Use something like full strength Simple Green, Murphy's Oil Soapor Lestoil-type soaps to remove the packing grease inside the bore. Then rinse it good with rubbing alcohol- then dry thoroughly before oiling. Like Phil suggested, shoot a minimum of one box of full-fledged conicals to smooth the bore of any tiny microscopic burrs.

So in this hot weather, your first typical outing at the range will not be sighting-in -- just getting comfortable with the new rifle & watching it slowly break-in.

Some break-in periods last 60-80 shots with today's inlines. Plastic sabots delay break-in -- so that's why it's important to shoot conicals first.

You got a nice rifle there- even though those red primer carriers are a nuisance to some. I'm still waiting for the first poster to show me a custom NEF - with the wood stock and stainless barrel. I have-yet to see one.
