I'll be interested in what you find out.  I personally don't believe in them much although Eric is a terrific shooter, and I've heard of some testimonials too.  My own take (worth 2 cents btw!) is that for many rack-grade barrels it may be helpful, but the method I use is to (1) find a better barrel, and (2) use load adjustment (to find the MV) and varying seating length to find the "node" based upon timing of the barrel's length.

O, and for what it's worth an article on accurate shooter/prs blog bulletin, that said for most bullets, seating 60-100 off the lands is not necessarily the "Best" group, but it is one where sub-0.75"-ish groups are attainable for longer than the 100 or so rounds it takes to move your throat off of that "riding the lands" method... Like I said, my opinion there.

But interested, yes, in what you find out.  If something helps, then good for you!

Well I screwed up when having the barrel made (no threads ) and there is not a place near me to have it done so may be a while BUT the plan is to try it with factory ammo then a worked up load so we shall see .
