Monos are “fine” and are definitely no worse then they were 10 or 15 years ago when the marketing hype on the outdoors channel was in full swing. They work. I use them in certain applications. Up close? Who cares. They kill stuff and don’t make a mess.
A lot of the popularity of products comes from the marketing machine behind it. Look at leupold scopes and Barnes bullets as prime examples. Are they the best ever? No, they aren’t, but they are marketing genius’ and just about every hunting show for the last couple decades had a guy with a leupy scope, leupy rangefinder, leupy binoculars, shooting a Barnes TSX. That’s where the majority of the hype came from. It wasn’t so much from guys using them and seeing increased performance, it was because “insert hunting personality here” endorsed them. And “you need a big tough bullet for big tough animals” per every gun writer ever. Monos dominated outdoor entertainment for decades
Bring the year 2024, or the last few years at least. “Long range” hunting and shooting is more accessible and popular now than it ever has been. It’s never, ever been easier to get into than it is today, and it will be easier to get into tomorrow than it was today. Think about all of the technology, the killer rangefinders that measure exact distances and angles that don’t cost obscene amount of money anymore, kestrals and similar, the numerous ballistics apps and solvers that are just a click on your smartphone away from being downloaded. Guys that wouldn’t dial a scope 15 years ago that were hitting the woods with a 200 yard zero and “X amount of INCHES of holdover at 300” are full on ballistics nerds today, and it’s easy as heck to become one.
Think about the free content on YouTube from guys like Cortina (and numerous others that have thousands of hours of free content and instructionals on long range shooting and hunting) that can legitimately take a guy from not being a shooter and not knowing a sizing die from a small pipe bomb into guys that can smack steel at distance and be able to load their own benchrest quality cartridges in their basement. Not unlike some posters here (you know who I’m talking about) these guys do all of the work and all of the research, and give it to the rest of us for free. Thank you internet.
As longer range hunting and shooting becomes more popular, monos become less popular. Due to external and terminal ballistics for sure, at 300 yards you can shoot an animal with *just about anything* for a projectile and it will die with little drama. BC’s don’t matter much either because wind is not a huge concern 300 and in.
As average shot distances grow, impact velocities gets slower, the projectiles that become more and more obviously the better choice are the high BC, violently and rapidly upsetting bullets.
Not only that, to be effective at long distances, you need to shoot a LOT. Why would I load and shoot Barnes LRX for example, for hundreds/thousands of rounds of practice a year at $1 a pop (current midway price for .30 cal 175 LRX) when I can get 168 ELD-M’s for literally half the cost ($.47/piece right now on midway).
If I go with the ELDM’s I’m out the door with a bullet with better BC’s, better terminal performance at distance, and to add insult to injury I can shoot twice as much in a year for the same money.
I’m not a mono hater by any stretch of the imagination. But it’s not hard to understand “why” with the high popularity of precision long range shooting and long range hunting today, they are less popular than they were yesterday.
