I just got a new chassis - XLR Carbon - for my Tikka T3 .308 and I'm having an issue with vertical stringing that I never had before.
My load is:
Nosler Custom Comp 175gr
IMR 4064 42.7gr
Lapua brass
CCI 200 primers
The primers are a point of concern as I've only used GM210Ms but haven't been...
If anyone is looking for Lapua brass, 3rd Gen Shooting Supply just got some in. Great company to deal with too!!
