I don't think using more powder is the fix. I use 100 grains in my remington and it shoots fine. I would look at the type and size of the projectile. I was having a problem with not getting pass through shots shooting a Hornaday 240 gm sabot. I switched to a 300 gm Hornday XTP and it was problem solved.
If you tracked a deer over a mile it was probably a flesh wound anyway. Just MHO
If your to busy to go hunting, your just to busy.
