QuickLoad cartridge data for polyonal rifling
QuickLoad, at Data: add, load, change, save> Case/Caliber data> Change data records in active file> Cross-sectional bore area> Calc lets you select "HK Polygon Rifling" or "Normal Rifling". If you select HK Polygon Rifling" you must input Caliber (groove", Caliber )bore), Larger Radius R, Small Radius r, and Number of Grooves.
I may be overthinking this, but under the assumptions that polygonally-rifled barrels actually perform differently than conventional ones, that "HK Polygon Rifling" (although I believe HK's are octagonal rather than hexagonal like the Glock) is similar to Glock polygonal rifling, and that QuickLoad effectively uses this data, I'd prefer to have data there that matches my Glock 19. I can't find the groove or radius data anywhere. Do any of you know the correct values for the Glock's "lands and grooves" (sic)? Thanks. |

The assumption is that you will slug your bore and use the numbers from your own firearm, for more precise results.
