As luck would have it I had a last minute change of guns before a cape buff hunt last October. didn't have much time to find ammo for 375 Ruger and bought 300 gr RN Hornady ammo. smacked a good buff broadside at 70 yds. hit him two more times in the chest as he ran out (PH said they were solid hits and I use an Aimpoint red dot so staying on target is easy). he went about 200 yrds.....when we dug out the bullets there was not much left..measured one at 142 gr! I know these are not the best expanding bullets but to hold less than half of original weight...something went wrong. any other experiences with these bullets? heading back to Zim in May for buff. Already testing Barnes TSX and Hornady DGX bullets.
