[QUOTE="esshup, post: 2044572, member: 11101"] Are you dropping the powder in the case or weighing each charge and then putting the powder in the case? The only time I had problems with powder "bridging" was when using a powder drop, and it was bridging before it reached the case. I'm loading RL-50 in a 7mm Allen Magnum (fiftydrivers design) and have no issues. Kirby said they had bridging issues, and said use RL-33 to get away from the temp sensitivity of the WC-872 that I was using, but I'm assuming that it was in the loading process. He also recommended just using a standard Federal 215 primer not a GM215M primer. No issues at all lighting 102 grains of it and the last 3 loads that I chrono'd had a high fps of 3225 and a low fps of 3219 pushing a 195g Berger EOL bullet. [/QUOTE]
