Yes.

I have fired them in one of my DR's - al beit at the request of Geoff as we needed some recoveries from the NT fired from a DR.

Now, I am dead against using mono's in a DR, but I trust Geoff and Graeme Wright and had carried the Hydro's before during development for a 375 Bolt so knew what they were and how built so didn't have a problem using them in my 500/465.

I also believe someone else in Tas used them in his H&H 500/465 as well.

I'd be less concerned by the "special blend" and more concerned about the design - ie the bands since the main part of the bullet doesn't touch the rifling.

I'd use them again, without a problem. I don't have a problem using Woodleigh SN, they all kill.

Hope that helps.
