I was wondering if anyone has tried this mold from NOE 266-140-FN-BY2 5 Cavity GC. I know people can get results with a cast 30-06 and 308. The 266-140-FN-BY2-81 is a 5 Cavity Aluminum mold. This mold drops a .266 caliber Gas Check 140 grain bullet with a Flat nose profile type. Designed for use in 6.5 Creedmoor 6.5 x55 and 264 Winchester.

I have used it successfully with my Savage bolt action. Both GC and non GC; using the load data from NOE I was able to get 1525 fps with a SD of 8.26 using Unique powder. Mind you, I was getting sub moa groups at 200 yards; I mainly use it for practice, but I bet with a different powder higher speeds should be attainable.
