I had the same pass thru experience last year on a very nice 8pt.Deer was about 45 yds.out.Standing broad side checking a scrape.Punched him just behind left shoulder in the crease.He took off like a scalded dog.Hit him about 15 min b/4 dark.I went straight to the impact sight.There were 2 egg sized blood spots and a tuft of hair about the same size.Had nickle to dime size blood about every 10 yds.or so.Then after about 75yds of that,nothing.Looked for about 2 hrs.No success.Went back the next morning and found him.He had gone about 250 yards and was piled up under a tangle of laurel.Bullet sized hole on both sides.I had hit him perfectly through both lungs.It was warm the night befor and I lost all ther meat.They group extremely well out of my Omega with 110 grains of t7ff but that deer did not go down like I like them to.I'll give a little on accuracy this year,back to Nosler partitions for me at about 1 1/4 to 1 1/2 groups. hunt4me
