Using once fired Norma brass, Federal Match large rifle primers, 55.0 grains of IMR 4350, and Berger 185 grain Hunting VLD bullets. They make one ragged hole in a 3 shot group at 100 yards from a Lead Sled. Really impressed with the accuracy, reading lots of controversy around fragmenting vs. controlled expansion. The differing opinions are nearly as polarized as the Lee FCD on most forums.
Very interesting read on setting the right COAL on Bergers website at: http://www.bergerbullets.com/getting-th ... our-rifle/
I ran through the exercise and there is a definitive sweet spot on the length!
As always, NEVER trust load data posted on a forum, validate and get your load data from the manufacturers or a manual!
