  1. for a novice like myself, that was most instructive. Like the shooter, I’m surprised at how poorly the Zionist ammo performed. From now on I buy domestic gefilte fish only

      A few yrs ago there was a military ammo shortage and the US military was buying additional small arms ammo from IVI (Canada) and IMI (Israel). I got a batch of range pickup 5.56 brass and it was LC, IVI and IMI mix.
      Perhaps there’s a reason that shit shot so bad (export only!), because IMI is supposed to be pretty accurate stuff, well, the stuff they keep for themselves.

  2. For decades to come the gun forum pundits will wonder how these people used two different types of ammunition (5.56/.223) without turning their guns into frag grenades.

  3. I have hand loaded all my centerfire since the 70’s. When there was lots of cheap surplus around I shot plenty of that, but otherwise hand loads. I would advise anyone loading their own to be opportunistic when buying components. I.e. look for deals. They’re out there. My 55 grain FMJBT .223 (Berry’s bullets, small rifle primer, WC846 surplus propellant which is BL-C2) loads current cost is $.21/rd which WAY below commercial prices (less than half) and that’s with me assigning $.04/rd for brass consumption. I have a 5 gallon bucket full of once fired .223 brass. For pistol loads I definitely recommend shooting a good quality super hard cast, poly coated bullet. 9MM 124 grain round nose for practice/plinking current cost is $.13/rd.

    • If you have the time and lead available, you can’t really get much cheaper than casting your own for pistol (and rifle!). I haven’t found anything from a factory that shoots better than my cast 200gr SWCs out of my .45s, or that hit harder than my 400gr slugs out of my .480.
      If you have a 30-06 (long neck makes it really easy to work with), especially an old springfield, there are a multitude of moulds that will let you practice with it for about what it costs to shoot a .22.

  4. Excellent write up. It was very quickly apparent that the author had a good technical background and knew what he was talking about. I got to the end of the article and noticed the author’s name- yep seen him on various handloading and competition forums in the past. Solid source.

    I had . Comment from a trainer a few years ago when I was running pmc xtac in a carbine course. He reminded me to always check my zero as the pmc xtac was a few hundred fps slower than m193. I’Ve never bothered to chrono it as its cheap plinking/short range training ammo to me, but it looks like he was spot on correct.

  5. Federal Lake City – when you can find it.

    I recently bought a can of the jew IMI brand and afterwards also noticed it’s inferior qualities. That nation really needs to be wiped from the face of the earth. Take Take Take Take nothing but gimmedats over there too. Nuke ’em. Nuke everyone.

  6. Impressive work. Thanks for posting.
