I recently switched to feathers and my concern is that my arrows may be too light for Moose. My arrows weighed 415 before and now weigh 380 gr. I shoot a SQ2 at 75 pounds and 27 inch draw. My broadhead tipped arrows are flying good and I am shooting 5 inch groups at 50 yards. I am planning on using a Phantom 4 blade broadhead(cut on contact). I could go back to my Terminator Hunters then that would give me about a 480 grain arrow but I kinda like the flatter shooting more accurate Gold Tip Camo XTs' or should I just get some weight tubes or what??

At 380 grains, I' d say you' re right to be worried about being too light for moose. I' m sure somebody, somewhere has used a 350 grain arrow to kill a moose. There are also people that ride motorcycles without helmets. Just because it' s done doesn' t make it a good idea. Go back to the heavier arrow or weight up the GoldTips. If you' re worried about the trajectory, just stand closer to the animal to shoot at it.
