I had great luck with N-160 in Lapua brass with moly'd 87 V-Max in a 1-10 Broughton barreled rifle giving me 3620 fps & good accuracy. This was a balls to the wall load & the primer pockets started giving up after about 5 loadings, but it sure did shoot well. I would think you could do better than 3500 very safely with 85 grain +/- bullets.
