What makes a gun accurate?

random things touching the barrel degrade accuracy (for example if you have a non free float rail and rest it against something it can slighltly shift the point of impact). Thats just part of it though.

What this >>35116576 anon said, as well as wind, humidity, rifling of the barrel by 1/64th of an inch compared to another, rain, snow, sunshine, shakeyness of the shooter, difference in height from one iron sight to another, not to mention the round itself. The round has powder just ever so slightley off from one another, especially in hand loads. Factory rounds are a little less likely to be different, but every nanoinch or grain of gunpowder that is off from another could mean the difference of an inch to a foot in one direction or another.

Its also a combination of all these things that make an SKS apart from an AK-107 in terms of accuracy.

99% of it is about consistency. Does the rifles action lock exactly the same way every single time? Does it chamber the round the same way every time? Is the chamber "tight"? Does the trigger behave the same way every time? Is the scope mounted on a completely secure surface that wont shift at all during firing?

I also forgot to mention what the rifle is made out of. If its sheet metal like an AK, its less accurate as on thats made out of steal, like an SKS. Or stamped aluminum and steal, like an AR10 to AR15. which brings up another point.

I'm purely talking about the physical characteristics of the rifle and only the rifle.
Based on what has been brought up so far, we have twist rate and barrel contact as limitations. Is that really it?

Thinking of getting into precision shooting, I am aiming for 1600 Yards. Considering that I will need:

>jig and press $1000 for a good one
>bullet, powder and cases - should be cheaper but still expensive for 6.5CM
>good scope $1500

With the gun I am looking at a 5k platform. Would it really matter in the long run if I were to buy this over a RPR which is $300-400 less? How much of a performance increase can I get out of the Tikka?

Rifle: Rifling lands, crown, consistency of pressure (or lack of) on barrel, consistent level of carbon fouling in barrel (my barrel is consistently 40ft/s faster when I run a dry swab through it)

Cartridge: Neck tension of brass on bullet, powder consistency, bullet weight, diameter.

Powder: Temperature sensitivity, optimum load development (barrel is at peak or bottom of oscillation when bullet leaves it).

Here's a 13 shot group with my Tikka CTR 24" 6.5CM. Did some load development with RL-16, Nosler RDF 140's and Lapua brass (neck sized) to 41.7gr. Each shot was roughly 10 seconds average between, so barrel got pretty toasty. There's a few 308 holes from my buddy that was painting all over my target trying to get his Ruger GSR to zero.

Fun tagging a 8" triangle at 800 yards consistently. Whittaker guns should have the same rifle as mine at ~$830 and Vortex PST EBR2C scopes are better than I could ever need. I would recommend a Redding T7 if you don't mind spending the $ on it. I just got a second Chargemaster 1500 so I can bust out fast, precise loads (lol).

AKs are made out of steel you illiterate retard.
