Sorry but I'm new at this archery stuff. Are you saying you are getting 300 fps through a chronograph? In asking about speed to the guy who sold me my bow ( bought at Basspro) he explained to me that while my bow was rated at 309 IBO it would likely shoot around 240fps. In a test I read I think in Outdoor Life they tested it at @225 fps I believe. I bought a reflex grizzly, 60-70 lb. I have it set at 27" (its a 27-30) and 70 lbs. My arrows are 27 1/2" long and weigh 11 GPI (red head carbon fury 350) and I have 125gr field tips on. I think that should put them around 430 grs. It has a peep site but no kisser or string silencers yet. Anybody want to guess at what kind of speed I might expect with this setup. I doubt if I will be doing much shooting past 30 yds for quite a while. Black bear will be the first animal I hunt with my new bow and I tend to place my bait around 20 yds rom the stand.
