Ramped Barrels
kenjuudo: I agree with dclark on this issue. I have seen many and have shot a few and it doesn't seem to matter with the 45. With the 38 Super - if you are going to go the high pressure route with max loads it may be worthwhile but it depends on what you would want to do with a 38 Super. If you're just brewing up your own reloads and having fun, I don't think you would need it. If you are going 'major', it may be worth the investment.
I've 'popped' a few 38 Super cases in my time but those were all my fault. When I have stayed within the parameters in the loading manuals I have not had a problem. Even using the older manuals and the charges listed haven't caused me any problems. Again, it just depends on what you would want to do with it. Hope this helps. Mikey.
