barrel length ? for 243 ar-10

[ssmlr3]

I have a DPMS 338 federal(.58" groups at 100yds) i get to keep. i am having to down size on number of guns due to divorce. thinking of going to a 243 cal upper to compliment the 338 fed. Is 243 critical for a barrel length? want something for pronhorns coyotes etc. ammo not $. easy to get. this would give me a broad range of hunting ability with one gun bag to carry.

.243's like long barrels. Say 24" minimum for your set up. Just my $.02, but sure others will agree

24 to 26 will get you to 1000 easily, with the heavies like 115 gr, a good barrel in 1-7.5 or 1-8 twist is the ticket.

I see the .243 as being more like a Varmint chambering than, say, a Bear chambering. I see it being happier with a Varmint-type barrel; say, a longer one.

ok the dpms lower from the dpms lr 338 federal lite must have dpms upper..does the lower always go to the lite UPPER? or can I put on the 20" heavy upper if so how heavy is it? thye make the upper 243 in both 18" barrel lite or a 20" hwVY/ WITH A 18" 243 WHAT WILL IT DO PERFORAMCE WISE? HOW MUCH LOSE IN SPEED ETC?

Gas gun barrel lengths must be matched with gas port location and size. I'd be careful about customizing the length of your 243 AR barrel unless you are dealing with a company or smith that know what they are doing. Otherwise, you may become a frustrated owner. That said, 24 or 26 inch would probably be the best choices. Standard lengths and more appropriate for a "mini-magnum" which is what a 243 really is.

I am running a 20" 8 twist on my dpms, getting good accuracy with 87vmax and 105 amax.
