108gr Lapua Scenar , Ramshot Tac

[Zeneffect]

Iirc the 108 being the same shape as the 123 but the weight is just set further back. I would try less jump if possible as you are probably pretty far off the lands. Get a bullet comparitor, or make your own to find out how far out you are. I recall not loading them anymore because the bearing surface was long amd there wasn't as much of a speed jump from lower weight. I still have a bunch of the 108s if anyone wants measurements.
