I recommend the 308 but with a 26" barrel and at least a 11 twist if not a 10 twist. This will let you get the heavier bullets with high BCs up to a good speed. With the right powder you can see 2550 to 2650'sec with the 208 Amax in a 26" barrel. This is a 700 yard deer hammer with the windage of a 260 rem. more recoil but more down range energy.
DEER HAMMER thats good to hear! Whats the right powder? Varget seems to get alot of use in the 155-175 range.
Search 7mm GT on here! It takes some time to from brass, but with 60.7 grains of H4831sc and a 29" barrel, and 180 gr Bergers I am getting a "validated" 3010 fps. and have never shot a group over 1 MOA with any load.
It willl consistently shoot .5 MOA with fairly regular .4 and .3 groups, at 300 yds. I would even let you use my reamer. I really want to see someone else build one but all of my buddies are being cheapskates!
My rifle weighs in around 13# and kicks like a kitten, could be the weight, but even in a lighter rifle it shouldn't be bad. There are also some new 6.5 ideas on here lately that are looking pretty good, 6.5ss and some others as well. If you want a wildcat.
Sounds like a very interesting journey you had, i read the thread where you brainstormed the 7mm saum wildcat. However it sounds a bit more involved than i want to go with on a rifle i plan on shooting a very high volume of rounds from.
