I've tried 3 different BH's and they all group well and in the same place. Shuttle T's, Wasp bullets, and Slick Tricks. But with all 3 of the different BH's, I'm still not bringing my FP and BH groups together. Closest I can get is about 4 inches at 20 yards. That translates into 3 feet at 70 yards roughly. Vertically, I'm the same, but off on the horizontal. Shooting tight groups, no fliers or anything, just not hitting with my FP.
Sounds like the spine seam is not on the bottom
One thing to keep in mind that it doesn't always work, one of the reasons that mechanical broadheads are so popular.
Having said that, I shot my bear mauler today with an old style broadhead and it grouped with the field points @ 30 yards without any adjustment. A bit low at 50 yards but still ok. The broadhead was 125 grains and the field point was only 100 grains. Yep makes perfect sense hey! :confused:
Nah they're called 'Tusker Spirits' and there very popular here. Nice and cheap and hold a good edge, look old timey though.
Son of a ....... I couldn't just leave it alone. Tore the bow down and started retuning. Paper tuned, and the arrow is so far inside that's it's ridiculous. Shooting bullet holes, but the arrow is at a very visible angle across the riser window. Front of the arrow is straight above the inside of the grip. So now I'm gonna scrap that, and go to vertical and horizontal tuning, then do my walkback tuning. Thank God I have until Oct. lol
Here is a tip from Sonny T

Before setting center shot! Back off the SOS, STS or whatever they call them. Don't even have them close to the string.
Had a bow come that wasn't flying arrows right. So I took a look, fired a shot, and sure enough something wasn't right. Looked at center shot and it didn't look right. The guy said he had just set it. So I noted the bow string right on the SOS and off center on SOS. So I moved the SOS forward and took another look at center shot. It was different, still not right, but different than it was before. So I set center shot. I then moved the SOS within about .040" of the string and I also center the SOS to the center. Took two shots to hit the bull's a little better and a couple more to refine the sight to hit the X. Customer was happy.
So evidently the owner had set center shot with the SOS pushing the string slightly off center. Too dang hot I closed the shop at 1:00 pm
Thanks Hutch, I'll give it a try. This FC400 is making me feel like I've never tuned a bow before.
