Woops--You're right, Miller. Rocketman was in fact agreeing with me on the pricey nature of retesting LUP-rated loads. We all make the occasional mistake . . .
Can't comment on the 3 ton proof aspect, Miller, but the reason I used quotes is because it's straight from the email I have from the Brit proofhouse. Straight from that email, the Brits measure with crushers but call those measurements "bars"--so you've got the same old LUP vs psi conversion to make. Which the proofhouse was kind enough to do for us.
