I have just commissioned a new 20 practical varminting rifle, the action is a Tikka T3 stainless and the stock is the T3 Super Varmint, the donor rifle was a .222rem lite. I an having a 26" Pac-Nor 11 twist Sendero barrel fitted chambered in 20 practical to enable me to use the .223 Lapua brass. I have purchased a set of Redding .223 competition dies and am surprised to find that Lee do not manufacture a 20 cal hand case trimmer !!!! Do you guys know anyone that makes a hand case trimmer for the 20cal similar to the Lee ones ??? Also, I could do with a bit of reloading advice, I am hoping to shoot the 39 grain Sierra BK's to benefit from the fantastic .287BC but am not sure which powder will give me the best results in this rifle. I have done a bit of research and am lead to believe that either Reloder 10x or Viht 133 is a good starting point for velocity/accuracy in 20 practical, is this about right ???? Your help and advice will be very gratefully received.
