[QUOTE="bigngreen, post: 1266513, member: 13632"] There are a number of what is being called bore rider throats, some have a more complex geometry with differing angles and some are just cutting two hight lands for a distance but the same lead angles. They've been in use best I can tell since the 80's. It's an interesting thing, I've seen a number of what would be a moderate chambering toast the throat out in very low round counts. Bench guys have been playing with it of and on, it does change the pressure curve but most I know really don't end up running much faster just with better brass life but shorter accuracy life than a conventional throat. I've used them in very limited situations, one would be a round that is not going to be hard on throats but it needs a little pressure taken of the front end to run, situations that just let it run a little easier at the same performance. There is no way I'd use any throating strategy other than normal for something that is a throat burner anyway, the throat will wear more even for more rounds with a conventional throat. [/QUOTE]
