I have a few hundred of the Sig 277 fury hybrid cases I bought for a screaming deal a while back. Trying to figure out what to do with em. Necked down/unfired case capacity is 56.2gr, lapua 6mm creed is 51.8 according to my scale. Coal is pretty long with the 112 match burner, 2.980 the 109 eldm is 2.950, there is still a bit of bearing surface above the neck, freebore needed will be around 0.175. These would run perfectly from Tikka M+ mags. Performance should be directly in line with a 243 ackley, as these hybrid case heads handle a lot of pressure in testing. I might have a reamer made and toy with it over winter. Anyways, let me know what you think, or if you've played with a similar capacity 6mm! Largest 6mm I've loaded for thus far on standard bolt face has been the creed, however I do have a 6saum and 6prc being built.
