OCW 6.5 Creedmoor. Where to go from here

[sig2009]

Working with 140gn eldm and H4350 and 140gn RDF and IMR 4350.

#4 and #7 look to be the best so far. Should I just play with seating depth on those two or are there any other ones that look to be promising?

2-4 are grouping close. I would work with #3 charge weight and play with seating depth to see if you can shrink the groups. You could mess with 5-7 also. It is my understanding that OCW is designed to allow for any minor variation in the charge to minimally impact the POI. That is why we use the charge in the middle. In case a bit more or less powder gets thrown.

Try the Berger 130 AR OTM Tactical Hybrids... they will help so you do not have to fight seating depth as much.
