[QUOTE="Rardoin, post: 1947118, member: 114954"] I compete with Erik in F-open (slow fire 20 shot matches at 600-1000yds). Our precision needs to be .5 MOA over 20 shots to be competitive at the big matches and nationals. Erik is a bit outspoken but is a great guy and an outstanding shooter/wind reader. He does not mind controversy, obviously:) While he is bold at stating his opinions they are not given flippantly but born of solid experience. His video titles are appropriately bold and are designed to get your attention and have been quite successful as heated discussion in threads here and on other sites attest. I will say that I understand the ill feelings some have as Erik can come across as abrasive. However, his methods do work well and are designed to help shooters not get caught up in complexities when trying to sort out a load. His statement that he does not chase the lands is absolutely correct. He adjust seating depth to keep the rifle in tune and does not give a rat's arse about where the lands actually are in relation to the ogive. The initial relationship after the first handful of rounds can be markedly different after 300-1000 rds but I find that my change in seating depth required to hold the same tune does not correlate 1:1 with my 'new' measurements to the lands. I frequently turned a great shooting rifle into an unpredictable one by finding my best seating distance off the lands and keeping that distance the same as the throat eroded. Since I have started using the CBTO measurement as my baseline and adjusting the bullet out a little over time I have been able to keep rifles in more consistent tune. This is not the same as chasing the lands, as some above have noted, as I am not advancing the bullet based on how far the lands advanced. In some cartridges it has been near 1:1 but never the exact same. In my .284 with 184gr hybrids it is definitely not the same. I may not like the style of Erik's presentations but I feel he is presenting solid and very useful information and an easy way to find a starting point for seating depth not requiring special tooling.
