Thread: Variables affecting precision

Years ago I read a very interesting article where the authors started with a sample of Remington Model 700s IIRC.

They went through and validated the grouping on each one. Then they carried out specific upgrades on each one and re tested group sizes post upgrade.

From memory, the two most dramatic improvements were the trigger upgrade and polishing the barrel. I read it in a magazine in a hut I think, and haven’t been able to find it online.

Your diagram is a similar principle. I don’t know if it’s dimensions and weightings or listed factors could ever be perfect as these will vary from shooter to shooter and also from rifle to rifle, but it is an excellent visual for how to think about the factors affecting accuracy.
