going on a elephant hunt with your 300 grain head???.....maybe watter buffalo??? or Rhino???
Why put 300 grains infront of a .400 spine alum arrow?? especially if you know it wont work right in the first place???
I let the arrow tell me what to do. First off I start with a arrow weight I want.
I like 10-11gr/lb draw. I like having lots of bows, so this way, they all generally hit the same POI. All usually are 175fps.
Ok, next, I desire greater than 14% FOC, and less than 25%. So I pick the spine I need for all those combos.
For instance, for my black widow longbow. Its 66lbs at 29". So I want ~650gr arrow. So I go thru my carbon spines and figure out combos to get my arrow I want. I use gold tip trads and the wiegh system they have. So I find there 7595's are .3" spined, and to get the flight I want, I add 100gr of brass wieghts and use a 200gr BH. On the nock end, I use a nock adaptor and add wieght up and down to adjust spine. I then bareshaft shoot and add or decrease wieght as needed.
I could have used a 5575 with 125 tip but I would only be like 450gr. Bow is noisier, I don't have my high FOC, POI is little higher than I am used too.
If 125gr works, so be it, as long as it hits my criteria of 10-11gr/lb draw and >14% FOC.
