Two more 77TMKs in the air, two more bucks on the wall for my daughters during the 2025 MT youth deer season.

My middle daughter (13) made an excellent, slightly quartering-to, 274 yard shot on this mature mule deer. He took a 25ish yard death sprint after the double lung thru-thru shot and piled up hard. His lungs were mooshy and the exit (side pictured) left plenty of blood on the ground.

My oldest daughter (15) killed this buck at 245 yards. He was quartering to us and she dotted him a bit high on the point of his shoulder. Dead on impact, he fell on the sage bush above him in the picture, slid down until his antlers dug into the dirt, and straight-legged-flopped his body over to what you see here. Zero movement after he came to rest. The bullet penetrated the shoulder, clipped the top of his lungs, and destroyed about 5 inches of his spine. A few fragments in the back strap, but mostly slipped under the goods!
I didn't take any necropsy pics this year, but the destruction of the soft parts of the first buck and the wound channel thru hard parts of the second were par for the course with the .223/77TMK combo.
My girls have taken 9 bucks to date with 11 bullets in the last 6 years. One of the extras was a follow up hit on a heart-shot deer that kept his feet long enough to get shot twice. The other extra was a follow up hit on a deer that was falling down from the first round. In total, I'd estimate that the 9 deer have traveled less than 80 yards combined. And they both mentioned this year that they watched the impact and knew they had punched their tags! The .223 is SO shootable!!!!!
My oldest daughter also pointed out, on the ride home, that the 2 "misses" (her first 2 years) were before I had a suppressor for them to hunt with. Since then, they are 100% on 1 shot kills.
