My rifle prefers Varget to H4895 for the 150 TTSX or etip. I was able to reach 2900 with H4895 but but was better accuracy. I shot my elk a weeks back with a 150 etip using Varget and a 308. Worked great.

I wouldn't do 0.2 gr increments. 0.5 is plenty fine enough.

Adversity doesn't build character, it reveals it.
