Does the army give every soldier 10 packs of different ammo brands and ask them to figure out which one their rifle likes best?
Well, NO; You're comparing Apples with Oranges.
They [Army] have a vastly reduced number of projectile options, for starters.
And because they dont have the time or resources to burn that much ammo..
Have a think about if you buy 10 different boxes of sporting ammo at your LGS for your rifle; good chance there will be 6 or 7 variations of projectile style, weight, and Muzzle Velocity in that mix.
Conversely, Army will have one or two options for the front-line standard-issue rifle in that calibre.
But they do have teams that will have evaluated the ammo that is the 'Best Fit' for the standard-issue rifle.
It wont perform the best in EVERY rifle issued to front-line troops, but it will be the Best Fit for what the army have available.
And producing ammo for a battlefield, is a different kettle of fish than producing sporting ammo.
I'd expect it's a VERY different story if you asked the same question of any of the army snipers; pretty sure you'll find the sniper himself has worked through what performs the very best for that particular firearm, and very good chance he's been involved in manufacturing that ammo.
Every rifle ever made will have been machined and assembled with very slight differences in tolerance.
And a number of current manufacturers have gone through periods of VERY spotty Quality Control in their sporting rifle lineups in the recent past.
[Remington had this issue some years back; I lucked out with an absolute pearler of a Rem700, but 2 of my mates who bought the same rifles at the time had nightmares in getting them to shoot straight.]
Another point will be when you are comparing like for like.
In the case of the Howa 1500 rifles, as far as I know, the .223 has had 3 or possibly 4 revisions to the twist rate in the barrels.
Each change in twist rate of the same model of rifle, will change the way the same ammo performs.
Just after I bought my first .308 in 2012, I bought a batch of 200 Hornady Match 168gn BTHP ammo, as well as a batch of 200 Highland 150GnSP.
Most of my shooting at the time was fairly short-distance(>100metres), and I would have said that both batches were performing comparably.
I didnt use all of the Highland ammo up, and when I went to use it in later years, I was much more comfortable with 150-300 metre shots.
Well, the Highland turned out to be horrendous for distances past ~100 metres.
I ended up pulling the last 5 projectiles, and I could see the powder used was a cocktail of different types, and didnt look to be the same ratios in each shell.
Mentioning this to the LGS where I bought them, he said my comment was echoed by a number of buyers of that batch of ammo.
So, as your LGS has advised, I'd be trialing what ammo your rifle performs best with.
I think he's recognizing the fact that every firearm produced, is somewhat unique.
That uniqueness becomes more obvious, as you push how far you want to shoot accurately.
QUESTION:- What would you do, if you just bought the one box of ammo, take it home, and you find it shoots like crap?
Before you decide the rifle is a dud, wouldn't it make sense to try some other ammo to see if the issue is replicated across all ammo types?
That way, you can explore what you need to do to fix the rifle(new barrel etc).
But without trialing a few brands of factory ammo, you wont ever know if the grouping from your first box, is as good as it gets.
Reloading(for me) is for multiple reasons:-
1). Availability - Most factory loads that work best in my situation, are hard to source where I live. If I stockpile my own consumables and equipment, I can load up a new batch whenever I need to.
2). Consistency - As the Highland ammo taught me, if I can reduce as many variations in the mix, then I'll have a more consistent result in the paddock.
3). Satisfaction - Batches of loaded ammo all ready to go, is a pleasing sight, and makes you consider reloading another batch.
4). Matching the rifle - As your LGS has suggested, dialling in the best load that suits my rifle.
5). Cost - For me, reloading is fairly cost-effective most of the time. Though, some of the ADI ammo is hard to pass up, and the brass is pretty good as well.
6). Understanding what your rifle is truly capable of - Nigh impossible to do solely on a diet of factory ammo.
I have a lot of money invested in equipment and consumables, so mightnt be worth it for someone only shooting 150 rounds a year.
But I think your LGS has given you solid advice; if you arent going to reload for it(work up best load with what you have available), then trialing out an assortment of different ammo will give you an idea on what works best in your rifle.
My 2 cents.
