    So lets say you've got several .308's in all sorts of configurations & just finished a .260 Rem. You have all the components for x1 more except for the barrel. What would be a fun cal. to make. You have no utilitarian need for this rifle, just a play thing to do on a whim.... You enjoy shooting between 100-500 yd but don't need anything specific for any distance... & You reload your own ammo

    .22-250, .220, .243, 6mm Rem, .257, 6.5x284, creedomore, .284, 7mm/08, .338 etc. etc.

    (The last project .260 Rem)

    Already have .308 and .260 then I would go bigger. .338 federal or similar.

    I'd go .22-250 or .243. Can't really justify either except for saying both cartridges interest me and always have. I'd lean toward .243, personally.

    I like the 6.5 creedmoor but would want to stretch it out past 500 yards.

    .243! Easy choice for me. Ammo is still relatively cheap, it would be great for long-range work, more power than .223, not as much recoil as .308, etc.

    I will be watching with interest since I have 10 Pmags ordered from the "Airlift" and presently don't have an AR of the larger variety.

    MErl,

    did you mean .284 Win. ? For what reason would you choose the round you suggested?

    MErl,

    Thanks for your post. I never heard of the .358 and should have done a better search before responding so fast. I understand that it is a heavy bullet / round, short range intended. I'll search further on its brass and bullets, but great suggestion! I'll have to see if a barrel for this can be crafted and how the cartridge fits in the mag / feed through a gas gun.

    Great to learn about an obscure cartridge!!! That is why I made this post w/ ?'s

    .243 seems like a nice caliber to have on hand. I dont have one but have read and heard nothing but good stuff. from varmints to Black Bear in a pinch. Only other would be a .270.
    will a 270 work with am AR10?

    No, a .270 is a necked down 30/06 with a longer bolt throw than a .308 'OAL' cartridge length 'tip to tail' which would not work in an AR-10. Great round though, I have them in Browning A-bolts & they are generally my 'go to guns' come Nov.

    Come to think about it, has a .270 WSM ever worked in an AR-10?.... Worked well...? I know that the mag would fit a few less rounds but the feed angle etc.???

    Oh right, right 308 OAL. I didn't even know a 270 wsm was out there. what about a 300 WSM? that would be fun too in a AR!

    dvdcrr,

    ? as in the Remington version or in a 6mm version like the .243? Surprisingly the 6mm Rem brass has not sold at my local dealer, might be an easy thing to reload for.

    I have no opinion.

    I can't lift or carry a 10+ pound with glass & sling AR-10 like the one pictured from the truck to the bench anymore.

    I"d go for the .243, but I'm fond of the caliber. Also an advantage is it should be able to use the normal AR10 mags. Right?

    6mm rem is tapered and should be smooth feeding and reliable. I'd go for a 1/9.5 twist. Or 1/9.
