So I ended up going with the FMJ's after my other post and people's recommendations. Just finished fletching them, gonna be cutting them tomorrow and finishing them up!!!
I think so.. and the with speed that the GX2 puts out. I should be abel to get some pass-throughs on deer this fall. Should be around 422 or so when all said and done. They are smaller diameter than the other arrows I was shooting, so I'm looking forward to them.
