No its not on the handle its on the underside of the bolt body where it goes flat so it can seat properly on the receiver,,if you look towards the back of the receiver just under the bit which forms the hole for the bolt to slide in there is a small lug made of blued steel and this is the stop which the cartridges hit when thee bolt is withdrawn and it causes them to trip and spin outwards from the ejector lugs,,this lug is what has gouged a line into the underside on the bolt on my rifle,,,,,thanks again

as an afterthought maybe these photographs will help more than words,,on the receiver you can make out the lug I described to the rear sat in a depressed circle at the bottom,on the bolt the damage is at the front of the groove machined into the underside,its not a very big bit of damage but it causes the bolt to jam very tightly
many thanks for any ideas or opinions
