OK, even with long throat the T-3 still shot MOA with factory Win 180 PSP. The COL for the factory was 0.200 off the lands which is rather large bullet jump in my way of thinking but it still performed so I guess it becomes so what? I forgot my 165 gr. loads so I couldn't try them out but will post up once I gete back to range. All in all, not bad first day out. If it shoots as well for the 165's I will be OK with the long throat.
