Right now I have a rifle chambered in 7mm Remington Mag, a 25" 5R barrel and its throated for 180gr. SMKs.
Recently I saw the Berger 180gr. hybrid VLDs and was interested in them since they supposedly are much more tolerant to bullet jump, and have a G7 BC of .345 when not even tipped ( G1 of around .670 IIRC? ).
As I don't have access to Shooter or ATRAG software, or Sierra's V5 load development program, I was curious if there's a starting point anyone had for this bullet using Retumbo powder. I'm also curious what can be done with a longer barrel up to 30", and Retumbo or even RL17 powders.
Any thoughts, experiences, data or otherwise would be greatly appreciated.
