    Brass was as stated. I will order more.

  2. Rated 4 out of 5


    I had to resize all the cases as the necks were slightly undersize and I was collapsing the neck. This was with .308 cal, 110gr JRN pulled from GI .30 carbine. No problem loading after neck resize using standard RCBS .300 BLK sizing die. Otherwise, excellent brass.

    I ordered 100 pcs to check the quality of their processing. I am 100% satisfied with the quality and detail to the brass processing. I will be sending brass to be converted very soon.

    This is the best looking brass I have seen,being that it is reformed 223. It’s clean,no dents, primer pockets clean too.GOOD STUFF

  8. Rated 4 out of 5


    Brass is pretty good, a handful have some dings and dents, not bad enough for me to just toss, but most are fine so it’s not a huge deal.

    Received 102 pieces yesterday, all of which were LC 11 head stamp. you have to look real close to see it is indeed once fired brass most of it looks new. when dealer says it’s as close as it gets to new brass he is not exaggerating. also shipped extremely fast

    I was surprised with the quality of this brass. All cases were preped , clean, and sized right. Price cant be beat. If you reload blackout ammo, buy from this guy. I firmly believe he checks the cases like he advertises he does! I will order more.

    Lightning fast shipping. Brass looks like new as stated by seller. Priced well. He puts to shame the other brass sellers who take their sweet time in shipping.
