Well,I called Remington today. The LSS is in final inspection. Passed the range test. I asked what if any changes or procedures were performed on her. They lapped the bore and re-crowned the barrel. If there were material enough to do a lap job it leaves me to believe my hunch was right. They obviously lapped the the rear portion of it,as you can't lap the muzzle without cutting off an inch or two. If I'm not mistaken it tends to trumpet or funnel a bit and needs to be cut back and crowned. Could be the first few inches of the bore was tighter than the muzzle end. At any rate,I'll give her a wringing out when she gets back. Hopefully all will be peachy. If not it will be a 7 RM this time next year.
