Built on a GMA African Magnum action. This is a true cannon that delivers a 600 grain bullet @ 2,350 fps. Ralf filed and sighted the iron sights in without the muzzlebreak and received a decent thumping whilst doing so! 24″ Krieger barrel with integral fittings. The stock is highly reinforced and has two recoil reducers installed. LOP 14 1/4″ Ralf made a removable muzzle break for this sledgehammer. Weighs in at just under 13 lbs.
