SAC 260 Build

[408s10]

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 ?

 

[dworrel]

I don't think you need any longer.

 

[PatrickChewing]

You should be just fine with a 26.

 

[rubicon_unlimited]

26" is plenty of barrel.

 

[408s10]

Sounds great! Just wanted to make sure I made the right decision!

 

[Pusher591]

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.

 

[408s10]

What FPS could I see with 140's with IMR 4350?

 

[bmmc]

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.

 

[408s10]

I think I may have heard about your gun from Mark. I am very excited to receive my gun!!

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!

 

[TwentyFiveTwenty]

Go shorter. I have a 20 inch truck axle on my 260 and it shoots darts.

 

[TwentyFiveTwenty]

Oh and I'm shooting the 140s as well.

 

[leadbullet]

I have reached 1250yds easily with a lesser quality build and only 24 inch barrel, you'll be fine with what you have.
cheers.

My DTA with SAC built 28" Bartlein 8-Twist is pushing 140gr A-Max 2950fps with 45grs of H4350 near sea level.

 

[408s10]

I guess we will have to see what my 26" barrel will push these Bergers!! And I found 10 pounds of 4350 today soooo I am set!!

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!
