I heard there is a 8th edition of the hornady reloading book but seems like the older calibers have been left out like 30-06, .270 win and a few others.
This was just a thought and wanted to see if anyone was able to duplicate the results from the factory ammo.
If anyone has some load specs for a .270 win with a 130gr. SST it would be much appreciated. I have reloaded some with IMR 4350 but it doesn't shoot nearly as well as the superformance.
Thanks,

I think what your asking is about the powder? What do you want to duplicate, hope your not going to identify the powder and use it with the bullet's you pull? Definate no-no! Hornady has access to powder's you can't get.
Duplicating factory ammo is no big thing but what you want to do is find out the velocity and then match up to a bullet and powder combo that does that. To do this you'll need access to a chronograph. I wouldn't try to duplicate factory ammo, if you have a bullet you like develope your own load.
The bullet and cases are easily duplicated, just buy them. The primers may be a bit harder as you don't know what primer they use, just pick a primer and test them while shooting. The powder? Again, forget it!
