Re: Are custom actions that much better
One big difference is resale value. A $400 Remington action with $200 (or more) worth of smithing is usually <span style="font-style: italic">still</span> a $400 Remington action. You will never get the cost of the blueprinting out of it when, not if, you decide to sell it. Granted, since you're getting the blueprinting done for free, that may not be a concern for you.
And I think that there are some accuracy considerations to consider with custom actions. I'm talking about things like a longer threaded section that will support long, heavy barrels better than a Remington, and the fact that custom actions are machined <span style="font-style: italic">after</span> heat-treating, rather than before. You end up with an action that sits in the bedding much better than a banana-shaped Remington action ever will, even after blueprinting. This is especially important if you're not skim bedding when using a stock with an aluminum bedding block. The differences may be small, but they <span style="font-style: italic">do</span> exist.
