I’ve got an extra contender frame looking to purchase another barrel.
Already have.
7-30 waters
357 max
Had a 30 herrett wasn’t to exciting for me.
Think maybe 204 ruger,223,maybe 6.5tcu 6tcu. Looking for some opinions. Could be pistol or rifle form.
Geesh… can’t make a bad choice there.

What are you going to use it for?

I love the small 6mm barrels. I have 2 6tcu, a 6/.223, and a 6x47. They can serve many purposes from targets to varmint/predators. You can even take deer with one if you take everything into account.
The 223 is a great barrel also. My factory 14” barrel has 1:12” twist and shoots great with a 40gr bullet. But if you have a fast twist barrel made, you could shoot the heavier bullets and become even more versatile and add more uses.

Something based on the 223 case is a bonus choice for brass availability etc. whether its the 223 itself, or one of the small 6mm and tcu etc.
its all good. You cant lose.
Ernie i made my 6x47 cases from 204, but it pushes the shoulder back a bit. A direct neck up from 204 to 6mm would have a little more capacity.
Reeders 240 raptor necks up the 204 to 6mm, and then im thinkin( by memory) fireforms to improved shape like a tcu.
