Thanks guys,
What i have gather here for myself is this....
I'm thinking they were shooting a lighter weight bullet in a fast shooting gun.The bullet is mushrooming correctly,but loosing it's energy to quickly.
Shooting a heavier bullet adds enough energy for the pass throughs.Which i like for easier trailing,and i just feel better about getting complete pass throughs.

That .44 cal sabot i use was 240 gr.If i had used a 385 gr conical im thinking i would had a pass through.



It's not how big the Deer,But the size of the experiance that matters!!
