7mm 300wm imp.
Sorry, I don't have Quickload, but I do have personal experience to share. I have a Browning A-Bolt SS originally chambered in 7mm Rem. Mag. that I hotloaded for too long and shot out the throat. The bbl is pretty worn too and will only shoot really tight groups with light bullets. I rented a 7mm 300Wby reamer, and cut the chamber out until 300win brass would barely chamber. After doing this, I realized that the neck on the wby chamber was much longer than the 300 win brass that I was using, so I have to push the shoulder back on full length brass to get good cases now.
Anyhow, my gun likes moly coated, 120 grain TSX's with 82 grains of reloader 25. This has low ES and chrono's 3750. Probably too hot in a gun with a tighter bbl so use extreme care working up a load. I generally use 7mm wby maximum data for starting loads in my cartridge. I used to do well with coated 150 nosler BT's and around 76 grains of reloader 25 for about 3350 fps but groups are too sloppy for more than 400 yards. The 120 TSX's will shoot about 3" at 600 yards in NO wind. I took a whitetail doe at 666 yards with that outfit last season.
