Over the weekend I cleaned 700+ cases. Amongst these are about 600 7.62 x 39 brass. I intend to convert some of these to 6.5 Grendel brass.
In the mix I have about 250 Remington small primer cases and the rest a mixed bag of large primer cases with many headstamps. Most being IMI and Yugoslavian. A few Lapua and Winchester too.
I already have a few genuine factory 6.5 cases from PPU that are large primer.
Now usually I'm not the kinda guy that gets sweaty over primer sizes. However I see a lot of "disCUSSion" in some of the forums about the differences between the two primer sizes when creating your loads for the Grendel.
I'm thinking to use the large primer brass as it's the same as the few real Grendel cases I have. Also the small primer 7.62 Russkie is sought after by the folks that hand load for their bolt guns.
So am I off base here with my decision to use the large primer cases? If so, what is wrong with my thinking?
