Hastings,
28.0grs of 8208 ?
2517 fps in my 18".
SRB 118, AR Comp, Power Pro Varmint at around 28 grains if I remember correctly. I have a full jug of N133 that would probably work fine. The SRB 118 was made by AA for the Czechs in the 1990s. It gave the best accuracy. My load records are out in the shop but I believe all the loads were around 28 grains. Haven't shot it through the Crony but it seems to have about the same trajectory as most .308W 150 grain rounds at least out to 300yds.
