Re: Savage 338 lapua bullet setback
I am interested to see what suggestions come out of this thread, i am fighting set-back in a Savage .338 WM (don't think it has to do with the gun, just coincidence) as well as bullet tip deformation, it actually leaves a notch from where the front of the mag is overlapped and spot-welded. I am helping a friend setup this rifle to be a good all around gun to 500 yards, certainly not 1000+ performance needed, but past 300, you have to have things in good order for a first round hit everytime! We are loading 200gr Speer's to just over 3000fps, and getting tip deformation. I have been making sure the necks are dry and clean, no lube left, and that we are sizing the neck fully and have the setback fixed... for now. We have plenty of room in the mag so we glued a strip of rubber to the box to hopefully fix the deformation part, but don't know till we can shoot it again.
I cured setback with Bergers in my 7mm by turning the sizer in a bit more, and polishing my expander a bit, while removing lube from the neck, which has eliminated the problem for me. Good luck, hope you can figure it out!
