You know, that thing "won't fit"... sometimes it is the shoulder, from one chamber to the next the actual shoulder length can differ. I had that issue in going from one rifle brand to another, bolt would not close on the round. solved it by re-sizing the brass down a couple more thou's.
Course you'd have to break down those loads all the way but you might check that.

Hope that was a typo... it might only take 2 thou (.002), do you have a case length gauge... measure a successfully fired case for shoulder datum then down 2-4 thou is your typical resizing setting. I do 4-5 b/c I have more than one and wanted 1 setting for all. I had one with a really long chamber but got rid of it, too much case stretch for my taste.

Ok, that makes sense...
I looked up my howa data, I didn't shoot a lot of the gold dots (BC 0.457) but do have 1 line item in my data for them, I used 2.280" for an OAL.
I haven't loaded them since then (~ 2yrs ago) b/c they are OOS and I don't have a lot of them on hand.

I dont have my load books handy.

But with the howa I had and my 3 cz grendels. The 120 gold dot nearly falls out the modified case before it hits the lands.

If your throat and mag allows the 120 gold dot to run a length of 2.330 ish max. Varget is the money maker powder. I'm talking ridiculously low sd/es numbers and speeds faster then cfe223 and leverevolution can make.
