Assuming all your loading steps & parameters are done correctly, I'm past the point of wasting a lot of time on finicky rifles.................it will have to be something very, very special in order to make me want to keep it if it is.
Over the years, I now want a rifle that's not very finicky & will generally shoot most (good) bullets & powder combinations well.
I generally start load work with NBT's, as in most calibers & weights, they generally are reliable for beginning load testing.
YMMV
