MOJET CUT RIFLE BARRELS
Mojet barrels are manufactured from imported stainless steel. Barrels are manufactured through a single cut rifled process which make Accugun a preferred manufacturer in South Africa. With any premium single-cut-rifle barrel that has been finish-lapped, the lay or direction of the finish is in the direction of the bullet travel, and so fouling is minimal compared to a barrel with internal tooling marks. This is true for any properly finish-lapped barrel regardless of how it is rifled. If it is not finish-lapped, there will be reamer marks left in the bore that are directly across the direction of the bullet travel. The goal is to get or keep the barrel clean while breaking in the throat with bullets being fired over it.
MOJET Barrels are manufactured to order; the twist, length (up to 32″) and profile are done to customer
specification.
VARMINT TARGET VS PALMA PROFILES
Between a straight taper and a Palma taper barrel of the same weight, it comes down to balance. More of the mass of the Palma taper is toward the shank end which moves the balance back towards the action. That brings the balance of the rifle back closer to the shooter which makes the rifle “feel” better balanced in positional shooting. The key to an accurate firearm is consistency. Getting everything to happen the same way for every shot is key to producing small groupings, and there are a large number of issues to be addressed in achieving an accurate firearm.
For long-range shooting we suggest a heavy and long barrel, the longer the bullet is in the barrel the further and faster it travels. When hunting or short distance shooting a light and short barrel will recommended.

BARREL BREAK-IN PROCEDURE
Any premium barrel that has been drilled and reamed will show reamer marks that are directly across the direction in which the bullet travels. It is essential to properly finish the barrel, such as your MOJET barrel.
The direction of the finishing is the same as that of the bullet’s trajectory, therefore fouling is minimal. The function of the break in the procedure is to break in the throat area off the barrel.
When the barrel is chambered, the reamer leaves marks perpendicular to the lands. When the bullet is fired, due to high pressure and temperature the copper dust is vaporized in the gas and carried down the barrel. As the gas expands and cools, the copper comes out of suspension and is deposited into the bore though this might fool one to believe that the barrel is fouling, it is in fact caused by the throat. The copper needs to be removed to prevent build-up. As the throat gets polished, the fouling will be reduced which is also an indication that the barrel is broken in.
