i realize what you are saying, i did the push test earlier, with the extreme 124gr FP bullet, i came up with 1.142, loaded a few dummies at 1.125 and they go in fine and for some reason the 1.100 do too now, wonder if the 15 deg weather had something to with that, but here in the 70 deg basement they work slick, you can see on the feed ramp where the plating contacts on the ramp.
if push test came up with an OAL OF 1.142 then why did you load up at 1.100? 1.125 is what you should be trying.
