I don't recommend them either but the fact is that they worked flawlessly in temps from 30ish-70F in the Lehigh designed plug and even in some you made for me. These are not common hunting temps for a large part the country but in Missouri they are common some years.
I only did it to push the limits of the plug design with bullets from 180gr to 385gr in three different calibers. Not one had an issue or excessive carbon build up. Fiochii primers will not fit my Lehigh or i would have tried them too. They worked fine in the modded CVA plug also.
