So does NOE bullet molds.

I have a two cavity NOE mold with one cavity gaschecked and the other is plain base. The gas check bullet makes a great full power 30-06, I have been able to run them up to 2250fps with accuracy good enough for hunting. On the other hand I load a lot of 30-06 rounds with the plain base version and 9.5gr of trailboss for a sub sonic plinker and rabbit load.

I had a 300 whisper before it was cool, but after I found out how easy the 30-06 was to down load with that bullet I sold my 300 upper and have been playing with my 30-06 since. I did manage to kill a couple antelope with it before it hit the road though, 125gr Nosler Ballistic tips in the 2250fps range worked very well, almost as good as the same bullet at 3350fps from my 06.
