Last year I tried the 210 ALR in my custom 300 win mag. Awful results. Nothing shot better than 1.5moa, and this is out of a proven sub 3/8 moa rifle. Let's be clear up front I am not trying to bash the ALR. I am just reporting on the results I have had. I sent the remainder of the box I had left for free and paid for shipping to another forum member who said he would tell me how they shot out of their gun, and never heard a peep back from him even after several PM's asking. My thoughts are that I got a bad box of bullets, probably manufactured at the very end of a production run and the tooling was just worn out. Nosler has basically no process control within their manufacturing process from an engineering perspective, so chances of getting a bad box of bullets is higher than some other bullet manufacturers. I would typically play the odds and just buy another box, and they likely would have shot great. But you just cannot get those bullets, so I have given up on the ALR and moved on to the Berger 210 Hunting VLD and the 215 Hybrid, both with excellent results.
Below is a picture of several 210 ALR's recoverd from the dirt backstop behind my 100 yard target. Muzzle velocity on these rounds were in the low to mid 2900 fps range, shot at about 5700 ft elevation. Dirt was normal/dry hard packed soil mixed with rock. Weighing the bullets and 3 of them came in between 65 and 75 grains, 1 of them weighed 115 grains. This is in dirt and not an animal, but shows that they are going to have a tendency to explode up close as they are not as durable of a bullet. A 200 Accubond (not LR) I shot in the same shooting session at about the same muzzle velocity weighed in at 170 grains and displayed a much better mushroom.
Kind of like you mentioned, maybe a triple and not a home run, but a step in the right direction. Even then, I would have to see some very compelling field reports of deer and elk shot up close with the big 300 magnums to make me switch away from the Berger 215 Hybrid.
