Thread: 270wsm rl26 145g eldx my experience

So I've hit a wee snag, I bought once fired factory Norma brass off a mate, I full length sized them then prepped them, primed them and loaded my ladder in them.
I noticed when I was at the range the bolt was very hard to close on them.
I thought maybe just tight cause they are in theory fire formed to someone else's chamber.
So when I went to do some more testing I thought I'd full length size them again and check case dimensions because even though it's only twice fired it's worth eliminating the easy stuff.
I checked with an empty full length sized case and nope still tight as fuck.
Measured the cases and they are well within spec, so I coloured one in with vivid to see if it marked anywhere when chambered, there is a small mark on the shoulder but not as much as I would expect given how tight it is to try and close the bolt.
I'm putting off any further load development until this is sorted.
I also checked the reloads that came with it when I bought it, most of the brass looks pretty well used and I won't be using it but they were a bit hit and miss some chambered easily/some didn't.
I found an older fired case and measured it up and it was below minimum case length and it chambered fine.
I have never tried any factory ammo in this rifle so can't comment on that, suffice to say its going to gunworks tomorrow to check head space.
I will also point out that the chamber was thoroughly cleaned in case there was grit or build up on the lugs and chamber.
Keen to hear any predictions on what caused this ???
It really seems like the chamber is too small.
