I have some .375 bullets that I got when I purchased some 38-55 supplies that are too small for my old barrel in 38-55.
I have 34 each .282 gr .375. Not gas checked by Hunter Supply,but have the base cast for one.. I also have 38 each 282 gr., Gas checked that ware marked Lyman # 375296.

If interested PM me.You can have them for paying shipping of a small USPS Flat Rate box.I think those are $8.75 now

If God wanted you to walk and carry things on your back, He would not have invented stirrups and pack saddles
