I agree with you sir if you are handloading it makes a huge diffrence. I am just thinking that to many people are beng led to beleive. You can walk into Dicks, Walmart, wherever and pick up a rifle and a cheap box of ammo and expect to get sub moa groups. Yes I have a couple rifles that I always got so-so accuracy with factory and switched to handloads and saw a dramatic improvment. The best thing I have ever bought was a OAL gauge. On top of handloading trigger time is very important also in getting those groups.
Here's the but. Alot of people don't handload, I have met a lot of dummies that think bore-sighting takes the place of sighting in a scope. Have seen countless people wanting to return a rifle because someone said they could get sub-moa accuracy out of the box. You look and they are buying the cheapest ammo money can buy. With good factory ammo I stand by my claim that I own three rifles that can shoot those kinds of groups. With handloads the number goes to 8-9. If you go to 5 shot groups the number is 6.
