Once in a while a bullet that shoots well in every other gun will not shoot in a certain one. Then you go back and try it again and it shoots quite well. This means that something else was changed in the testing.
I always check my action screws on non pillar bedding before going to the range for instance.
I would try the BT's again before giving up on wanting Accubonds. I find that they shoot the same by the way and with the same seating die setting as well.
