You stated the problem when you said bertram.

measure the neck wall thickness of the h and b brass, and compare... i BET it's .002 or more THINNER on the bertram and therein lies the problem.

you are also seeing that the baser resizes FAR more than the horneber, right?

if it aint broke, dont fixit, i say

Gentlemen

I have some brass from Kynamco Bertram brass I think
The cases was loaded by Kynamco and they expanded more then my Horneber cases from WR munition.
I think that Kynamco loaded them too hot!
I have a problem re-sezing them so that they hold the bullet tight. Any advice !!

They are for sale

Cheers,

Andr�
