The last couple of years I've posted some results of the terminal performance from the cartridges I've seen used this hunting season in a effort to add to the collective body of knowledge.
You can find the previous versions HERE and HERE
So in the similar vein to previous year.
300WSM/ 180 Accubond- I took four animals this year with my pet Nosler .300WSM and the 180gr Accubond bullet. The first was a small cow caribou shot at a estimated 40 yards, one shot- bang, flop, DRT. Couldn't be more pleased. Despite nearly full muzzle velocity at impact the bullet did not fragment. Caribou number two was a middling bull shot at a laser ranged 255 yds. One shot broadside and the bull collapsed in a heap. Everything forward of the diaphragm was soup. No bullet fragments were found. Caribou three was a large cow shot at a laser ranged 345 yds. I shot twice and hit both times in the low lungs. One of the shots shattered the breastbone. Again, no fragments or bullets recovered and minimum meat damage. The fourth animal was a unique experience- a wolf shot at an estimated 20'. Shot twice- once too far back and once in the nose that exited below the pelvis- pelt damage made my taxidermist smile at his hourly rate. Not recommended for that purpose- but the encounter wasn't exactly planned (or even desired). The 180AB might be the best general purpose bullet for the 2800-3100fps .300s like the .300WSM, .300WM, .300RSAUM, .300RCM, .300H&H and high performance .30-06s.
300WSM/ 180 Federal Soft Point- this is most likely a conventional Speer soft point bullet. Two shots at a middling sized cow at a laser ranged 250yds. Both showed good expansion and the caribou expired on the spot. This is a good economic load for open country shooting at deer, caribou and similar critters.
338WM/ 180 Accubond- I saw two caribou shot with this load this year. Both large bulls. One was shot at truly long range- 400+ yards that needed substantial follow up. The tough Accubond in .338 didn't really expand well. The second was shot at 80 yards. The hunter fired three times although he first hit was totally fatal. No fragments found, even on wound channels that contacted bone. The tough Accubond is perfect for this cartridge.
7-08 Remington/ 140gr Federal Fusion- this load accounted for two caribou. One a middle sized cow at 100 yards. One and done. Good expansion and exited. The second was a small bull shot at 55yds. Two shots- the first a quartering to that hit slightly high, contacted the spine and tracked under the backstrap and put the bull down. The second was a finisher shot at point blank a few moments later. The first bullet was recovered as shown below. These expanded very well at closer range with higher impact speeds which validated my theory from last year's longer range disappointment. These would do very well at typical deer ranges on deer sized animals. For longer ranges, I'd think a softer or faster bullet would do better.
