I found some fired brass and a bullet, and learned a few things.

Two batches of brass: 20 Norma and 20 RWS.

For the Norma brass, the bullet dropped in without a problem.

For the RWS, the bullet fit in and out, but it was more of a "friction fit". Not difficult, but not wide open like the Norma.

Because both were fired from the same rifle, I looked closer.

RWS brass is a bit thicker than the Norma. I could see how the OD would be the same, but the ID would be a bit tighter.

Also, the RWS looked a bit longer, and as if there were a slight crimp in the end. I put my caliper on it, and the Norma was at 2.10, and the RWS at 2.11. My Forster case trimmer was still handy, so I threw it in. When RWS was down to 2.10, the bullet fit better. There was still friction (tighter ID), but better.

I think in the future I will be sure to anneal, and also swipe the inside of the rim with some emery paper. Just enough to reduce the friction.

But really need to figure out where the lands are.
