I haven't been on here in a long time but though I'd share some pics and info.
Both deer were taken in West Tennessee with a CVA Optima .50. The buck was taken using 100grs of pyrodex powder and a 245gr power belt. The power belt left no blood trail whatsoever and if the buck had ran into the woods may never had been found, luckily he ran across the field and piled up in plain view due to the double lung shot.
The doe was taken by my 8 year old son for his first deer. it was taken with 150grs of pyrodex powder and a TC 250gr sabot, blood everywhere, as my friend Doug would say "Stevie Wonder could have followed that trail". It only ran 80-90 yards before piling up even though only one lung was hit.
Both deer were shot at about 60 yards.
I'm not sure if the massive difference in wounds was due to more powder (higher velocity) or the different bullet.
Rifle season is now open so I'll have try try some different things next year.
