I almost always prepare the bullets with checks and pre-size before coating. The only exception is if the gas check shank is too small for the checks I'm using, then the PC helps make them fit better.

As to the original question, I've used Hornady checks and some from a fly-by-night vendor made from soft, uncoated aluminum, both worked very well and if powder coating over them, I couldn't tell any difference in accuracy even with a pretty hot load.

Aluminum or Copper? Now finally in the 21st century you can make your checks last twice as long with the invention of the half check bullet.

Great, and now there will be a debate on the merits of indexing the bullet in the neck and chamber to best account for the planets spin effect and whether or not you have to reverse it in the southern hemisphere...

They did, and it was truly amazing they worked perfectly well in Europe and round the Mediterranean, and even in the air when sideways, upside down, and when turning clockwise or anti-clockwise.;)

I'm feeling less snarky now .......

This opens the question , does the "spin drift" of a left hand twist change the corialus effect at long range ? Would a guy have to hold more drift shooting north than the same cartridge etc with a right hand twist ?

no cause it'd be dropping in the same direction the earth is rotating.
the right hand twist tries to fight the planet and of course will lose sooner so it falls to the ground faster.
you'd be better off with the left.
left drift, the target will be further away when the bullet gets there, right hand drift just causes a miss because it's aiming at a target that ain't there nomore.
but what do i know my range faces south..
