Here are charts for 2 different weight arrow that are PROPERLY spined and setup for my bow.
I have posted this before but pay close attention to the speed and energy.
PAY EXTRA ATTENTION TO THE DROP PER YARD DIFFERENCE.THIS IS WHAT WILL BE YOUR MISS DIFFERENCE IN A HUNTING SITUATION BETWEEN A LIGHT AND HEAVIER ARROW.
This example isn't using extreme differences but 61 grains should give you an idea of what to expect.
That's impossible. You can't have 2 seperate arrow weights have the right spine for your bow!!!!
NOT IMPOSSIBLE
I believe I used a FMJ for one and an ACC for another.The spine deflection for both was very close.
An Easton aluminum 2115 has a spine deflection of .462 and a total weight with my setup of 433 grains
An Easton redline 460 has a spine deflection of .460 and a total weight of 334 grains.
Right at 100 grain difference with almost identical spine deflection and both spine perfectly for my bow.
This is using the same insert weights and fletching.I didn't feel changing the insert weight was necessary to show the comparison of spine.The aluminum shafts would be even heavier if I changed that.
When I was talking about broadheads,I was referring to the large cut expandables,they are designed for massive damage,NOT penetration.I have a lower energy setup and therefore,I utilize heads that have penetration more in mind,smaller cut.
My daughter uses 2 blade heads that are the best for penetration but don't do as much damage.
