Replicating a factory load

[whoami-72]

Hello, I'm still working on getting back into reloading and have dumb questions.

The Hornady superformance cx 150gr ammo shoots really well out of my rifle. If I were to try and reload to copy it, should I expect to get similar results by copying the seating depth and adding powder until I get the same velocity? I understand it may not be exactly the same but figured it ought to be pretty close and a good place to start. Anything else I should try to copy it better?

I'm using norma cases, cci primers, and staball match. The bullets would be the same obviously.

I’ve often wondered if Superformance factory ammo actually uses Superformance powder.

The version of Superformance powder we have access to might be the same powder used in some factory loads but definitely not all. Superformance factory loads are different powder blends, supposedly 42 of them. I could be remembering it wrong or out of context but pretty sure I read somewhere that the retail version of Superformance is blend b.

What you're doing is definitely a good starting point. You might pressure out before reaching Superformance velocity but that may not result in different accuracy. I'd see how it shoots with your current components before introducing another variable.
