"But there is really no good reason to fuss with them."
Another TFL absolute statement of fact: not an opinion.
Several years ago, (5 ?) Schmit-Ruben K31s were sort of unusual. Not many people had them and ammo was hard to find. At that time, you could get Norma, and you could get Swiss military surplus. Both were expensive. Military surplus was selling here locally for $39/60 rounds. Norma was $39.95/20 rounds.
The Norma stuff was nice boxer primed ammo which obviously was selling for $2 each. And, it wasn't easy to find. I bought some and handloaded it.
The military surplus stuff was superb quality ammo. If you check out the forums that discuss loading 7.5 Swiss you will find very few people that ever come up with a handload that equals the accuracy of this mil-surp ammo. Further more, it comes in beautiful brass cases which are Berdan primed. Obviously, they cost 65 cents/ round. Even before I tried handloading them, I saved the cases because this was really nice brass: I couldn't bare throwing it away.
I shoot in a sport where we compete with bolt action military rifles without modification. In this sport, the K31 is a very good rifle. Very few rifles can match it's accuracy. The straight pull bolt makes it very fast and the stripper clips work as smooth as butter. Long story short, the K31 was my rifle of choice in this sport and I wanted to handload for it.
So, I looked into what it would take to handload Berdan primed cases. I found out that RCBS makes a tool for depriming the cases, so I bought one. I polished the cases, trimmed the cases, and deprimed the cases, but I had one thing holding me back, no primers. Shortly thereafter, a guy that also shoots these vintage bolt action rifle matches told me that he just purchased 20,000 Berdan primers from PMC (a local company located in Boulder City Nevada). So, we struck a deal. I gave him all my cases and promised him that I would scrounge every 7.5 Swiss case I could at these matches. I would also give him my decapper in exchange for him returning to me a reasonable amount of primed brass. This arangement has been working now for a year or more.
So, I have what I consider to be a good reason for handloading Berdan primed cases and I don't really care what the internet crowd thinks about it.
P.S. There are no decapping pins to line up. And the primers arn't crimped in. However, I process thousands of .30-06, 7.62 Nato, and 5.56 Nato cases with their boxer primers crimped in. I have a Dillon tool to remove the crimp. Again, no big deal.
