Howa Threaded Barrel Complete Specs and Full Gun Specifications

The M1500 was a fully new rifle, following the Howa Golden Bear hunting rifle that Howa Industries manufactured previously. When designing the M1500, Howa used the Weatherby Mark V - which was manufactured by Howa Industries on an OEM basis - as the reference. However, whereas Mark V's bolt opening / closing angle is 54 degrees narrow, the M1500 uses the more general 90 degree opening / closing angle.
