs 98 grains. Hence, he set me up with Muzzy 90's. Strictly because they're easier to find, I buy 100 grain Muzzy's. But I've never weighed them. Have any of you?
It's always amazed me at what a little weight different in the front of your arrow, or a little play/misalignment will do to your arrow flight. Different bows seem to like different arrow weights and FOC percentages as well. That's why being able to tweak/adjust your setup is so important to get the best possible flight. IMO, if you're shooting that well with 100 grains just stick with it. A 375-380 grain arrow is going to kill a whitetail just as dead as a 400 grain arrow, especially if you're shooting that well.
Justin, you're absolutely correct. I've had plenty of tinker time this summer with this setup. I've killed many whitetails with arrows weighing around 370gr. All, with the exception of two deer were complete pass throughs. The other two were just off shots that still had more than enough penetration, even splitting bone, to get the job done. My main goal was to find a combo that tuned well. I really thought the heavier weight up front would be the ticket to get a better flying arrow. But the 100's on the front seem to be very, very consistent. Looks like I'm ready to roll!
