I would like to get a CZ527 in a 6mm. 6.5 Grendel or 224 Valkerie are much easier choices, but I want to be difficult. In short, 224 V isn't a legal deer cartridge in all states, and 6mm bullets of the same proportions of a 6.5mm will be 25% lighter and have the associated reduced recoil and faster velocity. Problem is I don't like to reload. I have done a little bit of it, and I just don't have the time for it right now. So of the available options (6mm PPC, AR, 40 Tubro, Fat Rat, Dasher, BR, etc) Are there any custom shops selling loaded ammo? I've seen some 6mm PPC, will that need a custom bolt? I don't think 243 WSSM is safe for the 527 and it is a little excessive in this context. If you had to guess what wildcat would hit the mainstream in the next 5 years, which would you guess? Ideally, it would be nice to chamber in the cartridge that factory ammo becomes available for. But second best would be to chamber in something that could be reamed to the factory version in the future. I feel like it would be silly for no one to release a 6mm to fill the void. And as a side note, I think an ultralight 527 chambered in it would be the ultimate mountain rifle, with minimal recoil even in a 5lb rifle. Also great for youths. With advanced powders and copper alloy bullets, it wouldn't be far behind the 243 win, possibly the most prolific youth cartridge. All in a gun 3oz lighter, 1/2" shorter, and faster cycling than short actions. Last question... Should I just stop being impatient and wait till one is released?
