Going to set my daughter up with a 400 gr FMJ set at 50 lb draw weight. Her DL is 24". Tip weight will be 150 gr total, single bevel Cutthroat broadhead. More weight up front to help with "rapid" stabilization to maximize penetration potential.
Howdy Road Runner.
I have been playing with a 43#/26" bow for a spring project I am running on the Ranch Fairy channel as noted. Tuning this rig was actually quite frustrating when I "obeyed the spine charts". But I am a total contrarian. If what is common doesn't work, I throw it out and wander off to find out what does. This keeps me from having too many annoying friends so I can concentrate.
Here's what shoots:
1. 28.5" ICS and Gold Tip 400 or 340 spine + 100 insert + 150-300 grain points. Here's what is interesting... we cut these same spine arrows to 26, per the STUPID SPINE GUESSTIMATER which stiffened them a bunch. The result is a small, very consistent left tail kick I could not get out of it. But, the 28.5" will bare shaft easily. So if it flies perfect, it flies perfect. 28.5" it si.
2. 26" (crazy huh?) GT Kinetic Pierce 300 with 200-300 grains up front. DARTS
3. 28.5" 300 spine Gold Tip Hunter with 150 grain inserts and 125 heads.
4. Here's a mystery. 26" 2219 Easton traditional aluminum with 150 grain point. Bare Shaft Darts. I still can't figure that out.
I am going pretty heavy, obviously. So, I shot the 28.5" arrow in #1 above, with the 100 brass insert and 125 field point yesterday. It was absolutely beautiful. That might be where you want to land for total arrow weight from your initial post with FMJ. Guessing
Anyhoo, if the FMJ's shoot, awesome. If they misbehave a little bit or won't group consistently (the latter was my issue, the "on spine chart" arrows were mischievous and just had a few fliers that I couldn't understand), throw out the bathwater and shoot anything.
Perfect arrow flight should always be goal one. But with low poundage and draw length, its a HUGE"er" thing.
