Description: Heym SR 30 Straight Pull Bolt Action. The rifle Heym SR 30, a hunting rifle, designed by a German arms manufacturer named "Heym". It is a straight-pull action with 6 ball bearings around the circumference of the bolt head. When the bolt handle is pushed forward, it forces a central plunger down the interior of the bolt body, forcing the 6.5 mm (0.256 in) diameter ball bearings out to lock into negative shaped (concave) recesses in the receiver. Pull the bolt handle back, and the plunger retracts, allowing the locking bearing to retract into the bolt body so the bolt can open. Heym states they successfully had the SR 30 lock up tested by the C.I.P. accredited Suhl proofhouse loaded up to 800.00 MPa (116,030 psi) pressure.
