Hello This year I plan to compete in more IDPA and bowling pin matches. I've got a 19,23 and 27. I would like to get a longer sight radius and my plan was to buy a 17 and 34 but they are hard to find right now. I have found several 22s and 35s. I'm thinking I should just the 40s and start reloading. I've borrowed a 17 and the lower recoil than my 23 is very noticeable. I've done tons of reading but seem to only get pieces of answers. I would love to get your opinion on several questions. 1. How do you tell when it is time to trash your brass? 2. How many competition reloads do you get from 9mm vs 40 brass? 3. Many places I shoot my brass is bound to end up mixed up with other shooters or lost. Do you maintain a batch of hundreds of rounds and once this gets down to 100 or so throw the whole batch out? I envision every outing with say 100 rounds either gaining or losing quite a few cases. This seem like you would not want to maintain 50 or 100 round batches like I do with rifles. 4. Can I really make the 40 recoil like the 9? 5. Since most folks use the 9 should I just wait until they are available in my area? I've loaded thousands of precision rifle rounds so I'm pretty familiar with the process although I will have to buy a press that does more than one process at time. Thanks for you time.
