Anyone make FMJBT's into HPBT's?

I know that Dusty, but a drill bit just makes the hollow point so ragged and off center that. Wait why am i trying to explain nonsense. Go ahead use a Forstner bit for all I care
 
Darnn the torpedoes and go ahead with your plan.
What you propose is counter-intuitive and seems dumb. However, I have seen worse ideas proven outstanding in their application. Made one of my favorite statements, "don't tell me it can't be done."
I'm in the naysayers camp, that it will significant worsen accuracy, and would *love* to be proven wrong.
Please post your "test" results.
 
:D I would if I didn't mind walking in mud and shooting in the rain!
You won’t have to walk far for what should be your first test. A good stiff backer at 10-20 yards will show if the bullet is coming apart in the barrel as many speculate.

In the days before specialty sub sonic rifle bullets, many bullets were shot backwards and held up just fine. I can’t remember specifically shooting an open base FMJ, but wouldn’t rule it out.

Many loads were high pressure/low velocity as they made the quietest loads.
I have spent many hours doing what everyone else said could not be done. It’s often the initial pressure and acceleration that causes bullet failure in the barrel. You can control that with powder choice.

You can always start low around 14-1500 fps and work up to bullet failure. Plenty of pure lead bullets go down range without liquefying.

Lots to be learned if you think it through.

YEP! So many folks just parrot the "gospel" of something and take it for it's word. I on the other hand, while not from Missouri, I say show me!!
I have my doubts that this experiment will show an improvement but ya never know.

Hmm...wish you had posted earlier. I made rounds with the typical powder and charge I use.
I'll be shooting these one at a time and checking the barrel after each shot. I have a borescope I will be using.
 
I dont think the bullet will come apart in the barrel. Lead cores liquify inside jackets going down range (according to rpm and if the jacket is bonded or the lead oxidized, etc) so im saying it will liquify and just run out the back as its going down range. May take 50yds or it may happen at 200 who knows. A fmj has the thick copper in the front and is balanced that way, while a HP bullet has the copper in the base. Some point their bullets and close up this hole some. Its not really changing the balance just the aerodynamics and the shape of the pressure wave.

Why would the core temp change enough to liquify by opening the tip?

Same bullet, same spin rate, same velocity. Bonded or not, liquid lead would drain or be pulled out the back due to low pressure or vacuum.
 
alrighty..one last time and then i am done.
IT IS NOT THE HP THAT MAKES A HP BULLET BETTER THAN A FMJ.
1) there is a difference in mfg process, the fmj is made from the nose/point down to the base, the modern hp is made just opposite, made from the base up to the point.
2) it is the QUALITY OF THE PARTS and the PROCESS that makes one bullet better than another.
3) there significantly different "hollow points" . some are very small and simply the results of the final step in making the "point", others have deliberate large open tips to promote expansion.
so to be clear adding a manufacturing flaw will not improve the accuracy of a bullet.
