I know some guys are up at 2875fps.
I'm closer to 2775fps.

Re: 260 FPS
I run my 260 with 142 with different loads, a hot one (for me) at 2850 for 800+ yds and a lighter load around 2700 for 600 and less.

Re: 260 FPS
We're running 140 weight bullets at 2820fps with a 28" barrel, could do a lot faster but when it's making wee itty bitty holes and hitting small steel at 1000 yards no sense in pushing faster which is harder on everything. Just a couple clicks more to get there but lots longer barrel life. My short barreled (15") XP is only getting 2500fps and it gets there just fine also but also needs just a few more click to do it. Velocity isn't what hits small steel at long distances and the wind is going to move every bullet around to some degree. Get good accuracy in the 2800fps range and learn to decipher wind and you'll be good to go.
Seems that 2800fps for the 139 to 142 weight bullets is like magic in the 260 even for very long steel.

Re: 260 FPS
So, are the velocities mentioned in this thread for a 24" or 26" barrel, or does the extra couple of inches nor really matter? Also, does running a lighter bullet at 3KFPS work better at 1000 yards and is it harder on the barrel?
I'm in the planning stages for a future .260 build.

Re: 260 FPS
friend's 20" 260dpms is 2650 with 140 amax and hits at 1k. I think his 123 grain load is just under 2800 and it works too. Will ask him about his load but I'm almost positive it is 43.5 grains h4350 for 140 and 45 for 123.

Re: 260 FPS
Using 42.5gr of H4350 in all four of our guns. All of them also liked 44gr of H4350 but that was too hot in a friends 260 so I'd venture there carefully.

Re: 260 FPS
I'm worked up to 43.5 with the 142 SMK and was getting 2880 last time out.

at 42.8 im at 2933fps.. but accuracy was meh!... 42.5 accuracy much better.. but need to re crono..

Re: 260 FPS
i run mine at 2750 w/ sceners 139 gr 24" barrel
at 28" they ran at 2850
i think 2750 is fine... until you can master the wind in .1 mil
increments going faster is pointless

Re: 260 FPS
26" at 2850 with RE17. Went to 2915 with no signs of pressure, but accuracy wasn't as good.

Re: 260 FPS
Dude, 2650 fps, especially out of a gas gun and easy on the brass. 27.5 mins out to 1,000 yds. just like my 220 MK's/.300 WM at 2630 fps. This has been my experience. Accuracy, you would'nt want to stick your head out at 1,000 yds cause it will most likely come off.
