Anyone make FMJBT's into HPBT's?

I wouldn't feel the need to lie but if I had such a "bad trait" I could lie.
And lying is not always a bad trait. Ask the Jews who were in hiding under Christians in WWII when the Nazi's came knocking on the Christians door asking if there were any Jews around. I know, I'm the product of such a case.

I started to answer and then realized it would be a waste of time.
 
I have heard that you actually might "blow"(extrude) the core out of the jacket if you have openings on both ends of the bullets. Might leave a jacket in the bore.
Read about this decades ago because of people cutting the tip off of FMJ rounds and using them to hunt.

The British Army fighting the tribal insurrections on the tribal NWFP (North West Frontier Province) of India in the mid 1890s learned of the potential hazards of this practice. Issued with the then new Lee-Metford rifle in .303 shooting heavy RNFMJ bullets, they too often failed to stop highly determined tribesmen in the charge. There were recorded cases of men hit three to six times still reaching the British lines and running amok with various nasty bladed weapons. (Same issue as US forces in the Philippines with the .30 Krag against Moro tribesmen.)

Many troopers filed the jacket nose off to improve the bullet's terminal effectiveness. However, cores blown out and jackets left in the bore occurred. The temporary answer was the expanding bullet developed and made by the Indian Dum Dum Arsenal, hence the name for expanding bullets in common parlance, followed by a series of three hollow-tip models developed at Woolwich Arsenal in the UK.

Many years ago, I had a 303 MK VII (Spitzer FMJ) bullet jacket fail on me in a Ross rifle. The front-end of the jacket apparently split as the bullet entered the rifling leaving a near perfect copper alloy tube stuck just ahead of the chamber. The core of course went somewhere down range. Luckily, enough jacket stuck out into the chamber to stop another cartridge being chambered. Brig. Gen. Julian Hacker mentions 150gn FMJ bullet jacket failures as common too with early production lots of the original .30-06 round and many M1903s ended up with several inches of thin tube swaged into the rifling and rolled several inches long by the passage of subsequent bullets. Apparently and surprisingly, Hacker reported no great increase in pressure, but doesn't comment on how well such rifles shot after such treatment.

So sure, cut the tips of your FMJBTs, but be aware that there are risks involved.

Best read on the thread so far. Thanks.
 
I had read story's of the Moro tribesmen and a concoction
of a drug they took before going into battle. They did'nt
feel anything when hit unless a heart or head shot. Officers
carried the short 38 S&W that had little penetration. NCO's
that could carry these, pulled and reloaded the bullet backwards.
Winchester model 12 pump shotgun of 1897 was the most
effective but too few were on hand.
 
I've read and heard that HPBT's or variations of such are more accurate than FMJBT's. I have a truck load of .308 FMJBT's and a mini-lathe. See where I'm going with this! Any thoughts?
one factor that makes a HPBT more accurate is the base is part of the jacket which makes the base more uniform and therefore when the bullet exits the muzzle there will be less bullet tipping because the escaping gases will have a more uniform exit.
 
... Lee-Metford rifle in .303 shooting heavy RNFMJ bullets... troopers filed the jacket nose off.. However, cores blown out and jackets left in the bore occurred..

I'd venture Laurie that those early RN jackets were far more susceptible to jacket stripping than the later 174s. Using side cutters roughly would be a good recipe.. :)
 
Alright, since I've been away, I guess I need to finish this thread.
My "experiment" showed no improvement.
They shot pretty much the same as the untouched FMJ's maybe a little worse..
maybe.
I had none of the potential issues that many said could/would happen.
This was just an experiment of curiosity due to something I read/heard or watched years ago.
It was fun to try and see what would happen.
So now ya'll naysayers can cheer and tell me "I told you so." You were/are right.
Thanks to all that didn't çřäp on me for trying this and to those that did, thank you, I should have listened. :)
