Accuracy and range
The rifle as originally manufactured was expected to be capable of firing at a range of up to 200 yards (183 meters) with a high hit rate. The musket was fairly accurate at medium distances, with a one in three chance of hitting a man-sized target at 100 yards (91 meters), but this accuracy diminished hugely at longer ranges. To increase the odds of a hit, massed ranks of 60–80 muskets were usually fired in a volley, which increased the chances of some musket balls hitting the intended targets. The Baker rifle was used by skirmishers facing their opponents in pairs, sniping at the enemy either from positions in front of the main lines, or from hidden positions in heights overlooking battlefields.
The accuracy of the rifle in capable hands is most famously demonstrated at the Battle of Cacabelos (during Moore's retreat to Corunna in 1809) by the action of Rifleman Thomas Plunkett (or Plunket) of the 1st Battalion, 95th Rifles, who shot French General Colbert at an unknown but long range (as much as 600 yards (550 m) according to some sources). He then shot Colbert's aide-de-camp, Latour-Maubourg, who went to the aid of his general, suggesting that the success of the first shot was not due to luck.
That rifleman Plunkett and others were able to regularly hit targets at ranges considered to be beyond the rifle's effective range speaks for both their marksmanship and the capabilities of the rifle.
