I read a lot of threads where people talk about case bulge. I have 3 new Glocks (purchased new in the last 6 months) and reload for them all. I have a G-20SF, G-17 and G-23 RTF2. I do not load to max capacities for the range and use my stock barrel in all. I have not experienced any case bulge yet. I have shot my 10mm brass about 6 times and no issues. Has Glock improved their chamber support or is it because of my loads? Or Both. What have you all experienced?
