I have only saw a few instances where a primer change can get you in trouble. But WLRM is one of those primers where it can happen. If I were to change to WLRM, I would reworkup the load again. I might not go back to starting load, but definately lower than max.
You are certainly right, BC. But in my reading of the original message, this guy bought the Win. primers, and has not even started to develop his load yet.SO he is beginning at square one, which of course is where he SHOULD be starting..... witht he lightest starting load in his book.
Sadly, I think all of us reloaders sooner or later have to make the newbie mistakes to get a healthy respect of what we are doing when reloading. We are making a controled explosion.
I know I did. When I first started reloading, it was a 300win mag. I loaded and shot about 100 partition loads. I kept hearing great things about TBBC, but you couldn't find them as reloading components. So I bought 50 supposal TBBC off a guy at a gunshow for like 30 dollars. I figured why work up a load, just use your accurate partition load. WRONG. After hammering out the brass with a dowl, I learned something that day. You change a component, you are changing the entire load.
I have some articles from precision rifle, where they did controlled experiments on various primers. Its a pretty old article, called primer on primers, WLRM and 215's were the ones not to play around with.
