Ive ran 350 Xs past 2700 fps. In my CZ (2,740).
My "hottest" load with Nosler 400gr. Partitions show 2,698 in my ledger for an average of 5 shots. with RL-25 and Fed. 215s.
My only cast load has been fired over 100 times and consists of a 375 LBT-LFN GC, 45 grs. IMR 4198, 13 grs Dacron and a std WLR cap for 1800 fps and 3/4 3 shot groups.
All loads used Norma or B.E.L.L. cases.
Dies matter and Ive had great results with RCBS dies. The Hornadys that came with the gun were horrible for neck tension and the seater was not favorable for the cast loads.
