One of the initiations into lee loaders is the inevitable detonation of a primer slightly off centered- BTDT.Lee makes a seperate priming tool; inexpensive, easy to use and totally defeats the concept of a packable field kit.I found a quality MATCH hand reamer that trues up the pocket and the flashhole reamers make for a more pleasant reloading session. I've had reloaders role their eyes as I use match reloading techniques on cartridges and rifle chambers that defy match specifications and criteria. I now only reload for my old survival SMLE. In spite of a fresh #1 headbolt, it has the generous chambering that makes this a dependable field piece. Many of the lee loaders only neck size, which is a major trick in accuracy using cases once fired in the same firearm. You do have to run them through the action to make sure they chamber. And some, like the .30- 30 with back locking bolts can somtimes be tempermental.
The key to reloading is consistency, which also helps with safety. I've put .303 loads together that give service match rifles upset stomachs.
Whats worse, I sometimes shoot with a WW2 marine vet who pulls out a beautifull early production 7.7 Arisaka with crysanthemum. And he whips EVERYBODY.
