280ai manson reamer issues

[YoungGun96]

Recently had a 280ai built on a blueprinted rem 700 action with an ibi barrel. Chamber was cut with a brand new manson 280ai live pilot reamer using new Mason go and no go gauges. Now that the rifle is built the throat is so short factory ammo jams into the rifling and will rip lighter bullets right our of the case. Has anyone else had issues with manson 280ai reamers?

Ask the reamer owner why the reamer was ordered with such a short throat. Fairly easy fix to throat it longer... just about every smith has a throating reamer for 7mm. It sounds like it needs to be longer by 30 thou.

The reamer was ordered as a standard 280ai with no modifications requested. Being as I have no experience with manson reamers, are they always short throated unless requested otherwise?

I think a longer throat needs to be requested if that is what one wants... Short throats are generally better for longer accuracy period. Ask Manson about your problem and let him know what factory ammo you are having problem with.
