So, I don't really have anything for sale, but I'm wondering about the cheapest way to get an action. What would the following stuff normally bring?

Barrels:
7-08, matte, 20" off youth gun
7-08, matte, 22" off regular gun
.243, matte, 20" off youth gun
.243, matte, 20" off regular gun
.308, matte, 26" heavy
.308, matte, 20" heavy
.308, matte, 20" heavy threaded
.22-250, matte, 26" heavy

Stocks
SPS youth, Short action
SPS standard, short action
sps varmint, short action
Hogue overmoulded, black
hogue overmoulded, gray

So, here's the story: I can get a

.22-250 SPS Varmint for X dollars
.308 SPS Varmint for X+$50
.243, 7-08 either youth or full size for X+$75
.308 Tatical (hogue, 20") for X+100
.308 Tatical threaded for X+$125

I'm trying to figure out which will let me sell parts and come up with the cheapest action. Obviously, the .22-250 is cheapest, but with the least desirable barrel and stock?

Thanks in advance,
Adrian
