hi. i have a parker hale 1100 lwt in 308. from the chamber the rifling look clean and sharp edged. at the muzzle end there appears to be the four raised lands plus four marks.
is this right
Nothing to worry about.
It's where the bullets touches , all mine show pretty much the same.
Perfectly fine mate
good good thank you. just one of those things i hadnt noticed before. had my head torch on and then noticed the marks
