I don't think I would interpret Oregon rules to include 209 primers (nor Idaho rules) but that is no great loss, IMHO. The use of 209 primers primarily came about because of the development of pellets and their being harder to ignite. A great deal of effort and innovation has been shown in trying to REDUCE the flame from 209s.

For my use, the RWS 1075 caps have proven equally reliable and produce great results. My most accurate rifles use the caps.A properly installed #11 cap makes a very good moisture seal. Damp powder would be much more a problem.

I truly like the Whites and recommend all but the Thunderbolt model. The Ultra Mags are a great value, again IMHO. But if you want to buy a Black Diamond, I've not read too many negativesabout those. Mostly they are reputed to be very good rifles. The QLA section of the TC barrels can make conical accuracy an "iffy" thing though. Many TC barrels shoot much better with the QLA removed.

Still want a Black Diamond? If so, check with [email protected] (.50 blue/camo for $145, XR .45 blue/black for $135, XR .45 SS/black for $155).
