Grinding a flat bottom bullet
Anyone ever tried grinding a flat bottom bullet (fmj) to make a chamfer to easier fit the case ?
Been searching internet for any feedback on this. Reference 223 THANKS..

NO. The heel of a bullet is THE most important part for accuracy so don't mess with it. If you want to ease the bullet's entry, first chamfer the case mouths and then flare them as you would for cast bullets.

No, but I've chamfered many a case to make flat bottom bullets easier to start.
I recommend leaving the bullet alone. The base is one of the the most important parts of the bullet when it comes to accuracy. on edit: I need to learn to type faster...

If someone had built a few bullets (223) after doing some grinding on the bottom would they be dangerous to shoot out or should they be taken apart?

ive been grinding metal long enough now to know a persons hands cannot and will not grind evenly on all sides of a round object. Try it and i believe your bullets will be out of balance and not fly straight in the very least.

I wouldn't shoot the JHP's if the jackets were ground through at the base for reasons mentioned by Ifishsum. The picture in the link shows a soft point so I don't know if it's the bullet you have. I wouldn't shoot any jacketed bullet that has the jacket open at both ends unless it's a partition type bullet.
Those bullets each look to have enough radius at the base to seat without modification. For the easiest seating look into using the boat tail HP bullets.

Thanks to all for your time and responses.
I am going to pull these bullets to be safe and know better than to do this in the future.
