I don't know Larry I have only been in this HBR game for a short time. Last winter when Mike was so kindly and professional putting my rifle together, I went to a large gun show and purchused 5000 210M primers. So far all had the red sealant on them. I also picked up some 205M and those have a purple sealant on them. That is if its sealant? Not really sure what it is but its red on Large and purple on small. And now another question. For those that mix their own cleaning solvent. Does anyone use GM Top engine cleaner stright or do you mix it with (Kroil) or some such spelling????
