Which chamber for a custom bolt gun?

[warped]

I was not trying to be rude, rather just pointing out that someone carried out the research and paid the bills so we could have what is now the Grendel, without such an expenditure there would not have been a standardized chamber.

I did not intend to be hurtful, my apologies if it was interpreted that way, this forum has been a great benefit to me and also to many others.

I am most appreciative both now and in the beginning when I did not even have something to contribute other than just my most humble experience.

Don't mind me, I am just an old NCO with some good friends who have truly paid the piper.
