I was just curious what anybody is getting for velocity out of there AR in 260? any bullet weight or barrel length? I just ran mine through the chrono today with the 120 amax 24in barrel 43gr of reloader 19 and were running about 2750 average.
not a .260 but a 6.5 creedmoor(close)getting 2650 out of a 20" noveske barrel with factory hornady 140 amax.getting ready to start reloading for this cartridge

Have you had any problems with feeding from mags? I mentioned building a creedmoor to a know it all gun store employee and he was certain that these rounds don't feed properly from mags because the case wall is more straight than a .260/.308.
Sorry to thread-jack, didn't want to start a new thread for a quick question.
6.5 creedmoor works great in a gas gun. I just got a gap10 with 20 inch barrel chambered in 6.5 cm. I have fired about 300 rounds and had one failure to feed only because I had adjusted the gas block to much. Backed out the screw a little and it runs great.
GAP are also making their GAP10 in 6mm Creedmoor, and I have one on order with them in 6XC. I think the general consensus now is the CM (either 6.5 or 6) is the preferred way to go over the 260 and 243 from a AR10/LR308 due to the longer higher BC bullets that can be loaded to mag length.
I have a bare stock DPMS 20" in 260, I switch my loads from my 260 bolt gun to the gas gun I loose about 100 to 150 fps. Of course my bolt gun has a 25" barrel. But the accuracy is pretty good for stock, 3/4 moa usually. I usually shoot 142 SMK or 140 Amax, but the 123SMK shoot good also.

Sorry to thread-jack, didn't want to start a new thread for a quick question. </div></div>not had a single problem out of my armalite sass 6.5 creedmoor.everyround has fed,every round has went boom.to me the creedmoor is the ideal gas gun round.
I am looking into either the .260, or 6.5CM barrel for my MWS. However, with a 20" barrel niether of these calibers seem to be moving crazy fast.
Do these slower speeds still give an advantage to gas gun users in windage and drop? I am shooting a 16" .308 now so I am sure I will see a vast improvement with a 20" 6.5mm offering, but what about when compared to a 20" .308 instead of my current short barrel?
