so with squirrel season 3 days away here some pople are stumping i made 4 5" bag targets with the old bags from work that we throw away and i covered them up with CAMO duct tape really makes you pick a tiny spot and focus hard to see it, im amazed with how well they stop an arrow i shot a 800 grain arrow out of my 80# howatt bow and got 3" of penetration on it i shot one WITH A BROADHEAD (arrow weight on this arrow 637 grains) and just barely poked through it (targets about 4" thick) so i think i found my cheap new roving targets/baseball pitch practice
