Thread: OAL - gauge and comparator

Hi team,
I’ve been reasonably successful reloading just using oal with digital callipers but have just got myself a Hornady oal gauge and comparator.

Problem is the old oal and new oal are quite wide spread ( yes I know the comparator makes a huge difference in oal ) but I put my old load and new load into the comparator and they are quite different. I’ll measure when I’m home later and give oal in the comments.

Question is should I go with the new oal from the gauge or stick with my old oal. The reason I ask is I’ve been missing a few animals lately which makes me wonder if my ammo isn’t made properly. When looking at the difference in oal I’m starting to wonder if maybe it’s too far into the lands? Which is weird as I’ve practically been key holing at 100m so not sure what the heck’s going on this why the gauge experiment. Any help is much appreciate.
