What BS? I'm just trying to clear this up. I feel like maybe both of us are misunderstanding each other. I mean no disrespect to anyone. It's my belief Erik started making his videos with the main intent to help the shooting community. That's what I take away from it first and foremost.So you need to shut that BS down.
And I completely agree with you that there are TONS of variables at play. I've discussed that numerous times in numerous posts and comments in this forum. It's very difficult to get ahold of each variable and eliminate each one. I personally have found by doing certain steps, and doing them a certain way, has greatly helped reduce variables though. Annealing, and annealing a verdin way, is merely one way to reduce certain variables. There are still many more at play though and if you're not taking steps with those too, no, you won't ever be able to shoot the difference. All those variables compound together. The shooter is always going to be the biggest variable, and the environment might be the next biggest.
Either way, I'm not trying to stir any pots here and I didn't mean to offend.
