need to beef up an arrow

[Conner Parry]

i am shooting a 50lb longbow, i have some 2016's cut @ 29 inches, i will probably shoot a 145 grain head. i am wanting to get into the 600 grain mark with this set-up, any ideas ?

You will already be at about 520 grains with your setup.  You could try adding a 75 grain insert.   Frankly, I think 540 grains is plenty heavy for North American Game, especially if it's flying perfectly.

arrowbolic steroids?    
Sorry, couldn't resist.

actually I have 175g points and my arrows hit 522g, almost exactly the same as yours, you can combine a 125g point with a 100g adapter and get 622g, thet should be your ticket
