I'll post my results and maybe a few of ya'll will look at in the future and help you out.
I decided to take a small length of airline tubing and fill it with lead shot, about a 2" piece. i wrapped it in tape and rammed it from the nock end towards the inset. now I have my 260 grains up front.
i wrapped my feathers to get a bareshaft and started shooting at 12yards. I could tell nothing different and was hitting my arrows almost. I moved back to 20 yards, my group was not as tight but the bareshaft arrow was in with the rest. GREAT!!
I glued up some broadheads, 100 grain steel with a 160 grizzley, spun until true ,cooled it, and shot it(fletched) flew like a homing pigeons, i can hit a three inch circle nicely with the blades.
I am ready to hunt and I have 22.3% FOC and a 597 grain arrow. I like the 650 grain area, but as you wise ones told me, were talking feathers now.
The thing I dont get is that my 200 grain setup bareshafted the same, I am surprised that another 50 graing didnt effect the results, at least with what i could tell.
I hope someone else will learn from my experience and to everyone who added to it a great thatnk you to you and I hope to post a first BIG game trad kill in the fall
Happy hunting
