Don't know if this is the right place for this post ,if it is not feel free to place it where it belongs.Posted a thread about a guy giving me a bunch of brass and projectiles.Was just wondering. Got some doner actions.One I am considering is a rem model 788 in .308.Thinking about making a bull about 26 or 27 inches.Probally with a Richards micro fit stock.Question is should I go with the .243 or do something different like chambering it in 6mm rem ,blowing the neck and making it a 6mm A.I.Would I gain enough to make it worth while?Should I think of a different parent case ? Kinda want to keep the short action but don't have to. Been wanting a hot rod 6mm.Any sugestions(RIDGE) anybody.Nothing concrete yet just sorting out ideas.Thanks guy's.............Alton

I too like the 6mm's. Dad shoots a 788 in 6mm, My brother and I both have savages in .243 and then came along my jewel. Remington 721 action with a 28" montana rifle barrel, boyds jrs stock and timney trigger chambered in 6mm-06. I bought it second hand, so I don't know all the chamber specs, but it came with redding dies and it will shoot. I use a mixture of 6mm, 6-284, 25-06 and .240 weatherby data for a starting point and reference. I've never had a gun shoot so accurate with different loads without changing poi. IMR4831 is become my powder of choice in it. Altough h414 isn't bad with the 65 gr vmax and 68 gr bergers.

The 6mm Remington would be interesting, but I would suggest a 1:10 twist as opposed to the standard 1:9 to allow for stabilizing the heavier bullets.

A 1:9 twist will stabilize heavier bullets than a 1:10.

You know, I've read his post reply about 6 times now, and I'm still not sure which way it was meant to read..........Not yours, Keyshunter...

Sorry to tell you this but your wrong. The slower twist does better at stabilizing heavier bullets. Talk to the smith and see what he recommends.

Not true.
This is the reason the 6mm failed, it was first designed as the .244 with a 1-12 twist which did poorly stabalizing the 100 gr bullets. Later remington re introduced the 6mm, in a 1 -9 twist, but it was to late, nobody paid attention, the .243 was on its way.

I thought the 6mm wouldnt chamber as a short cartridge, unless you seat very deep losing any benefit from the bigger case.
And if I were building a hot rod 6mil I would do a 1-8 twist to stabalize the 105 to 115 gr bullets, those have monster BC numbers

ZRE..your correct !! The fastest the twist the heavier the bullet in any and all calibers and cartridges !! Any gunsmith who reccomended or told anyone the opposite should stay away from your rifles..he doesn't have the oars in the water....As the range master for the Mifflin Co Long Range Groundhog match I get to see just about everything ever made sitting at the line, from right off the shelf to some of the best long range shooters on the planet... the 6mm/.243 is by far the most popular without question but in the 6BR remington and the 6PPC and why more non-competition shooters don't used them has always puzzled me, they are simple to reload for and some variations of both are factory available these days..their accuaracy is amazing compared to both listed above..they are just as fast and both will shoot 1 inch or better groups at 500 yards, even the common guy with a good one will shoot 2 inches or better at 500 yards... you guys need to look at both of these cartridges, they are amazing!! PLUS, there's a ton of other wildcats that are just as amazing..
