hollow point drilling??!??

Hi and welcome to the forum. This is an older thread but still has a lot of relevance to some who are just starting out.

As previously mentioned, while not doing it as a business I have been doing the loading for a while. In this time I have learned plenty of things that work and that don't. Years ago I tried the "drilled" version of a HP and while I can say I got some expansion I cannot say it was controlled by anything. That said I wasn't quite as prepared for it at the time as I was when I started pouring them for specific uses.

The fellow who started this now had several videos posted and has things going good now.

Hope to see more from you especially in casting.

Yes, you can drill a hollow point into the nose of a bullet and it MAY result in it expanding a little more than if you had not drilled the hole (the hole providing space for material to move into as the bullet "mushrooms") but it is unlikely to be as effective as purpose-made hollow pointed bullets.

ALSO, care should be taken using such tools. Using one to turn a soft point jacketed bullet into a jacketed hollow point is likely to be safe enough and not impact accuracy (assuming the hole truly is drilled dead center).

BUT bullets that do not have a solid base, such as FMJ bullets, should not be drilled as there is a risk of shooting the lead core out of the jacket leaving the jacket behind in the barrel where the next shot could result in catastrophic failure from an obstructed barrel.
 
Back in the 60's being a 10 year old farm kid we got the idea of drilling round nose 22 bullets. Not sure how grand they worked but to a couple of 10 year olds they sure seemed to to the job on gophers.

Can't agree more.

Back when I was a teenager in the '70's, my dad and uncle set up a jig to drill out SWC and WC to see if they could get better expansion. They went back to a standard SWC as it seemed to be a bit more accurate and a .45 would stretch out to .68
 
As noted above, this has been going on for a long time.

Nothing new about it.

And no issue with having a good time playing with it.

It takes some very good engineers and testing setup to get a good reliable HP that works.

It took a long time and a lot of research money to get SD ammo to work across the range of guns.
