Lever Action in .243

Good afternoon!
In a tube-fed rifle, is it possible for the point of one cartridge to strike the primer of the next one with such force to get it to go off?
Or is this urban legend?
Thanks!

Not an urban legend, it really can happen. This was tested and proven back in the 1950s or so by some gun rag writer. Under recoil the rifle moves backwards, but the ammo would travel forward in the magazine tube because of inertia. When the ammo is forced to the rear by the spring and hits the cartridge stop, the force can make the tip of the bullet detonate the round ahead of it if it strikes in the center of the primer. Now, what are the chances it will happen at any time I don't know, but yes, it can happen. But since there are no tube fed-lever actions in .243 made commercially, it's not really a concern.

A gun writer made a test rig and yes it will.
The manufacturers thought so.
Consider the Remington M141 and its spiral fluted magazine tube to misalign spitzers from primers.
Consider the 8mm Lebel Balle D with the groove around the primer to trap the point of the solid bronze spitzer.
Consider the Hornady FTX pointed rubber nose bullets.

further

Note too that all commercial ammo loaded for tube fed rifles (.30-30, ,35 rem., pistol calibers .44, .357, etc,) are all produced with RN or similar blunt tip.

I recall an article addressing the topic as well, say circa 1980?

Note that the lever action rifles made for 243 or similar cartridges such as the Winchester 88, Savage 99, Browning BLR, and the Sako Finnwolf all have box magazines of one sort or another.
