ok so I am finally getting around to doing some cast loads in my AR. I bought the lee 312-155-2r and cast, sized and powder coated some boolits. I was loading them last night and seam to have a COAL issue for some reason. I see most people claiming around 2.02" - 2.10" COAL for this boolit , but if I load anything longer than 1.99"ish , the ogive of the bullet jams into the end of the chamber and sticks.I get a nice ring around the end of the boolit. At a COAL of 2.02" the ring on the boolit was about .26 from the tip of the boolit, with a case trim length of 1.358" - 1.360". Now if I load to the 1.99 there is no issue and everything hand cycles just fine
I actually had a dummy round get stuck, which pulled the boolit out of the case. I had to use a dowel to pop it out.
So what COAL are you loading for this combo?
thanks charlie
