Just received a long awaited 7PRC prefit from a reputable vendor here.
Prefit for a Curtis Axiom LA previously wearing a 300WM tube from MPA
Forster FL bushing die
New Nosler brass.
I DONT have a go gauge yet, they are all on backorder. its on the way.
I DONT have factory ammo in hand yet, but will try that tonight.
After mounting up the new barrel with a quality torque wrench and appropriate high-presure synthetic grease, I've got an issue.
Dropping fresh brass into the raceway, bolt will close with reasonable pressure.
After running same brass through the FL die to uniform them prior to loading, bolt will only close with a hard push. Enough of a push that to roll the rifle over on a bipod. Enough of a push you can't run the bolt. All the resistance comes in the last 1/8" of bolt throw and requires force to close lugs into the stops.
Dykem on neck and shoulder shows no contact.
Bolt face shows significant brass transfer.
Will be mic'ing everything tonight when i get back from work, but google-fu has uncovered numerous threads about Forster dies inadequately sizing for minimum spec chambers.
is it possible that the die doesn't adequately size case head/web area with my (redding) shell holder ?
i'm a competent, but unsophisticated reloader and could use some guidance on troubleshooting.
thanks
