Need some new caster help. I'm attempting to cast some 245497 boolits from straight wheel weights for my 6mm TCU. The bullets are casting just slightly out of round at .245 across the bands 90* from the seam and .246+ along the seam. That's not a problem in my mind as the sizer should fix that. My question is what should these cast at the heel? No matter what brand of gas check I try they are extremely loose. This is a single cavity mold. The heel is running right at 230 90* across the seam and .233 along the seam. Checks don't clip on at all and can be pulled right off after sizing in a Homemade Lee style die that sizes at .2445. Does anybody have a spec on what the heel of a .244 bullet should run? Fillout on these bullets is decent. The heel looks nice and square on the corner but appears almost tapered. It does in fact mic at .236 right behind the rearmost driving band. Any ideas?
Second question: If I seat these with the check still in the neck. I end up with 3 grease grooves and the crimp groove outside the case. Are these exposed grooves to be lubed or unlubed? The throat on my Contender barrel is long enough to seat these out this far and still chamber.
Thanks in advance for your replies. Rockydog
