Very puzzled. I made up a big batch of a clone of the Lyman 311407 from the Boolits group buys from a few years back. A Loverin style with multiple grease grooves. It starts out with a major diameter of 0.316" and 0.310" top bands and a 0.304" nose. I sized them (with speed green lube in the grooves) to 0.314. They were loaded with loving care (weight sort, all the bells and whistles) in a 30-06 and shot in a M1903A3 with a known large throat. With 16.5 AL 2400, WLR and the GC at the bottom of the neck with a neck tension of 0.001". Out of 10 two or three will be on target and then the rest keep making a larger and larger pattern. At the Mil-National in 2016 I managed to make plenty of enemies due to cross fire etc. I shot some last weekend and managed a 35/300 in a CMP match. I have since pulled the rest and will switch to a 314299 and see where that goes. There is no leading that I can find in the barrel. I am just baffled. I can see a wide group but flyers off the paper with no rhyme or reason are really crazy. The fat nose and relatively deep seating may have something to do with it but i am still at a loss for the crazy shooting these do.
