I may be wrong but it seems to me #34 and #41 are nothing but Large rifle mag and small rifle mag...at a higher cot of course
My understanding is that these primers are harder to ignite (primer cup material is harder, or thicker, or the anvil is set farther from the firing pin to prevent slam fires in autoloading rifles, or whatever other theory is out there). I don't believe the primer should be considered as a magnum, but I am open to correction. These were the only large rifle primers in stock.
I will be using them in FAL semi-auto, and Mauser bolt action rifles. I hope they work in both.
