I'd bet ya a steak dinner I can make a believer out of you if you want to spend a day at my place some time tuning your rifle. It'll have to be a Mexican steak dinner, as that's the only place close by to eat in my small town.. that has steak anyway. Not arguing or any of that. Just a friendly invitation to come to my place and do some testing is all it is. I wish it was indoors but it's not. But it is a nice shooting/loading room attached to my shop, with a good concrete bench, heat and a/c. Just bring your rifle and ammo. Again, just an invite. Would enjoy meeting and shooting with you. At the very least, you'll see the basis for my tuning procedure firsthand. It's just a method but is way more methodical than many use.
