I don't know if this is the right section but since all I have ever owned is rimfire guns here goes ....

Why does a gun shoot some ammo better than others ?
When I look at a 22 bullet they are all the same pretty much in looks ... some may be hallow point, others not but size wise they are the same.
I understand that inside the casing they are different in load.

As none technical as possible .....
The bullet goes from the mag into the chamber, you pull the trigger and a firing pin hits the rim of the casing and it fires, the lead bullet goes through the barrel and hits the target wile the casing is ejected from the chamber and a new one loads ... if its automatic.

So why would one make of bullet shoot different from another make ?
And why would my gun like one make of bullet better than what your gun might like if we have the exact same gun ?
 
weight of the bullet
type of powder (different burn rates)
amount of powder
shape of bullet

how clean your barrel is
how hot your barrel is

Each cartridge be it rimfire or centerfire is loaded with a select powder from the manufacturer. They have different burn rates. Each manufacturers bullet are also typically quite different. A slightly change in ogive (tapered body profile) changes the aerodynamics of it. These slight differences also react differently to the harmonics (vibration characteristics) of each rifle barrel. That is as simple as I can explain it.

Ok but that dont explain why if me and you both had a 10/22 why would the same ammo not shoot the same out of both our guns if they were both clean.

If that was the only case we should be able to post on here ... all 10/22 owners buy such and such ammo because 10/22 shoot them best.
 
Well, the most obvious would be that factory actions and barrels are never made identically, so they won't all perform exactly the same with the same ammo.... especially 10/22 barrels
 
I have 3 Mossberg model 151s and each liked a different ammo. One the Winchester hollow points shoots great and another the American eagle solids and the other a Dynapoint solid. I chose which ammo created the best grouping after shooting many types of ammo. The 333s by Winchester proved the best . My 3 Marlins were the same...but all seemed to like the cheap $20 dollar / brick Western brand by Winchester.

No two barrels are identical, nor the rifling twist exactly the same, and ammo manufacture specs seem rather loose, so bullets may not be identical nor the powder load, thus accuracy varies.

Manufacturing tolerances are loose enough that no two guns come out of the factory the same. There are just enough differences to make two identical models shoot slightly different with the same ammo.

Also, basic ammo is produced as cheaply as possible, so the quality control and consistency of powder composition, burn rates, bullet dimensions, etc. are not as good as they could be. Even high quality match ammo has enough variation from batch to batch that serious competition shooters will try to buy only certain batches that they know their guns will perform best with.

think of your barrel as a tuning fork, different loads hit that tuning fork slightly different.every barrel has a minutely different metallurgical structure making it a slightly different tone of tuning fork.
