[QUOTE="elkaholic, post: 1078040, member: 13833"] It just occured to me that using wax in the case mouth might not be a good idea! Here is why. When using a powder such as red dot in a large capacity case to fire form, you have a LOT of air space left in the case and the powder can be in various locations inside the case. This can potentially cause some STRANGE things to happen upon ignition. When I was pretty young, and even dumber than I am now, I loaded up some reduced loads using 75 grain Hornady bullets and a small charge of red dot shotgun powder in a 25=06. I was having fun shooting groups at around 2000', if I recall correctly. I had fired several rounds without any problems and suddenly one of the rounds just made a hissing sound instead of the normal pop. I grabbed the bolt to open eject the round and it felt like it was welded! I took it home and ended up using a piece of wood to hammer the bolt open. IT TOOK SOME EFFORT! When I finally got the bolt out, the case was fused into the bolt face and I had to pry it out with a pair of vice grips. The brass had melted into the extractor leaving a nice formed bump on the case head. I have no idea what the chamber pressure was, but it think it is safe to say that it exceeded SAAMI specs! Fortunately for me, the 700 action was STRONG or I would likely be resembling an ugly unicorn! Bottom line: I don't think I would try fire forming without a filler such as COW!.......Rich [/QUOTE]
