Just got in 250 6.5 Grendel cases yesterday, ordered direct from Starline last Monday. Grabbed 10 at random to check, all are +/- about .001" of trim to length, and all were exactly the same, base to datum, and also about .001" less than my fired brass. Looks like "prep" for this batch will consist of deburr and chamfer, may need to run a few through the sizing die if the case mouths are dinged up. Thought I'd ordered a case gauge for this cartridge, but can't find it, maybe it's still in a shopping cart somewhere . More later, once I actually start loading some.
