Legality of home made hollowpoints?

Uhm we've been pressing a philips bit into .22lr for years

I once had a "friend" who did this. Accuracy was not too good, performance (expansion) was terrible. This was on a handful of popular calibers.

...Bullet makers spend a lot of money to develop their hollow point bullets so it will perform.

Yep, as the British found out back when they were trying to suppress colonial uprisings. Expansion is easily achieved as long as the bullet is traveling faster than 2,000 fps.

At less than 1,000 fps, even the best hollow points tend to expand only half the time. That's one of the reasons we practice the double tap. Of course, you could always handload a .357M or 9mmLugar to over 1,800 fps with the lightest hollow point bullet available, if your pistol can handle the pressure and has a 6" barrrel. I've done this myself in the past for fun. Don't waste your time with plated bullets. The jacket separates at about 1,100 fps.

Jacket separation isn’t necessarily a bad thing when hitting soft targets at typically short engagement distances. Energy is transferred and a nasty wound channel could result in a favorable outcome for the defender.

Jacket separation in the barrel is a possibility.
Your friend will be taking the covering jacket and turning it into a tube. Remember the back of FMJ is exposed lead, remove the tip and now the jacket MIGHT separate from the lead core. If the jacket stays in the barrel bad things can happen.

Sometimes a thread is so ridiculous you have to wonder about things.

What?

You mean you don't believe that drilling a bullet will transmit heat through the bullet AND the powder AND the case and somehow still be hot enough to set off a primer?

So use a tmj

Don't be so cheap,buy real hollow points !

Amen! This what I was thinking from the git-go. If you can't afford proper self defense ammo, then you shouldn't be carrying a gun.
