I've heard that cutting off the tip, or making cuts to the jacket, can make the core shoot out but leave the jacket in the barrel. This is because of the way the FMJ is made. The jacket is open on the back end, rather than solid like on a hollow point. I'm sure other who know more will step up.
I have done it, and it works, sort of.
I cut the tip off with a sidecutter, then filed it nice and flat. At close range the bullet blows up. beyond 100 it acts like a FMJ.
And I check the bore after each shot to make sure the jacket did not get left behind.
It would be much better to buy a box of soft point bullets and then pull the FMJs and stick in the soft point.
If you don't reload, anyone who does could do this for you.

There was a Canadian company that did this with WWI surplus in the interwar period, they found out about the lead flowing out and leaving the jacket in the bore as an obstruction which would problems if you fired again.
The reason I asked that question was I purchased 1000 rds of .223 FMJBT and was told here on CGN that the round just goes right threw yotes and doesn't do a lot of damage unless you hit major organs. Thanks Guys for the info more food for thought.
FMJBT if I'm not mistaken stands for full metal jacketed boat tail bullet. and whoever told you it would go right through is right. I used to hunt with a 223 and shot several groundhogs with FMJ bullets and unless I hit them in the head they did a lot of dancing till I finished them off . and I didn't like that. as someone else said get yourself some soft points and they will work . if you have to shoot the Yotes with FMJ bullets make sure it's a brain shot.
This can cause significant increases in pressure, the profile is not the same front to back, you have to build up a load if you are doing something like this to be safe.
This was done in the past and there was an attempt to cut FMJ 303 Brit and turn them into SP but it was not allowed to move forward for sale.
This is a potentially dangerous practice, you can have the lead flow out and stick a jacket in the barrel making a bore obstruction.
With how cheap 223 is why not get SP and sight in for that for hunting then plink with the FMJ.

this may be the ONLY example of Cinéma vérité in firearms testing!! Well done!!
(one of the best tests I have seen ... she 'blowed up' real good)
BTW, I am not saying I do a lot of loading, testing and shooting, but the fibre drum you see in the movie is what my powder comes in. 40 to 60 pounds per drum.
RiMP9,
DON'T DO IT!
If you go into Ellwood Epps, look for a barrel on display that has the muzzle peeled out like a banana. This was on display several years ago so don't know if it is still there. My understanding is that the fellow shot a WWII surplus .303 bullet through the barrel but he had trimmed the end from the FMJ. As others have said, the jacket stayed in the barrel and the lead exited. Result, the next shot cost the shooter his life.
