I am building a 7mm rem mag and did research here to find there was no stock bolt head that fit the axis in magnum configuration . I have built other guns but shy away from machining things that require specialty tools . The problem was the bolt head for a magnum came from bolt heads for 110"s . they are interchangeable but firing pin on the axis do not protrude . watched whole video setup on here on how to file down the size of bolthead to get proper protrusion of pin. i called pacific tool to see if they would make a bolt head for me with magnum face opened up from a short action bolthead . To my surprise they carry in stock a short action magnum bolt face that fits the axis. I installed it and every thing matches up . Firing pin protrusion is the same as the 308 bolt face. the part is the same length as original bolt head .
and extractor and ejector fit no problem . The bolt cycles nicely and all is well . I hope this opens up possibilities for others to use their axis rifles for magnum cartridges . If any one needs i can get part number from my packing slip but it is listed on their web site .
