Which 6mm in long action Remington 700? Quality Brass is issue...

OK, I have posted way too many threads about my project, but each one brings me closer. The last post from a month or two ago brought me to the conclusion that my stable of rifles needs a 6mm of some sort.

Donor: Older 25-06 Rem 700 BDL that my dad gave me, but shoots poor.

I have a couple 6.5x55, a nice 7mm RSAUM, and I intend to invest in a 338 gun for big animals, in tough conditions, but for that, a "plastic stock and stainless" seems more appropriate....

I'd like a 6mm, and I am willing to fireform. But all the hassle of neck turning and messing with lesser quality brass is annoying.... I'd like something that starts with Lapua brass...

6mm Rem AI, or 6mm Crusader (same thing, basically) offers all I want in a LA 700. But no quality brass, except via complicated resizing from 7x57 mauser.

Am I overlooking some other option to get to 6mm using quality brass that will perform well?

I could just go with .243 Win. Great Lapua brass. But does not really use the LA at all, and has a reputation for burning barrels....

Perhaps .243 AI? Great parent brass, and to heck with barrel life...

I should say -- this is not likely to be a high volume gun, so barrel life is not a huge issue. Perhaps then, I have answered my own question. Just go with the standard .243 Win.

Someday my grandson who doesn't reload will be able to pick up a box of .243 for sure and shoot the old girl.....

Other options?

there's nothing complicated about it if you can FL resize a case you can do that

This is a no brainer, 6-284. Take Lapua 6.5-284 brass and resize it in the 6-284 full length die that will come with your die set and you are done. The 6-284 case has a pretty decent jump in case capacity over the 243 or 243ai and is nearly identical to the 06 case.

Using a long action, like you're doing, is the better way to go, especially if you want to shoot the 105's. Make sure you get a barrel with enough twist if you plan on shooting the heavy for caliber bullets, like the Berger 105.

I agree with that part of his answer. But for ease of fire forming, the .243AI is simple. Just take a standard .243 Win case (Lapua brass), load it up so that bullet touches lands, and touch it off in your AI chamber. Instant fireforming, and a great round. For heavy bullets, use 7.5 or 8 twist barrel.

I should have mentioned -- I'd like it to be a gun with a factory cartridge as an option, even if its a AI, at least someone can shoot the gun down the road if they are not a handloader. The gun was gift from my father and as such, should not leave the family. Its hard to know who will handload down the road 30 years.....

Then why not just keep it simple and build 6mm-06.
