Hi dmar,
I use them for a wide range of 9mm loads.
If it is what you can get I would (I do) use them. I doubt that you notice much difference with the exception of the near max or maximum loads.
I'd develop a load like you would with any other primer and you should be fine.
Prior to these I had a ton of small rifle primers and I used them in any and all kinds of sp loads with out any problems.
Good luck and be careful.
Mike
