Re: Newb and a Lee Collet die
Just a thought but you might want to mic the mandrel, sounds like it's over sized, careful about the pressure your applying, you'll squirt the die guts out the top.
Keep in mind the animals we shoot for food and display are not bullet proof. Contrary to popular belief, they bleed and die just like they did a hundred years ago. Being competent with a given rifle is far more important than impressive ballistics and poor shootability. High velocity misses never put a steak in the freezer.
