Too Many 6mm\'s To Choose From As I was preparing for the spring varmint shoots, I was shocked to realize that I have no 6mm's in the gun safe. So was my local gunsmith. To fill the gap between the .220 Swift and the 6.5x55 Improved, we both agreed I need a 6mm. Unfortunately, I can't figure out WHICH 6mm to have him build. Primarily to be used for 600-1200 yard p-dogs, when the wind shuts down the .220 Swift with its 40 grain bullets, but I wouldn't mind something that can be used on antelope with a stronger bullet if I ever draw a tag. Looking at the options, it seems I have: 6mm PPC: OK, it's accurate, but there's not much oomph,is there? 6mm BR Remington: is this gone, or just hiding? 6mm Norma BR: factory loaded, if you can ever find it, and good write-ups from those paid to write. Maybe the best so far? .243 WSSM: factory loaded, but not very good brass for handloading, not yet, or so I'm told. 6mm Remington: Still seems the velocity king, and I think I can use a .30-06 action. Factory loaded, but not well, it seems. 6mm-06: Certainly not a trendy shape. 6mm-284: Seems about the same as the 6mm Norma BR? So, that's what I get from reading. What's the word from the real world. Which should I go with?
