Bartlein are experienced shooters, reloaders and hunters who have been working in the firearms industry for over 15 years, everything from working for a barrel maker to retail firearms sales. Together, they have been involved in firearms for over 30 years.
Bartlein always look to expand their knowledge in the firearms field and improve firearms that are being designed and existing models. Everything from hand guns, bolt action hunting rifles, competition rifles and even machine guns. Their desire is to make the best and be the best.
The uniformity in their barrels and finish of the bores is second to none. Their rifling machines are so accurate, they can carry the twist rate to the 4th decimal point (example: 11.3642). The process of Single Point Cut Rifling is the most stress free way to rifle a barrel. The twist is exact, where as other forms of rifling can have variances due to the process they use. Also, the bore and groove dimensions are more uniform.
They pre-lap our barrels before rifling and finish lap the barrel after rifling. There is no need or under any circumstances, should you fire lap or do any other sort of bore polishing to the barrel. Contrary to what others say, a lapped barrel will not wear out earlier vs. an unlapped one. In our experience, their barrels will typically last longer than a button barrel, etc.
