I just load to factory COL with the 257 Rbts. I have several in that cartridge and don't want to load different lengths for different rifles. Here's the first 3-shot 100 Yd group with 75 Gr. VMax. Rifle was straight out of the box. 80 Gr. TTSX shoots to same POI.
Nice!
I'd smile with that performance.
Shot a 3-shot .2" group and quit there. Haven't shot for groups since.....just one shot every season to check zero.
I was definitely smiling.
