Which 6mm don't need to be fireformed?

[fvalmostthere]

Currently have a 6.5 creedmoor setup with a factory barrel. With about 1000 rounds on it I am starting to look into an aftermarket barrel. I'm a little torn between staying with 6.5cm or going to 6mm. I don't really want to deal with fireforming even though I do reload. Which 6mm should I look at? Or just stay 6.5cm?

I am currently running 123 scenars around 3050, reading up on 6mm seems like a lot of people are running 115dtacs, whould there even be a noticeable recoil reduction?

Thanks!

6mm creedmoor and .243 both have plenty of factory brass options.

Do you mean foreforming as in form a parent case to a new case?

Just stick with the 6 creed. Or you could do 6BR, 6x47 Lapua, 6xc, 6 SLR, or .243 win.

Edit: Almost forgot the 6mm Gay Tiger...that’s always an option.
