    .223 - 5.56

    I went from 22gr 2650 fps up to 23.8 2900 fps and couldn’t find a powder node. SD avgs 7-10 es 10-30. Out of a bolt gun. Anything above 23.7gr flattened and cratered primers bad. I’ll probably test around the 22.3gr mark at 2700 fps since that was the most consistent numbers and the best groups.

    What’s your load data and speed for a bolt gun?

    Why is my lapua 223 brass not chambering and sizing?

    Apparently no one reads all the updated posts. 😂😂😂

    Why is my lapua 223 brass not chambering and sizing?

    The load might be too hot with that double base powder and virgin brass. Size a few fired cases and try again to see if the primers pop. Can always go to cci450 or br4, cups are harder.

    Why is my lapua 223 brass not chambering and sizing?

    For reference I remeasured my Lapua brass using a hornady gauge and it’s about 1.457-1.460, using the Whidden gauge it’s 1.446-1.449. With the hornady gauge mine doesn’t seem as short as your chamber. So far fired hasn’t grown at all.

    I hear fishert&c does good work and Bugholes does good work too.

    .223 - 5.56

    I had the same experience with 8208xbr with 73 eldm, 73 Berger, 75 eldm and now 77SMK. From what I read the powder is not a good combination for heavier bullets in 223. I’m going to try imr4064 and see if that does any better. I have my doubts but that’s the only powder I have to test.

    I had the same thing with hornady 75 eldm using 8208xbr. Not sure if it’s the powder or the bullet. I think both, 8208xbr doesn’t like heavy bullets above 55gr from what I read. I was thinking about using imr4064, not sure if that’s going to be any better.

    I pushed the 77SMK to 2900 and only primer cratering. I’m using a 1:7 twist 26” barrel with 8208xbr. Maybe I have to retry 75 or 80 hornady’s with the bartlien. If you can shoot the cheapest bullet and get accuracy you need, more power to you!!! Once the barrel hits 100 rounds I’ll try...

    Damn that shit is screaming…. 🚀🚀🚀🚀 Hopefully barrel speeds up after 100 rounds or so. So far my bartlien 223 hasn’t sped up any after 65 rounds. I’m getting primer cratering going 2700 using the cci400 and Lapua brass with 77SMK. Have you tried the 80smk or 80.5 Berger or 85.5 Berger LRH?

    Easiest would be take the longest Lapua cases and ask him to headspace off that piece of brass. I’m sure when you get there and show him the virgin case he will know exactly what to do. Let him measure your brass with his tools so it’s more exact.

    I could use Starline too but I’m determined to get the damn Lapua brass to work. 😂😂😂

    Can always use sandpaper on a piece of glass and do figure 8 sanding on the shell holder. Cheaper alternative.

    Why is my lapua 223 brass not chambering and sizing?

    Haha hell yah Lapua 223 is like finding gold. I’m in the same boat except I have a Whidden die and it can bump the shoulder smaller. For $45 more you could just buy a Whidden die. Check out Brownells or midway they had all the Whidden dies on sale for cheap. If I knew I could use Starline...

    Why is my lapua 223 brass not chambering and sizing?

    Yup shave off the die or shell holder which ever is the easiest. Maybe you can borrow someone’s Redding competition shell holder kit. Or try another shell holder if you spares. Rechambering just going to take longer. Forget the SAAMI specs each go gauge is diff and each comparator is different...

    Why is my lapua 223 brass not chambering and sizing?

    Pierced primer sounds like over pressure from the case being too long or longer than your headspace. Try bumping the shoulder on the virgin Lapua brass down maybe .002-.003 and drop the load. Or at least to the same size as the Starline brass. It’s frustrating as hell but in the long run your...

    Why is my lapua 223 brass not chambering and sizing?

    Mine is also short chambered. Virgin Lapua brass is 1.446-1.449 and my chamber is 1.447 headspace. I got the headspace number from sizing down a scrap piece of brass till the bolt handle barely drops without using finger to close the bolt. Anything above 1.447 won’t chamber without a hard close...

    Why is my lapua 223 brass not chambering and sizing?

    Yup short headspace will do that to you. Supposedly it’s shorter so the case doesn’t have to expand so much upon first firing causing thinning in the case head. theory is there is no need to fire form brass, virgin brass fits the chamber perfect. Sounds like you need to take a few thousands off...
