my 110BA experiences this on occasion with Hornady cases... but not the Lapua cases, so far, that is.
Two possible issues... the cases should not be 2.725" inches... trim to 2.715". The Hornady cases that stuck in my chamber were 2.725, and the ones that did not stick came out at 2.715"... so there's something there...
I have also noticed that the Hornady cases will NOT admit a bullet to the case mouth after firing; in other words, you could just put prime them, put powder in, and seat the bullet again... the chamber reamers Savage is using must be super tight.
With the Lapua cases, you can just *barely* fit a bullet into the fired case necks... and even on some of the Lapua cases the necks seem too tight to get the bullet to go in (just like with all the Hornady cases).
So my best guess is that you have some carbon fouling in the case neck area of the chamber, and these case necks are grabbing there. Clean, clean, and clean some more and get that fouling out... then make sure your brass is totally clean (no powder fouling on the cases at all, especially at the necks)... and I think you'll find all will be well. I would probably soak the chamber neck area in some Hoppes 9, which will soften that fouling gently without being too harsh... it'll just take an over-nighter or two... but it'll work.
Lots of folks pay extra for custom chambers that are just like the chambers we see on these 110BA's... so it's a good thing, really, once you get to know the idiosyncrasies of them. This will help the brass last much longer than it otherwise might...
