You have a very good start with good componets like Lapua Brass.

May need a little work on the other stuff.

I prefer Match grade primers like Fed 210 Match or CCI Br2.

Powders prefer IMR 4895 or Reloader 15 with Fed 210 Match primers......Varget is also good with BR2 primers.

Excellent bullet the 168 BST.

with Varget @ 46.0

IMR 4895 @ 43.6 (Very Accurate) with FC 210 Match Primers (dupilcates Fed Gold Medal Match Load if you use FC brass and 168 Sierra MK bullet)

IMR 4064 @ 43.5 same as above
