Going to be handloading for a Remington Sendero in 7mm Remington Magnum. It has a 26" SS fluted barrel with a 9.25 twist. It will be used in two different places, North Florida for Whites from 200-300 yards. Out west for Elk, don't know the yadage out west. In looking at Quickload, RL-25 seems to be a great powder, but I'm concerned about temperature sensitivity. Started looking at H1000. You don't get the velocities with H1000, but you don't have to worry about temperature swings. Would like to use the 160 Sierra Gamking for deer. What are real world experience with H1000 in the 7mm rem mag? Also recommend a good Elk bullet.
