I know this will sound a little foolish on my part and is definitely a newbie mistake, but I bought a bulk bag of 500 Copper jacketed 180gr 40cal target rounds at the last gun show “about a month ago”. I did not notice at the time that there was no brand name written on the bag. Do any of you have any suggestions on what I should do, or how to identify them so I can find a recipe in my manuals that is safe? I see there are different recipes for this round per manufacture. I bought 500 22 cal 55gr rounds of copper jacketed for the AR-15 at the same time that are Winchester. I just did not look closely enough at the 40Cal bulk bag that just said 180gr copper jacketed.
