Re: Blackhorn 209 new black powder
Helps a lot. Thanks, Smokepole. I kinda intuitively knew that for a given chamber pressure, the larger hole would allow more gas and ejecta to flow into the primer/bolt area. You saved me a lot of frustrating time at the range. I’m sold on the benefits of BH, based on articles I’ve read by Randy Wakeman and Toby Bridges at sites like chuckhawks.com. Thought G.E.G286 wrote an excellent article above…….agrees with all I had read.
Interesting that my fave load for the Knight is the 285 gr. Barnes Spitfire………with 110 gr. T7 FFFg and Winchester ML primers. Very difficult loading with the Barnes sabots. Impossible second shot without thorough cleaning. Just switched to the Harverster ribbed sabots (yellow for boat tail bullets) and am very pleased with results so far. Easy loading and a single, 1.3" group. (There is an interesting article on our home page about the hazards of reaching conclusions from a single three shot group. As I understood it, imagine you fired 100 "numbered" shots…….1 thru 100 … and then randomly picked three shots. Would those three shots be representative of the 100? There is a small risk that the three picked are the three in the center of the group of 100……………or three on the perimeter of the 100………..with vastly different conclusions reached about that load)
