.36-Caliber Colt Conicals: Testing The 17-Grain Load
This video tests .36 caliber Colt conical bullets in an 1851 Colt Navy revolver using two different 17-grain powder charges: Goex Triple FG black powder and Pyrodex P substitute. The Goex load resulted in a lower average velocity (732.4 fps) and a wider spread, with the instructor expressing dissatisfaction with the grouping at 50 feet. The Pyrodex P load yielded a higher average velocity (866.6 fps) and a slightly wider spread, but performed better overall in this specific test. The instructor notes that 17 grains may not be the optimal load for this bullet type and plans further testing.
