For me, Varget seems happiest pushing 60 grainers and up in 223. 55 it's in the "crunchenticken" zone and depends on how it gets packed in the case and how deep the bullet needs to be seated.
Further, the kernels are pretty big for Varget and it's smart to trickle/tamp your charges, which is a pain I reserve only for special loads. Right now, my mass-charge load is 50 grain Hdy tips (zombie or red) over H4895. But I've done some other loads for friends with TAC and was impressed with how easy it was to work up, such nice flow, such consistent charges and really nice on paper, easy to get clover holes.
TAC to me is what H335 should be.
