1886 Winchester Black Powder Trial with Larger Bullet

The first trial a year ago with the 1886 Browning in 45-70 with black powder loads resulted in unstable bullets puncturing the target sideways or "keyholing" at a mere 50 yards. Two factors might have played a role. Bullet size may have been too small and velocity too high. With another Texas pig hunt coming up, it was time to re-evaluate and try a larger bullet along with reduced velocity in an attempt to stop the bullets from tumbling. Several loads are tested with a 405 grain bullet in .459 backed by Fg to FFFg black powder. Keyholing stopped and accuracy was best with the slower powders at 100 yards. Check out the video and see what worked and what did not.
