Here's a question to all of you more knowledgeable guys out there. I'm wondering what caliber provides more ultimately superior ballistic capabilities, either 45 Super or 10mm? I've done a little research into both calibers, however I still have a lot to learn. Judging by what I've seen, I was under the impression 10mm brass from certain manufacturers is capable of handling significantly higher pressure levels, and because of this I also thought you could load them really hot to far surpass the capabilities of 45 Super? I remember reading something about certain 10mm brass being capable of withstanding up to ~50,000cup and 45 Super only being able to withstand ~28,000-30,000cup. The reason I'm asking is, in the not too distant future, I'd really like to experiment with one of these calibers. I may just experiment with both, however I would like to learn more about both regardless. Any input is much appreciated.
