Thank you guys for all the information! I'll see if I can post some pictures later on today to see if a visual would be helpful. I've been loading 124gr Hornady FMJ-RN to 1.250 as the starting point and once I experienced feeding issues I started to play with the OAL. I plunk tested the chamber and I went up to 1.275 and the round still spun freely with full support of the casing, but didn't want to go higher because 1.280 is the recommended max for .38 super. And for what it's worth I have a Schuemann Ultimatch barrel. The ramp/chamber corner doesn't seem to be abnormally sharp or angled to effect feeding but I'll let someone more experienced than I make that determination. Yes Bamboo, that is the issue I'm having and thank you for the variable listing. I'll have to measure the feed lips for sure and try that out. Just trying to get a list going to weed possibilities out. So far I'll be looking at recoil spring, ejector, extractor, ramp/chambering, and magazine feeds lips. Thanks again, great info guys.
