Thanks Dale, I guess the extractors will be much of a known quantity. I'm a bit of a breech & action man myself, you can read into that what you will

, I guess in automotive terms it would mean I'm as interested in the engine , transmission & chassis as the bodywork, sort of beauty is as beauty does but thats not to say I don't appreciate the exquisite beauty of rifles like yours. Those are three beautiful rifles you have there, 8x57R is a really nice caliber to my way of thinking. It will be interesting to see how they respond individually to loads & whether or not you can get a one load fits all three.
