RE: 209 primers - too hot or not?
I have used the kleenbores and 777 primers in my Optima. The expansion problem cayugad mentioned was a problem for me with the kleenbores. After a few shots, I would have to use a primer pick to get them out. I had more crud ring with them as well. I switched to 777 primers and do not seem to have as much crud and they do not expand.
