I am looking for advice for an accurate plinking mold for my Marlin 336 with microgroove barrel in 35 Remington. I would guess that a 158 grain cowboy mold may fill the requirement. Will any of these boolits begin to engrave the rifling at loaded OAL?
Molds that I am eyeing are: RCBS 38-158-CM, Lyman 358665, Saeco #358 FN.
I will be using my LAM II with a .360 die that sizes to .3595".
Thank you
Clark
