My BDL SS shoots the 180gr Partitions best using 94.5gr of RL25. Three shot groups stay between 1 and 3/4 MOA.

My own guns prefer 95gr to 96gr of r-25 with 180gr bullets.

I don't shoot 165 bullets in my 300 RUM (I use my 30-06 for the 165 grain pellets). I use 80 grains of IMR 4350 with the Nosler Ballistic Tips or the Partitions. The muzzle velocity of the Bal. Tips is 2980 FPS. I use Fed 215 mag primers with an OAL of 3.6".
