[QUOTE="Litrfoot, post: 2808178, member: 108596"] Glock 20SF - 4.6“ KKM barrel - 22lb spring. So i was able to test the BE-86 the Rim Rock 220 hardcast. Here is the results. ———- Be-86 6.5gr, Starline brass, CCI LG primer, 1.248 OAL, 220LDFP HC 5 shot: AVG. 1063fps ES 17.5, SD 6.2. Good accuracy. ———— BE-86 6.6gr, 1.248OAL, 220 HC 5 shot: AVG. 1068fps, ES 31, SD 22 ———— BE-86 6.8gr, 1.248OAL, 220HC 5 shot: AVG. 1080fps, ES 68, SD 30. Note: primers just starting to flatten out and slight flow around firing pin. ———- I then went back and shot the 6.5gr load again with ten rounds. BE-86 6.5gr, 1.248OAL, 220HC 10 shot: AVG. 1062, ES 18, SD 7.69 This 6.5gr load is where will focus. I will use this load to practice and use the Buffalo Bore factory ammunition for bear protection. Buffalo Bore states in their testing, ”4.6 inch Barrel yielded 1140fps. I’m not willing to push any load to find that speed without the knowledge of the exact powder and lot number they have used. Speculation of the powder used, Power Pistol or BE-86, observation from bullet pull downs on 10mm-firearms.com. The reason I used 1.248OAL was that another fellow had problems with feeding so I pushed it back for the testing. I had no FTF during testing with these loads. In fact I also loaded up 5 @ 1.255OAL and shot them with no FTF. So I will test some more at that OAL, 1.255, and grab some speeds and function tests. Note: these are my loads, with my equipment, and with new star line brass. Shooters must always use safe starting loads produced from reliable sources, i.e. manufactures DATA or published reloaded manuals and work up! I share these results as info only! As I stated in the previous post, a stock barrel with factory dangerous game loads created bulges in the brass. I would not reload that brass again, nor would I feel comfortable shooting these types loads from a stock Glock barrel. [/QUOTE]
