Which chamber for a custom bolt gun?

[adamjp]

I apologize for being rude in my previous post. It's just frustrating when you ask a question about something specific (which chamber for a 6.5 Grendel bolt gun) and you get no real answer, but there are three pages of replies from people telling you why something else is better. It's not just here, it's any gun board.

I am building a CZ 527 in 6.5 Grendel. The CZ is a shorter-than-short-action. It is designed for the .223 length rounds (basically anything that fits in an AR mag). It won't work with 6.5 Creedmoor/6.5x47/.260 as they are too long. It's the perfect platform for a light(er), handy Grendel rifle. I just want to squeeze the most accuracy out of it that I can, hence my original question.

I still haven't decided on a chamber. I sent out another CZ 527 to be rebarreled for 300 Blackout to keep me occupied while I decided on what to do with the Grendel build.

I'm doing the same thing but with a little Zastava action (aka Charles Daly Mini Mauser, aka Remington 799).

PTG advised me that the 6.5 BPC would be the best way to go with a bolt gun.
