Quote – “Is there a place you can go to get factory load specs? “

I think you can get the bullet weights and velocities for the cartridges from the companies web sights (or maybe off a box of their ammo). If you’re trying to get the same velocities with the same bullets then all you need is a chronograph. I do this in some of my ammo for home defense because the speeds that the factory loads at are probably good for the type of bullets they’re using. In my case Speer Gold Dots. At inside distances you probably want speed more than accuracy (most loads are accurate enough for 0 to 20 feet). If you want the exact components that the factories use I believe the posters above mine have explained why you won’t be able to get that info.
