to avoid the bolt handle catching the mag ring on the scope you will have to fit the cz or warne high rings, on the varmint models because the barrel is more or less in line (level) with the action the 44 will look ok. as long as your cheek is on the stock when looking through the scope this set up would be ok . however on both my 527 s varmint and american i found i was lifting my head completely of the stock so the scope would have to be lowered i did not want the stock modified plus on the american the scope was in my opinion was to far above the barrel the barrel. so the bolt handle would have to be modified, this turned out to be quite easy first fit the scope i found the med warne permantly attached rings to be almost perfect for my 3-12-50 s, remove the bolt handle from the bolt , turn the rear of the bolt 1/4 turn releasing the pressure of the handle which will then slip out very easily, place the handle in a soft mouthed vice gripping the "u" end of the bolt handle firmly but not enough to damage it so that the body and ball end is above the vice jaws, i used a fine grinding 1" stone the kind with a shaft that will fit into a hand drill, ithen proceeded to slowly grind down the meaty part of the bolt handle ( just above the bored1/8"hole on the handle), moving the drill up and down the shaft of the bolt handle at the part it was catching the mag ring, it is important to be smooth in your operation of the drill, so the bolt handle retaines it shape (dont just hold the drill in one place). the handle can be removed and refitted temporaly in the bolt to see if you have ground it enough, when the handle cleares the mag ring it can the be polished up again i used a shafted polishing wheel finishing it off with fine wet and dry paper untill it is silky smooth. it can then be re- blacked with any cold- black product. i have now done a few of these and believe me they look, feel and will shoot better because the scope is closer to the barrel.
