Do lee dies suck?

[SB]

Can you take one of your sized cartridges from your rcbs 308, lube it, and run it through your lee sizing die and see if the Lee sizing die is off?

Are you using a chamber gauge to check the sized cartridges? Jim

I will do that.
Got chamber gauge on the way. Been using rifle chamber.
30.06 and 243 dies work fine, but the 308 gives me fits. Which is why I gave up on it several times.
