December $487 prefit group buy, several barrels are a go

[WyoKid]

I am the odd ball since they don't make a prefit for:

Winchester 70 threaded 5/8 x 24.
SPECIFICATIONS
Cartridge .270 Win
Throat SAMMI
Length 22
Twist 7

Just ordered 6UM 30. Have a Tikka 300 win mag gathering dust. Would that work as a donor action for the 6UM? Thinking about jumping on the Rokstok train. What barrel channel should I order? Sorry about all the questions, but I don’t know what I don’t know. Pretty new stuff to me.

I’ll get the 223ai barrel ordered sometime tonight . Excited to try 223ai.

I’m kind of a barrel snob, this with be my first PBB, hopefully I get a good one.

I am somewhat interested in a 6 mag.

Can anyone explain the differences between the 6um and 6 prc (nsi)? I understand the parent cases are 7 saum and 6.5 prc, respectively. Is that accurate?

Case capacity?
Brass availability?
Dies available?

Why choose one over the other? Any insight would be much appreciated.

@NSI and I chose 6 PRC as the easy choice for brass availability long term and availability of bushing dies for an easy one step forming.

I’m in for 22gt.

2 now in for 22 GT?

I can do one offs, and give you a discount off Preferred’s price if you want. But the control round feed need gunsmithing.
