Re: delemma...what 338 chambered rifle to start with?
I'm not familiar with that bolt design, but it wouldn't be hard. I'm sure it's a big thick one.
I counted 5 ejector marks pretty easily seen, 3 more if you looked real hard. No biggie, I've seen remington stuff that could have used filing back down, if you felt like using with loose primer pockets. I've got marks on some of these 30-338 Lapua brass that is close to what the 338/416 case has, not raised, but marked.
I don't like to see any marks get raised, just screws up headspace and creats hastles chambering when the die is set perfectly tight already. You can measure it with a caliper, if you run 001" - .002" headspace, but have a .002" - .004" extrusion, you now have tight headspace, and out of square casehead, and consistancy just went to hell.
I'd choose one with no ejector if I spent the money on one.
