. This increased the typical effective range of a musket from about 50 yards to several hundred yards. The Model 1855 had an effective range of 500 yards and was deadly to over 1000 yards.

The barrel on the Model 1855 was .58 caliber, which was smaller than previous muskets. The Model 1816 Musket

The Model 1855 also used the Maynard tape primer

 system that had been previously developed. Instead of using individual caps which had to be placed for every shot, the Maynard system used a tape which was automatically fed every time the hammer was cocked, similar to the way a modern child's cap gun works. While the powder and minie ball still had to be loaded conventionally, the tape system was designed to automate the placing of the percussion cap and therefore speed up the overall rate of fire of the weapon. The Maynard tape system gave the Model 1855 a unique hump under the musket's hammer. The weapon could also be primed in the usual way with standard percussion caps if the tape was unavailable.

In the field, the Maynard tape-primer proved to be unreliable. Tests conducted between 1859 and 1861 found that half of the primers misfired, and also reported that the tape primer springs did not feed well. The greatest problem was the actual tape itself. Despite being advertised as waterproof, the paper strips proved to be susceptible to moisture. An attempt was made to remedy this problem by making the tape primers out of foil, but despite the improvement this brought, the Ordnance Department abandoned the Maynard system and went back to the standard percussion lock in later muskets like the Model 1861

 saw the Model 1855 simplified by the removal of the Maynard tape-primer and a few other minor alterations to make it cheaper and easier to manufacture, thus creating the ubiquitous Model 1861 Springfield. The Model 1855 was the best arm available at the beginning of the conflict as it took some time for the Model 1861s to be manufactured and actually reach the field. The Model 1855 saw action throughout the entire war and was used by both sides, as several thousand were stored in Southern arsenals when the war began.

First Use

The Model 1855 got its first test in September 1858 in the Pacific Northwest

(Spokane Plains) where the Northern tribes greatly outnumbered US troops. The attacking Native Americans were dispatched by US troops armed with the Model 1855 rifle-musket before they could get in range with their smoothbores. Lt. Lawrence Kip noted "Strange to say, not one of our men was injured...This was owing to the long range rifles now first used by our troops... Had these men been armed with those formerly used, the result of the fight, as to the loss on our side, would have been far different, for the enemy outnumbered us, and had all of the courage that we are accustomed to ascribe to Indian savages. But they were panic-struck by the effect of our fire at such great distances."

Variants

The Model 1855 is generally referred to as rifle-musket, since it was the same length as the muskets that it replaced. It had a 40 inch long barrel, and an overall length of 56 inches. Three rifle bands held the barrel to the stock. A shorter two band version, generally referred to as the Model 1855 rifle, was also produced. This shorter rifle had a 33 inch barrel and an overall length of 49 inches.

The Model 1855 musket was modified in 1858 to include a simpler rear sight (the typical flip-up leaf type), a patchbox on the side of the buttstock, and an iron nosecap to replace the brass one.
