Yes. The stumps in Iowa are waaaaaaay bigger than the stumps in Georgia. Everybody knows that.
And you can usually buy slick tricks at wally world. That's my ravorite replaceable blade broadhead.
As part of the fiddle factor of building heavier with a higher FoC I think it's not unreasonable to start with a shaft that has a lower gpi rating like a 340 before going to a stiffer spine and heavier gpi, especially if your just adding a little weight. Might not even have to remove old inserts if you just add a footer, and then a heavier point. The main consideration is the arrow oscillation at impact. The stiffer shaft helps to reduce that penetration robbing factor, and with the heavier up front components available, FoC for either arrow isn't a problem.
I'm using the bohning coolflex. It's a stick. you heat the component gently with a torch and wave the stick in front of the torch to just soften it. Add an appropriate amount and seat the insert, with a least a full turn to the insert to help evenly spread the glue, and wipe away the excess. Remove your nocks first so you don't create air pressure in the shaft that could unseat the insert. Great arrow building videos on line.
Prime says it should be here tomorrow
I gently offer that it sounds like you may have just made the point Ranch Fairy preaches; imperfect hit with great momentum.
That's the number one issue when people go heavy there arrow is to weak. When I build an arrow I always go stiff for 2 reasons. I always seem to want to go heavier once I start building and stiff is more forgiving and always seems to tune better for me. My arrows seem to tell me what it wants up front and in the past it has always been about 25 grains heaver then what I thought I wanted. I will never argue with my arrow when it tells it wants more FOC and more weight.
