The arrow from an 80# bow will pass thru and put 14" in the ground. So what's the point unless you're planning a trip to Africa?
You have some great points , I am very new to bow shooting, just bought this bow about 3 weeks ago. My reasoning ( which may be dumb to you all) to want to make my bow faster , is to make it shoot the same spot on the target from 0-35 yards, so I was thinking hoping by making it faster, the arrow would fly the same path for a little longer before it started to drop off. Before i took it to the shop last week it was shooting 67 pounds, arrows were 5575s with 100 grain tips, I can't remember who they were made by though. The guy put more twists in my string and got the poundage up to 71,which changed the fps from 289 to 295, then I changed to the Easton flatline arrows with 85 grain tips and it chronod at 311fps. Before I could shoot out to about 27 yards before It started dropping, Now around 30-31 yards , so 4 more yards would be swell to make up for if you all kmow of anybody that could make or makes some heavier limbs could you tell me or link me? I'm shooting 3d targets all this summer to try and get to be a egret shot for next hunting season, thanks for all of your help so far it's really appreciated as I'm a real beginner to this
