Ok new problem i have a 10.5 solgw 300 blk and it is shooting big groups like anywhere form1.5-3 moa at a 100 yards. Ik im cable of 1moa with my 556 12.5 I shoot 110 gr hornady vmax for hunting and 125 gr freedom munitions/sig sauger rounds for practice and plinking. Is it the round or is there some secret im ignorant of? I’m still trying to learn about 300 any help be appreciated.
Does the accuracy spread over time (like as the barrel heats)?
Does it do this with all ammo.
Honestly man, in tinkering with scoped AR's for 20 years and trying to squeeze every bit of accuracy from one to the other this is about all I can offer in terms of consistency in general:
- Most decently built, free-floated barrel AR's should be able to print a 5-round group under 2 MOA (probably closer to 1.5) without much difficulty with at least some form of high-quality ammo (though it may not be the flavor you want it to be).
- Deviations can come from some wild shit. Dynamics of pressure on the rail (bipod load) to muzzle devices to altered feeding dynamics from magazine lip spread just to name a few can tolerance stack to add some frustrating deviation to groups.
- Barrels and by extension upper/rifles themselves have entirely unique characteristics. Even when using barrels from the same production runs or from very tight specification parameters, they can behave very differently.
- There may be teething issues say with gas port burrs or erosion settling in or things of that nature that can lead to inconsistencies.
