There are statistics behind the sample sizes and variability, it's well established. I haven't seen a significant data set that proves an outlier. Feel free to post your anecdotal evidence in my 18 page thread about the topic.Valid proof is found by the individual reloading for themselves. No one could possibly prove it to another person like you cuz you’ll just say anecdotal evidence is not proof.
I adjust seating depth for every rifle but some rifle barrels respond more than others.
Want proof for yourself? Buy an old K98 and load 175 grain bullets and see how well it shoots and then start seating the bullet farther out and watch the groups tighten up.
The cleaning rod OAL gauge is a cheap and effective tool for finding the distance from the bolt face to the lands, using a comparator. It's great for tracking throat erosion, or adjusting seating depth, if you so choose to do so.
