I know that many people claim that shooting cast bullets in Glocks is Verbotten but there are many that say no problem, some say you can get away with it in a 9mm but don't do it in a 40. I'm guessing the truth may be someplace in between.
I recently purchased a Star sizer (love it!) and it came with a tube of Javelina alox bullet lube so I went ahead and used it up. Sticky, smelly and downright hard to work with as far as loading in my press is concerned. I lubed up a bunch of 153 gr. Lee RN 38 super bullets and loaded them in my 9mm trying to duplicate my 147 gr. jacketed load. I was a little worried about shooting them in the Glock so I fired them very sparingly in the factory barreled M17 and M26 and shot the rest up in my Lone Wolf barreled M34.
I was rewarded with excellent groups and the real surprise came when it came time to clean the barrel. In the past I had used Thompson Blue Angel and would see some leading. I haven't tried the thompson lubed bullets in my 17 yet but I was impressed with the Javelina lube. I ran a clean patch through the barrel and then brushed. There was no initial resistance which changed to smooth after several brush strokes. It was smooth from the begining. One or two passes with the brush eliminated any streaks and the barrel was clean with no signs of fouling.
Is there a bullet lube that is as effective as the Javelina without the mess like Thompson Blue angel? One of the local casters that made some really great bullets for me years ago used a hard red lube, similar to Blue angel, that I thought was great, any ideas on what that could have been?
I probably will heed their advice to some degree and use an aftermarket barrel in my 40 Glock and 45, I've seen the same guy blow out his mag or his extractor and bulge some cases in a 40. In the 9mm however, I may have to experiment a bit more.
What are your thoughts? Thanks.
