Reloder 19 is a long time 'favorite'.

210 Nosler Partition. I tried RL19 first, wouldnt go over 2850 no matter how much powder I put to it. I'm running 2950 with the IMR 4350 and 215 primer in a Sako L61. My nephews 338 same bullet, powder and charge weight but I have to use a CCI250 primer in his Ruger.

Try RL16 and/or 100V. In my 338s, 100V is smoking fast with low pressure. I like RL16 for the speed but also temp stability you don't get with the other powders mentioned.
