Having my build started by SAC. Plan on using the rifle for 1000 yard competition eventually. I chose a 26" Bartlien barrel. Will I be happy with this length? Going to run 140 Berger Hybrids. Should I stick with this length or should I go longer ?
I don't think you need any longer.
You should be just fine with a 26.
26" is plenty of barrel.
UYeah you are good, the 140 Hybrids will be humming quite well at 1000 out of a 26" barrel, you could even go 24" without any ill effects.

You won't be disappointed. I shot my SAC built .260 (24" Krieger) for the first time a few weeks ago and was hitting 1150 no problem.
Every barrel is different but I would think 2750-2800
My DTA 26" 260'barrel shoots Berger 140gr BT and VDLs at 2710 with Lapua brass and 45.7gr H4831. 0.16 MOA at 100 yards. I think you'll find it to be perfect for your needs!
Go shorter. I have a 20 inch truck axle on my 260 and it shoots darts.
Oh and I'm shooting the 140s as well.
I have reached 1250yds easily with a lesser quality build and only 24 inch barrel, you'll be fine with what you have.
cheers.
cheers.
Any signs of high pressure? That's a pretty hot load.
Nope, told Mark and he said some barrels are faster than others. I could try to push it to 3000fps but barrel and brass longevity would be drastically shortened.
Nice
26" or 24" in either 1:8 or 1:8.5 is a good length for the 6.5's I have DTA SAC Bartlien 26" CM pushing 2830 my 260 DTA Lother 26" pushes 2970 and my 24" 260 Kreiger pushes 2850 all using 139-140's 4350 and 4831SC. You will be very happy with Marks work for sure!
