Spanky's is correct. I have never had a FTF but I couldn't get mine to group better than 2.5 inches or so with factory ammo. On the FTF's, did you notice if they where light primer strikes ? Did the FTF rounds fire on a second try? I relieved the tension from the forearm (floated the barrel, nylon O-ring x2, also sanded the rear of the forearm). Once I sanded the rear of the forearm to the point that now when I release the breech lock it falls open freely, that really helped with accuracy. My rifle likes the Federal 220gr TBBC factory loads shooting easily under an inch when I do my part. Also, my handi has gotten better the more I have shot it. Minor differences in the 35W neck size with ammo manufactures could definately lead to FTF's. Where are you located, I hunt in Mississippi and live in Louisiana and would be glad to help you figure in out. I was frustrated with mine to at one point, it took a little tinkering and figuring out what the rifle needed. I killed my first doe with it a couple weeks ago at 197 steps and wouldn't hesitate to shoot 300y with it.
