I also went down the Ashby rabbit hole. Here are my findings and results:
My original goal was to shoot a 650g arrow with high FOC. I went with a Gold Tip Hunter XT(same arrow I've shot for YEARS). I cut it a little longer, put a 100g weight in the front, no arrow wrap and no lighted nocks to keep all weight up front. And then I went with a 200g head. Total arrow weight was 624g with 19% FOC. Boughr a brand new V3X 33, max out 70lb limbs(probably around 74lbs). That was shooting at 258fps.
So I sighted the bow in at 20 just as normal.
Noticed immediately how quiet everything was and at the distance it seemed to be fast enough.
I then go back to 30 yards. Now I start to notice the speed...arrows are considerably slower, can already see the arch on arrow flight. From 20 to 30 my arrow is dropping roughly 4"....quite a bit
I move back to 40. Now my arrow is dropping 15". Arrow is soooo slow to get there. I immediately and unhappy with the results.
I keep the same arrow setup but instead just use a 100g head, so now my total arrow weight is 524g with 15% FOC. This is what I am currently to this day.
So now we move to the broadheads. I decided on shooting Iron Will single bevel heads. I like the idea of SB as well as the warranty and being able to resharpen my heads.
I shot my buck at 8.4 yards through lungs and top of heart. Perfect 10 ring. He ran 40 yards stopped, I put the binos on him and just remember thinking that he wasn't bleeding well. He stood there for 30 seconds then ran another 20 yards and died. Upon tracking the animal there was VERY little blood. Interstingly enough when I gutted the animal the lungs looked like I shot it with a smokeless muzzleloader, absolutely destroyed on the inside but nothing on the outside...I didn't think much of it at the time. Well a good friend was also shooting the same head. He shot multiple does with them and same results. Dead deer quickly, destroyed on the inside but no blood on the outside(he can chime in on those results)...
So I contacted Iron Will and told them our findings and they recommended trying the wide series heads. So I ordered one head and shot a doe with it. She only made it 10 yards so my test wasn't great BUT there was significant blood on the ground from her. I ordered more Iron Will double bevel wide heads
So if I could do it all over again (which I will be)...
I think the Iowa Whitetail hunter(compound bow) should be shooting 275-290 fps with as much FOC as you can at that speed all while having a total arrow weight of 480-515g. I still believe I am going to continue to shoot the wide series head but if not it will be some other fixed blade head. Also I believe shooting a micro diameter arrow is important which I will be switching arrows this next year.
