N560, 6.5 prc and 156 Bergers

[Squatch]

Hey guys, looking for some guidance. I have a good supply of N560 and would like to work up a back up load using thec156 bergers in my 6.5prc. Any data you can share is greatly appreciated.
Currently I have a good load using 56gr of RL26, but with as scarce as it is I am looking for a good alternative load using a powder I have a good supply of. TIA

My 6.5 PRC go to load right now is w/ N560. 24" 8T 5R Bartlein in #4 contour . Brass is new Gunwerks(ADG?), COAL is 3.001 @ 0.025 off, 54.5g of N560, 215M primer, 156E. Pretty sure I can still load up to the next node but range was about to close and I haven't made it back. Please work up to this. Also did not have time to chrono but should be around 2900 MV. 6" target @ 200 yds.
