Dear A1:

Your contention seems to be that I have not already done so. It is considered polite for newcomers to a site to review previous posts to avoid needlessly rehashing old ground, or worse, making a statement such as yours. If you had, you'd have known that I've already done so. If fact, we covered some of it in your own string "Re: chrono of factory loads", and it's been a common subject here for years.

I'm far more familiar with the OSR problem, and was introduced to it far earlier, than I would ever have liked to be. I've seen a lot of doubles with it. And yes, I've ruined one myself, although, luckily, it wasn't mine. No, I haven't fired any monos in a double rifle since, and never will. I don't have to get bit twice.

In the interest of helping other DR shooters to avoid the same costly error, I am always more than willing to provide details when the issue comes up. In your case however, feel free to dig them out of the archives yourself.
