Sure do need a bigger target maybe a box car, was shooting a 6.5 PRC with 139 scenars, that's all I had loaded for it. think I will try my 300 Win mag in the morning before work, if there's not much wind. Rio7
The PRC/.697 BC melding,ala 147...is gonna be tough for a 300 Winny to hang with.
No thang to spot .243's at said distance.
