No Joke! It can also happen with book starting loads with the slowest powders, especially when you are running 90grs or more. Really scary and pressure can get both weird and dangerous too!HOLY MOLY! I probably would have had to change my shorts once I got home too.
I'm the same, I just didn't want to start the age old argumentMe I never use mag primers, I find that the burn is more even and consistant and prevents "Bridging" even in RUMs, I have a post on here that explains my findings and reasoning I might look for it. Fifty Driver has some of the same views and findings.
I was in ABQ (Kirtland AFB) from 1996-2000. I know that there is at least a couple that is from the ABQ area. Post exactly what you need with your location.Albuquerque
If that what you are using that not a problem, and the gunsmith is correct, but watching for pressure is a must on any round that you load or primer you use. The primers all a little different.I have always used Magnum primers since I started reloading. Worked with an old gunsmith years ago and he stated that if you started load work up with magnums and watch for pressure signs you'll have no problems. So far that has worked. I load probably 60% of reloads with CCI 250's. Its worked well for me.
