I am worried with the 225 grains up front and 80 pounds the 300s will be to weak.
You would be borderline but that would depend on the cut length. I don't think there would be any issues getting them to tune.

Here is an option for you to consider. A GT APG Hunter in 75/95 cut to 28.5" with 100gr brass insert, 150 gr broadhead, Unibushing adapter w/ G nock, 3 Blazers.
That would be even more under spined than the .300 with all that weight up front.
im guessing you are shooting the dangerous game fmjs??? I want more foc. If i want to get to 650 grains i will probably shoot the Alaska bowhunting supply Grizzstixs... I may make up a few different batches and see which one shoots better

It would tune just fine. Perfect example is Cam's new 90#. You punch the numbers for the arrows we made into any archery program and they all come up way weak yet that bow was shooting bullet holes in 4 shots and grouping great. 4 of us shot that same bow and arrow and all of us had the same clean hole through paper. You can't always just go off of numbers.
Yes. He's been shooting the Injexion FMJ 400s for the last couple of years. He's been using the Muzzy Trocar D6 heads this year.
For his 90# Faktor he's shooting FMJ DG 300s.
Just throwing this out there to keep things in perspective in relation to spine. When shooting the FMJ's they react a little stiffer than an all carbon when it comes to dynamic spine.
Due to weight gpi gain?
Shane, I have a Spyder Turbo 70/29.5 with Axis 300s. I had to turn the bow down 2 cranks to get it to BH tune. I want to run 150 grain heads so I am planning on Gold Tip 200s. Thoughts?
