Like many, I've used a bunch of different bullets. Some worked well, others not so much. I've seen Noslet BT's from a 243 work great on deer shot in the ribs and I've seen BT's blow right the eff up on a mule deer shoulder from a 7RM. I used Partitions for a long time with pretty good results except two 375 300 gr NP that got stopped by a big bear spine and while the bear died I kinda thought they should do better. I've seen lots of cup and core bullets kill animals but not that efficiently and for the most part lead core bullets throw a lot of shrapnel around in the meat.
I haven't tried every bullet out there of course but a long time ago I decided I didn't want a bullet that worked when everything went perfectly- almost any bullet will do that- I wanted a bullet that will work when things go wrong and shot angles aren't ideal.
I used Barnes X bullets and yes, they could be finicky to get to shoot well and back then mono bullets were kinda new so most people including myself didn't really get the idea of dropping down in bullet weight to help the X bullet do it's thing so while everything I shot with them died sometimes it wasn't a spectacular kill unless hitting shoulder bone.
TSX, TTSX and LRX totally changed that and that's mostly what I use for a couple of reasons- they get the job done from any shot angle and they don't throw shrapnel through the meat.
I actually really like the performance of the Nosler Accubond, I think they are far better bullets than partitions because they are more accurate and the bonding keeps them together better than the H style partition which loses virtually it's whole front end and I've recovered them with no back lead core as well. If there were no mono bullets I'd probably use Accubinds and just deal with the shrapnel.
While most stories about mono bullets "penciling through" are just people repeating stories they have no personal experience with, I also have seen first hand accounts of it and I don't doubt it has happened, especially in the days before Barnes stuck a blue plastic tip on the bullets. Hollow points of every make have done weird things when they hit bone and closed the tip so expansion was not optimum.
On the same note there are lots of first hand experiences with non mono bullets failing, sometimes spectacularly failing. Don't forget that the Godfather of Premium Bullets- Mr Nosler himself- created the partition after multiple standard bullet failures on an Alaskan moose.
Myself and my hunting group has had absolutely great results with Barnes TSX, TTSX and LRX bullets for many years using cartridges including .223, 243, 260, 6.5 PRC, 7-08, 7RM, 308, 300magnums 375 Ruger and etc etc. Killing deer, moose, sheep, goats, elk, black bear and grizzly. The few bullets we've recovered usually look like a Barnes advertisement with perfect expansion and penetration. Opening the chest cavity often reveals massive damage, indicative of both velocity and expansion. "Lung soup" as Bartell and I proclaimed it after gutting one deer.
So I'm never going to be convinced by someone with no personal experience blabbing away about how modern mono bullets penciling through is "known issue."
