Ruger didn't fix my revolver

think you might be en route to making your revolver shoot worse than it does at present.
It will not shoot worse. Reaming the cylinder throats to .4525 will only help when shooting lead. Will not help jacketed as much, except to lower the pressure a bit. Not only does reaming correct the throat size, it also trues up the throats. With my Vaquero, the group size was cut in half. With the BH, not quite as much, but still tightened the group. Also the leading was less. My reamer has paid for it self as I have reamed a couple of others for friends and 3 of the 4 cylinders of my two new flattop convertibles needed reaming as well.
 
You are fine reaming the throats to .4525
If you are shooting cast bullets, a tight throat will swag the bullet down to a size smaller than your bore. Depending on your load, and hardness of the bullet, the bullet may not expand back to the bore size for decent accuracy, and you may get increased leading. If I only had one Ruger .45 Colt, I would have sent the cylinder to Cylindersmith for reaming. I purchased the reamer because I have several, and they ALL needing reaming.
 
I have done my 45colts. I just used the reamer and a 1/2" drill chuck. Cut the rim and web off of a fired case and slip it over the reamer to help keep it straight. Use plenty of oil and don't push hard on the reamer let it cut.

Not to upset anyone, but I'm just curious as to why you would buy
something that you consider to be crap?

The answer is I've been quite happy with all my other Ruger revolvers, but I'm disapointed that they didn't fix this problem even when I sent it back.

My parts came in today. I'll try to make a video or take some pics of the process over the weekend.

The moral of the story is, if it ain't broke, they won't fix it.

My Vaquero has throats that measure .451, and it shoots .452 bullets (both jacketed and lead) just fine. Some fellars who shoot lead exclusively want their throats to measure .4525, but it's not required for the gun to shoot good, expecially if you shoot jacketed bullets.

And what did you expect them to do with a fixed, non-removable front sight? I filed mine myself to get it to shoot my load to point of aim. Different loads will shoot differently, and Ruger has no way of knowing what load you intend to shoot before they ship, or before you buy the gun. The fact that the sight was too tall is actually good. If it was too short, THEN you'd have a problem. Front sights being filed on a fixed sight SA revolver is pretty common.

Don't sweat the small stuff, and go enjoy your Vaquero.

Success!

Range report will take a few days.

For the record two chambers were .4510 and the rest were .4505
