WHAT cal. AR-10 BUILD WOULD YOU DO?

[VTmtn.man]

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.

 

[mnhntr]

Nice rifle by the way. I love the .260

 

[Bobson]

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.

.243

 

[JustinJ]

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

 

[The_Armed_Therapist]

.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.

[VTmtn.man]

MErl,

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

 

[VTmtn.man]

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

 

[lobo9er]

.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?

.243

 

[VTmtn.man]

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.

 

[VTmtn.man]

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.???

 

[lobo9er]

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!

6MM

 

[chaser_2332]

6mm creedmoor hands down

 

[VTmtn.man]

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.

 

[dvdcrr]

I was thinking 6mm REM

 

[rcmodel]

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.

[Mamertine]

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?

 

[dvdcrr]

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