A while back, I got the idea of applying heat shrink around the unsized Lyman Foster slug to increase the OD. I finally got around to doing it and the results were “ehh”.
I only used one type of powder and I noticed that fold crimp performed a little better than roll crimper. I suspect it’s because the ogive is more pronounced since it’s undersized. Anyway, tell me what y’all think.
