The ruger no1 action is over built. Built like a tank. In a Ruger#1 chambered in .223 has anyone shot a good amount of 5.56 thru theirs?
Any issues?

There are two issues.... the leade and the pressure.

With a #1, the pressure should be a non-issue within reasonable limits. The leade is longer in a 5.56 chamber in order to still allow some "jump" when using the 77 grain+ bullets when the ammo is at max OAL.

Take your ammo of concern, pull the bullet, and discharge the primer. reseat the bullet long with no crimp, and chamber it. Extract it and measure the OAL.... you will now know the OAL (with that ammo ONLY) which puts the bullet on the rifling. .005 to .010 jump is usually adequate to keep the pressures where they ought to be.... having the bullet on the rifling can increase pressure substantially.

I'd read the manual....and if that didn't help, I'd ask Ruger.....and if that didn't help, I'd have a competent gunsmith check and/or recut the throat so's I'd know for sure.
