Funny that you say that. Had exactly the same experience with the new batch of AR2209 - and the already accurate 6.5CM got even better: https://i.ibb.co/vvzggVR/Full-Size-Render.jpg...

Interesting thread and well suited to a campfire and beers. :) I have oft puzzled over poi changes between okd and new loads. I've decided that such things as slight changes in neck tension due to...

This mirrors my experience exactly. Both my .243 Win and 6.5CM shot high on the drop tests when I started a fresh batch. The old batch was 2012, the new batch 2019. Velocity increased about 70fps...

I use 2208, purchasing large (10 or 20 kg) lots so I don't change batches often. (We use between 10 & 15 kg a year) The last time I had a batch change in 2208 I loaded 24 rounds with the old...

It's a Bergara HMR, I dont have a chronograph so have no exact way other than trying the crude 100-300m drop with a ballistic calculator. Be a real shame if I have to drop this load but if that saves...

Yes This Above. So to summarise, if the case has been sized so that it is too short for the particular chamber when it stretches at firing there can be separation. Which means that the 'ideal' case...

Almost correct, what causes case head separation in that area is not actually anything to do with the die working the brass in that area....the die actually sizes very little near the case head....

Grandpa Mac's explanation is the correct one. The case wall thickness tapers from thin at the mouth to thick at the base. When you fire it, most of the case expands, gripping the chamber wall. ...
