Here's a free bump and a vouch for the product.
When I finally found my Whitworth .375 H&H, I picked up a couple bags of R-P .375 cases to get going with load work. Now, I process and measure a LOT of brass. And I carefully went over these R-P cases and was blown away by their quality and precision. They were Lapua-like. Very consistent weights and far more importantly, almost all the neck walls having less than .001 thickness variation. I've no idea if I just got an exceptional run of cases or if R-P's .375 H&H tooling turns 'em all out like this, but I couldn't be happier with mine.
