Hi guys! I'm looking for a mold to make boolits for my Marlin 336. Does anyone have experience with the RCBS 30-180-FN bullet? I'm using the rifle for Cowboy Lever-action Silhouette matches and need to have some punch for the 200 meter rams, so I'd like to stay around 170 - 190 grains bullet weight. What are your experiences in this range? Or, how about the SAECO 180 gr FP?
