Re: umm crimping Berger 105 hunting vld ?
Crimping is not anything I'd do unless it was for a dangerous game rifle and the bullet has a cannulure for the crimp. I helped a friend put together an African bound 375 H and H and we crimped the hornady soft and solids.
Berger bullets do not require crimping to shoot accurately. I would suggest to you that you ignore the gentleman's methods and stick with varying neck tensions if you feel a need to do so.
Generally a neck tension of .002-.003" will work for most rifles.
Stay tuned as I am certain more members will add to this thread.
