[QUOTE="rocketman, post: 3947453, member: 24956"] I think this video has some poor advice. First off, finding your lands by jamming a dummy cartridge doesn't work well and can give false results. The bullet is being pressed into the lands, and as he admits, risks pulling out of the case a bit on extraction. This can give a false, excessively long measurement. I used to struggle with this method in various forms (tight neck, loose neck, split neck, etc). I had difficulty getting consistent results. When I found out that one of my (supposed) 0.010" seating depth loads was actually jamming bullets I finally bought the proper tools. You need a Hornady bullet seating depth gauge and a fired case modified by Hornady (or a machine shop) to thread on to the gauge. No exception. It only takes a few minutes to use it and the results are consistent. He makes the point that seating depth is a safety issue. He says distance to lands doesn't matter. Then he goes and attempts to find the distance to land and sets his seating depth for his load. I thought that "didn't matter"? Then he makes assumptions about his throat wear based off accuracy results. And he's going to keep seating the bullet further out, chasing the group. Is he going to recheck his land measurement at some point or does he really not care anymore? The load I mentioned where I was jamming my bullets due to a bad measurement was my most accurate load. If I followed his advise, I'd still be chasing the jam! I seat 0.010" off the lands to start combined with collect neck sized cases separated by neck runout. I then work up the powder load until I hit a sweet spot. I recheck distance to lands occasionally as a safety check or when changing bullets. [/QUOTE]
