John,

I have two DR's in .375 H&H belted. I load using data for the lower pressure flanged version.

I have had absolutely no problems with anything having to do with these rifles. It's only foolishness to shun a DR because it's chambered in .375 H&H belted.

This statement comes from somebody who considers himself somewhat of a purist as to DR's.

I would think any DR with rimless extraction should be carefully cleaned after the day's hunt with particular attention to the extraction pawl. Anybody can do this. But the admonition to clean daily applies to every firearm, and not just a DR with rimless extraction!
