nothing to exciting. found a WRA 351 S L marked shell casing. made for a winchester 351 self loading rifle. i never heard of a 351 before. read it was made from 1907-1957 and it was the first self loading (semi automatic?) for hunting deer size game.it came with either a 5 or 10 round mag. it was short, rugged, heavy and very reliable. the russians even used them to some extent in both ww1 and ww2. thought it was kind of neat history. had good fun.
