The reason I mentioned 500 yd is because that would be my personal limit for a game animal. I practice out to 500 frequently at my range. My 7mm-08 has a 23" proof barrel and must be a fast barrel as I am .5 grain under max with no pressure signs and yet the chrono shows 2960. The JBM ballistic calc says just over 2000fps at 500 and a little over 1300 energy. I was looking to see what real world info was out there on a 7mm-08 out to the 500 yard mark. I'm thinking I might need to look towards a bigger hammer for the elk if I want to shoot that far. So either I spend the money on an elk rifle set up or live with a shorter max range.
