I've not yet run the Berger in my 260 Rem. I have in my 6.5x47 Lapua and it's a very accurate bullet. The powders that have worked quite well in my 260 Rem and other 140's have been Rel 19, H4350, H4831sc and H1000.
Good luck on your quest.

Originally posted by Dans40XC: Of the powders that you have listed H4831 is your ONLY powder option to load in the 260Rem case.
H4198 & H380 are fast burn rate rifle powders.
V-V N110 is a slow burn rate 357/41/44mag pistol powder.
I have to agree. The 360 running full speed is slightly overbore. Powders in the H4350 & slower range seem to give the best results. I run 7828ssc, H4831sc, H4350 in my 260ai under 140-142gr bullets with terrific accuracy & top vel.
