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.

Are these lapped before chamber or sans to save money? My first PBB prefit from the 6cm group buy, is a bit rough(un-lapped).

$487 for a Tikka Hybrid Lite contour threaded 5/8 x 24.
SPECIFICATIONS
Cartridge: 22 arc
Throat: .131” FB saami
Length 18" or 20"
Twist: 7 219 bore barrels

These are unlapped, the masses didn’t add it in…

I have got good results on paper and steel about the same whether lapped or not. I don’t clean frequently, and let barrels do their thing.

I also pull the barrel to clean with a cordless drill... So it’s easy for me and indistinguishable to me.

If someone want a lapped barrel, I can do one offs for a Preferred Barrel and give discounts they don’t. I can’t give the huge discount though.
