Hunters, I have experimented with several different powder choices; different bullets; and several 209 primers in my search for the best hunting load for my almost here 2015 Colorado cow elk black powder hunt. I am satisfied with using a hot CCI magnum 209 primer teamed with a 535 grain No Excuses bullet which is propelled by 90 grains (volume measure) of Black Horn powder substitute. I do place a wool wad between the powder charge and the heavy lead bullet. The rifle will be my old Remington 700 M.L. in .54 caliber. This weapon has been converted to a modern 209 primer ignition system. The accuracy is acceptable at the 100, the 150, and the 200 yard distances. I have a Lyman 57 peep rear sight and a Hi Viz new front bead sight with a green lite pipe. I do not advocate long distance shooting at elk with a black powder rifle. I intend on keeping my killing shot at the acceptable 100 yard distance. My rifle is more accurate than I am anymore with my 67 year old eye balls. I do wish each of you 'Good Hunting Luck' if you are taking to the western slopes in search of big game soon. I have a cow permit during the muzzle loader season in Colorado and I cannot wait to get there. Leaving southern Illinois the day after Labor Day. This Hunting load may not be the one for you but it is the one that I have selected for this hunt. Cow Tag
