My question is about the faster shooting bows and mechanical type broadheads. I was thinking I would use a mechanical type broadhead with my faster bow but I keep reading on some forums that the heads seem to open up in flight at these faster speeds like in excess of 290 fps. The broadheads I'm referring to are both front swinging and rear opening style heads and don't use a locking rubber band to hold them closed.
What's the concensus here? Do you think if I use this combo that it creates a problem for good flight problems. I get great flight now using a fixed blade broadhead. A 450 grain arrow at those speeds should get great penetration with any broadhead but my concern then is accuracy.
If you are getting good flight with a fixed broadhead at speeds over 280fps you are doing real real well.
Good fletching makes an enormonous difference stabilizing broadhead tipped arrows. Blazers and FOBs help. The only issue I have with FOBs is they sit so far back on the arrow shaft they get pinched on short axle to axle bows unless you open up the string loop. I don't like to do that but if I was 100% committed to FOBs I would.
I square the insert end and nock end with G5s ASD. I also strive for as close to 12% FOC as possible with carbon arrows. IME, carbon arrows need much more FOC than Aluminum. That's why I shoot 125grain heads on my arrows. My total arrow weight is 455grs with the 125grain head and they fly at 285fps.
I get plenty of penetration with this setup shooting Rocket Aeroheads Stricknines. These are rubber band heads and I like them.
