The other day, I found approximately 100 H&G 68s already sized and lubed so I decided to load them up before switching out die heads on the Dillon 550.
My standard load for the #68s has been 5.4 gr. of W/W 231 @ an OAL of 1.250"-1.260" since the 1980s. Familiarity breeds complacency... So, I dumped 100 primers into my flipper then into my primer tube. loaded a few rounds, checked my powder charge and OAL which were fine. I quickly loaded the .45 ACP ammo because I wanted to switch over to 9 mm.
I always follow the "only one container of powder and one type of primer on the bench, at a time" rule. As I was cleaning up in preparation for the switch over I realized that I had loaded the 100 rounds using Winchester LP magnum primers instead of regular LP primers!
Are these safe to shoot in my 5" steel 1911s or should I pull them down? How much will the magnum primers increase pressure over the standard primers? Thanks for your input, Treetop
