I have a Cooper Varmint Extreme (check out page 5 on this section half way down for several photos) N120 powder, Winchester brass and primers, 20 grn V-max are the bomb for this round, for around 3750 fps. Arbor press. Unsure of powder weight off hand, think 11.5 grns. Magic little round - more consistant with those 200+ yds shots than the 17HMR. Less noise than a larger capicity centrefire in built up areas also...happy days!
