Hello everyone! I'm thinking ahead a bit, but I'm considering a 6mm build in the next couple of years. I will preface this discussion with the fact that I will be building the rifle on a Remington 700 action in 243 Win. I have shot thousands of rounds out of this rifle, and it is my favorite gun. Period. I've killed prairie dogs, varmints, coyotes, deer, and antelope with it. Shot paper, steel, shotgun shell hulls, and coins with it. The thing has always been a tack driver, and I
it!
Anyway, my only complaint about the gun, being a factory rifle in 1-9.5 twist, is that I could not stabilize anything heavier than 95 gr pills out of it. Groing in the long range game, I've found myself leaving the gun in the cabinet in favor of my 7mm Rem mag and 308 Win.
I'm torn about what cartridge to focus on for a new build. All would have a 28 inch barrel with a 1-7" twist.
243
Pros - I already have a love for the chambering, I have the dies, brass, etc.
Cons - you cannot let the heavier bullets out as much (COL) as I might want to.
6CM
Pros - There are components, specifically brass, available. There is more room to seat bullets out in the short action mags.
Cons - I'd have to buy new brass and dies. I will also be honest that I don't want to become part of the CM fan Boyz
I like my older cartridges.
6 GT
Pros - From everything I've read, you get more for less. The same velocity, less powder, less recoil. The chambering looks exceptionally efficient! I can let my seating depth out even more than the CM.
Cons - finding brass looks to be a pain in the ***, and again I'd have to get new dies. It doesn't hurt my pride as much as becoming a fan boy, but switching still hurts my pride a bit.
Those are my thoughts. I'd love to hear what y'all think. Thanks in advance!
