[QUOTE="NZ Longranger, post: 494737, member: 14"] Sounds like you're on the right track with your loads. Our version of the 7mm/300 Norma we call the 7mm FatMax, as its the longest version of our 7mm Fatso's we can fit in a short action, all but a seriously lengthened one though. US 869 is the best powder we've found, and produces 3250 to 3300 fps with 98 to 100 grains with the 180 Berger VLD's and Hybrids at a measured 65,000 psi out of a 26" barrel. The tighter Lilja's etc are closer to 3250, while most other barrels will run 3300 fps. Our chambering has a BTO with the Hybrids of 2.790" for a 15 thou jump, or with the VLD's its a BTO of 2.785" for a 15 thou jam. Sounds like your throat and/or neck might be a bit shorter if you're 2.718" with the VLD's, depending on whether you're jumping or jamming? Greg [/QUOTE]
