You'll most definitely need to use a cut on contact Broadhead to shoot through the netting, don't forget to wear black gloves on your bow hand, it's the closest thing to the deer,
And you don't want have the netting too tight on the windows, if you have it loose, it will flex with your arrow, and it will not affect your shot accuracy. I have used a double bull for the last two years, there a great tool. As long as you're blind is brushed in, and you use the screen netting, you will do fine. When you brush your blind in, make sure that you break up the straight lines of the corners and the roof.
Enjoy your ground experience
