[QUOTE="Mad Professor, post: 3543624, member: 5316"] Are you trying to load them for a self-defense round? If so, I would not use TiteGroup. IMO, TightGroup is too fast a powder to bring it to SD velocities. It starts having issues with a 124g bullet around 1100fps. There are several options that will easily exceed 1200fps without severe over pressure problems. Are they solid Copper? If so, they will likely be longer to make the same weight, further reducing the volume for the powder charge. Another potential issue with TG. I believe N350, 3N37, maybe 3N38 would be a better choice. Look at a powder burn rate chart to get an idea. [/QUOTE]
