20 years ago when I first bought my win model 70 300WSM Coyote I originally started shooting 150 BST. I thought they were cool looking. They were fast(3350fps), they were accurate, and they put deer down fast. They also depending on my placement damaged alot of meat. Some went all the way through, some made excessive damage on the entry, some came to a stop inside, but they always reeked havoc. Shots were probably all under 150yds. Then I went elk hunting(the reason I bought a .30 cal in the first place) and started shooting 180gr. failsafes(still have a few). They were very accurate, but I cant remember if I ever killed anything with them, maybe a deer, but not an elk, I didn't take the shot when I had the chance, I was waiting for something bigger, and I still am. Then I decided, I would shoot 165gr. BT and/or AB, a happy medium between elk and deer sized game, without having to re-sight in my scope for a different weight bullet. Then I built a custom 260AI and no longer needed a .30 cal for deer sized game so I switched to 180 AB with no intent of ever shooting light weight bullets again in my 300WSM, and so far haven't. Bottom line for me is I've never had any issues with Nosler AB, BT or failsafes, coated or otherwise, of the shelf or handloads, they've all shot accurately and performed as I would have expected. I'm not trying to bragg up Nosler, that's just been my experience. I shoot bergers in my 260AI and my 243 win.
