Varget works well on heavier bullets, slow velocities on light bullets.
H335, H322, 748, Benchmark. Highest velocity with extreme accuracy is with N133 with the 50's and N135 with the 55's.
On yotes, I shoot the 50g Sierra at 3600 and the 55g Sierra(N133) at 3500(N135). The 55g Sierra lead tip blitz at 3500 shoots a coffee can size hole in a yote, no nippers, runners, or spinners.
