Hello everyone, newbie here. I'm new to the forums, but I've been shooting for most of my life. I have recently bought everything needed to start reloading for my 7mm rem mag, and I've hit a snag. I was planning on using berger 168gr vld bullets, but I couldn't find any local to me, so I bought some 168gr accubond long range bullets. Since I was planning on using bergers, I bought some retumbo. Nosler doesn't have any data for retumbo, and hodgdon has no data for 168gr bullets. Would I be safe to use the data that is in my berger manual as a starting point? Has anyone loaded with this combo? Thanks in advance for any insight.
