Re: 7mm rum 7mm rm 180 vld velocities
I can speak for the powder load part. Most if not all manuals are going to be conservative. The reason being is the lawyer setting at the desk at the company telling everyone it has to be safe. To many different rifles hand max loads at different pressures. So they post a max load that should be with in the original design of the pressures listed by the creator of the caliber. Hope this helps with the load info. I generally put loads together that are 1 to 1.5 grains over max without any problems.
I like your numbers for the 180's out of the Rem Mag. That is encouraging.
