The 338 PRO ran into pressure at 102 gr of Reloder 33 at 2956 fps with the 300 gr OTM bullets (tight bolt lift), I backed down a couple to 100 gr and an 18 round ave. resulted in 2860 fps, the bullets were not coated in that ladder test but will be revisiting that 100 gr RL33 charge with WS2 coated bullets next time, ammo was loaded to function in the 3.850" Accurate Mags at 3.725" coal
