silly question. Bullet setback

[SMSgt]

Am I correct in my assumption that as long as your reloaded ammo is ~.015 inches less than the overlength measure, that you should never encounter bullet setback? I just stumbled upon this revelation when I thought about it a sec. Just wanted to make sure I was correct. If I am correct, than in theory, reloaded ammo should never have set back since the projectiles never engage the rifling prematurely due to the ~.015 margin for jump gap prior to engaging rifling.

Bullet setback is more commonly caused by rechambering the same round over and over. It can and will happen with reloads or fractory-fresh ammo.

Simple solution is--Don't!

As the learned SMSgt said, repeatedly bumping that feed ramp is like whacking it with a hammer.  Sig .357 gained a reputation for set-back,  and straight-wall will do it eventually.

Rotate cartridges when unloading and reloading is done often.  Only load the 'same' cartridges a given number of times.  Shoot the ones that have been loaded several times at the range/in practice.

I have difficult grasping the need to constantly load/unload a firearm. It's no more difficult to secure a loaded firearm than it is an unloaded firearm.

How did a conversation about CZ pistols get mis-directed to Winchester 94 lever actions ?

How do you secure a loaded, lever action 30-30 without a safety, when you are dead tired, tromping back from a hunt, in thick brush/swamps etc? I eject my ammo, to be used for another day.
If you do this multiple times, with the same ammo in a Winchester 94, you get bullet setback.

I left my hunting rifle loaded until the hunting trip was over and the law required it to be unloaded in the vehicle.
