We have spent many engineering hours perfecting the Mac Daddy feed ramp. Upon initial manufacture of the feed ramps we experienced many issues with failures to feed. The feed ramp geometry has now been centered with the barrel and magazine position. The ramp section has had its angle increased to point the bullet higher up into position with the barrel. Because of these geometry refinements the feed ramp is also no longer hit by the bottom of the bolt. These feed ramps will drop into your Mac Daddy style frames with little fitting required and have been tested to feed various types of bullets reliably.
We have tested these feed ramps with regular FMJ round nose, Semi wad cutter, and multiple jacketed hollow points. We will continue to test these feed ramps and make refinements to reduce fitting by the end user as time goes on.
