The Trophy Bonded Sledge hammer was high tech 20 years ago.
Too many have bent like bananas inside of buffalo.
Their meplats are just a little too small to make them as stable as the CEB Safari Solid, North Fork FP Solid, or Barnes Banded Solid solids.
Also, no FMJ is a solid solid, whether brass or copper-washed steel "encapsulating" lead or tungsten cores.
Tungsten cores sometimes penetrate the FN meplat and leave the encapsulation behind.
Monometal solids with driving bands sized 0.474" are easier than Woodleighs on the barrel.
CEB brass and North Fork copper band structures are easiest on barrels.
North Fork gives the greatest variety of 500-grainers, SSP, CPS, and FPS.
Or try the CEB 500-gr Safari Solid and 470-gr Raptor/HP if your DR regulation allows it, many do.
