Thread: Who still makes 0.223" diameter projectiles?

I had an older ZKW465 with the .223" bore. I used to used .220 Bee projectiles, .224 caliber and provided you start low and work up following the usual best practice for handloading you should not experience anything adverse. After all, you are talking the difference of nominally 0.001", this is less than the diameter accuracy error of the projectiles in some brands of ammo. Also, when you are jamming them down the bore the engraving of the rifling into the projectile is more than the difference you are talking here. Also, if the rifle you have has had a fair bit of use it's probably only .223 at the muzzle end anyway!

More of a factor for me, is that the .223 bores in these older rifles were usually sourced from rimfire stocks - likely to be softer steels and slower twists (usual for rimfire being 1-16" if I recall correctly).
