I see a lot of posts about bullet performance from close range. I've had a few failures over the years with non bonded bullets over expanding on deer and elk shoulders at close range. I've since moved to bonded bullets for anything inside of 300 yards and here's a quick test showing why. This isn't intended to trash any bullet brand or type, I hunt with all of the ones I've tested, I just want people to realize what can happen if the wrong bullet is used in the wrong situation. I shot a 140 Berger VLD, 140 Nosler Partition, and 147 ELD-M into a Ponderosa Pine round at 25 yards from a 6.5 SAUM to measure penetration and retained bullet weight. velocity was 3050 with all bullets tested. I know this is not the same as shooting flesh and bone but it mirrors my real life experience with each bullet. I've had a Berger completely fail on an elk shoulder, and I've had a 140 partition break the heavy shoulder bone on an elk (not the scapula the big --- bone) and pass through to the off shoulder. I hope this is helpful 140 Berger VLD, penetrated 7.5 inches, bullet completely disintegrated. 147 ELD-M, penetrated 7.5 inches like the VLD, found a little more bullet intact. 140 Nosler Partition, penetrated 13 inches, bullet was a classic mushroom. Left to right, 140 Partition weighed 97.3 grains 140 VLD weighed 9.9 grains 147 ELD-M weighed 21.4 grains just for comparison a 7mm 175 TSX weighed 160.5 grains, shot at 2900 FPS penetrated over 24"
