I'm a 1st-time-Glock-owner (30) and a seasoned bullet caster/reloader (40 years). I'm finding that, if kept to reasonable velocities, my 230 grain Lee RN bullets over 4.1 grains of Tite Group work well, are fairly accurate, and don't mess up the OEM barrel too much. I also am a regular cleaner, so I clean it after I shoot it. Found the Lee 200-grain TC SWC to also work well but not their H&G 68 copy...the punkin ball loads were just more accurate. As always, YMMV, so work up your own load-I won't be responsible for your results, use the usual cautions. This 230-grain-bullet load, according to the Lee manual, starts at 4.0 of Tite Group and ends at 4.8, so I'm staying cautious. (It's 5 days before Christmas as I type this and just in case, have asked Santa for replacement barrel, just in case ). Anyway, anyone else out there in a similar situation? I'm retired and jacketed (or plated, for that matter) are too expensive. I can cast bullets from free wheel weights,tumble-lube them and put together loads for pennies each that still make decent groups at my backyard range. Anyone else?
