Got my best results for a 168gr. Barnes TSX using IMR 4350 in my Browning A-bolt. It pretty much rejected IMR 7828 and RL 22. The 4350 loads are clocking right at 3,225 fps and grouping 1/2 in. at 100 yds.,,, As for the case failure concern I have eliminated mine on my belted magnum cases by neck sizing only and annealing the necks before every 4th sizing . If you end up using hot loads on a regular basis and get brass that is hard to chamber but the oal is right, the shoulder setback isnt too long then you most likely will be suffering from case bulge just above the belt on the case which is where the belteg mags are headspaced from. There is a tool from Inovative Technologies that sizes all belted cases for this issue. Great item if you are a high volume belted mag shooter. For a lower volume hunting only type use an occasional new bag of brass is cheaper.
Happy Shootin,
