Help wanted 260 loads

[Suki]

Hi new to this site.

I am just about to take delivery of my Accuracy Internal AX in 260 cal.

The problems is I cannot get access to H4350 powder.

The rifle will have a 26" boarder barrel in a 1/8 twist.
Bullet I will be using is Berger VLD 140g target
Powders I have are.
N140
N150
N550
R15
Can you give me some loads with any of of the above powders, ( what fps should I be looking for not looking for a hot load )

N550 @ 38.3 grains from a 24 inch barrel will spit it out around 2530fps (top load is 40.3@2695 fps)
I have used RL15 @ 37.0 grains getting velocity of approximately 2640. This is not listed for a 140 grain bullet, but is listed for a 130.

36-37gr of Re-15

not sure about the other powders. Some guys use Varget too.
