Here is a preliminary reply to the initial question, the penetration ability of the new Sierra Gamechanger. This evening I shot four different .308 165 grain bullets and one 130 grain bullet into 18" of soaked and densely-packed newsprint.
The Sierra Game Changer, 165 grains, .308 as stated, over 44.0 grains of AA4064, penetrated 15 1/2" and retained 136.5 grains. Nice mushroom recovered.
A 130-grain TTSX, 46.5 grains of IMR 4895, penetrated 16 1/2" and retained all of its weight.
A 165-grain Federal Bonded Trophy Tip, 44.0 of 4064, penetrated 17 1/2" and retained 156.0 grains.
The 165 grain Accubond and the 165 grain TTSX, both over 44.0 AA4064, passed through the 18" of newsprint and a folded saddle blanket and were not recovered. I had another 7" of soaked newsprint but I could not fit it into the fork of the tree I was using so I had to settle for the 18 inches.
All shots were from 100 yards.
Excellent report. Thanks.
