Do any of you reloaders have a good load for a .308 with 1 in 10 twist for long range? i'm looking for one that will be good at 500 and one for 1000

175 gr SMK
44 gr Varget
Lapua brass
CCI BR or Federal GM primer

That is a grain under Hodgdon maximum but is more than what Sierra shows.
I have been told that is because they use Federal brass which is softer than Winchester or Lapua.

2.835"

That is an .012" jump to the lands in MY rifle.

My load is very similar to Jim Watsons.

43 grains of Varget
175 Sierra MK
Federal brass (necks turned, trimmed, primer pockets trued, flash holes done)
CCI BR2 primer
C.O.A.L. .0010 to .0015 off the lands

On the 6mmbr website a national champion says his load is similar to this, but he found that brass and primer were not nearly as important as how far you seated the bullet from the lands. Seating depth is a matter of experimentation to see what your rifle likes.

Another load I have had good luck with:

150 grain Lapua lock base bullet (higher BC than the 165 Sierra MK)
44.5 grains of Reloader 15
CCI BR2, or Federal 210M
Lake City match brass, or Federal Brass. (all brass has been worked as above)
COAL: 2.815

OR:

168 Sierra MK
42.5 Reloader 15
CCI BR2 or Federal 210M
Federal Brass
COAL 2.815

I haven't found any significant difference between my Federal and the lake city brass. I even measured the water weight content and found it to be the same. That surprised me as I had always heard that LC is thicker with less volume capacity. Maybe this lot of LC brass is an oddity, in any case I would sure recommend checking your brass before interchanging such an important (and potentially dangerous) component.
