Hollow point

[Stephen Borud]

After seeing Daves little bullet clamp I had to make one. Found a little time yesterday and today to build one. The bullet went from 469 grains to 429 grains. I quickly drilled the hole in the meplate of the bullet so it's a bit off center......had four hungry boys wanting Dads homemade biscuits and gravy, so time was of the essence. I will be interested to see how accurate it is if at all! If it is then I will be curious to see how it performs.

Hey Stephen GOOD JOB !!!!!!!!!

With the Mill you can center up really well and quickly

Stay safe

Oh Stephen !

Before the hole in the nose you could eat a steak right up to the hole. Now you have to eat the hamburger it makes

Thanks Dave!

Kurt, it won't be that bad hahahahahahaha or??

Big hole in, lots of meat damage, bigger hole out, if it makes it all the way through. If you manage to get hamburger, it will be bloodshot.

I found this out using a 340 grain Gould hollow point years ago, and when I hollow pointed a 520 grain Govt bullet, it didn't help too much in the blood shot meat dept. I don't think you're gonna like it. Shoot straight, rdnck.

This is an interesting thread. I was wondering what might be the easiest way for me to hollow point bullets and I found out that the 1/2" ER-25 collet for my lathe will easily hold .45 cal GG bullets but will not quite close up far enough to hold .44's or .45 slicks but there are collets available, if you shop around that will allow the job to be done easily. I havent mounted up the collet chuck yet and tried it but my guess is that it will only have to be tightened up hand tight and I do have a stop that can be put in to maintain the bullet depth in the collet. A centerdrill in the tail stock chuck and a flag and dial indicator will work to maintain the hole depth.
One thing I do wonder about is if the hollow is off center some, how much does it have to be off to effect accuracy? Will it show up at 100 and or how much more will it be pronounced at longer ranges?
Something for you more experienced shooters and those that still have good weather to contemplate and maybe experiment with.

I chucked some of my swaged bullets up in my lathe to see if the collet would damage the bullet. It works fine.
I wanted to swage some lubed bullets.

Rdnck's exactly correct on the damage side, this pic gives you an example of what you can expect----It did reduce the "run after shot range" from 50 to 100 yards to under 50 yards.



This is the "offside" the "onside" was the normal 45/50 caliber hole

I made the fixture to play with at the house---its doesn't even mar the bullet surface----collets were a bit inconsistent for me specially with soft lead.

Sam: just for grins i rolled the bullets on blades to see if i could find any imbalance---when truely centered the bullets shot well out past 200 yards ----it is a bit tricky to get the fixture lined up, when it is its very repeatable with simple stops

Keep safe

Dave, it may depend on the collet that your using. If your using 5C collets they they most likely vary and damage a little due to the way they work and are designed. The ER collets are a little different, but like I said I just popped a 1/2" collet in the chuck to see if it would tighten up on the 45 bullet and it did.
As far as getting your fixture lined up, I would probably use a dial indicator to dial in the spindle to the bullet, but thats just me, being an old tool maker doing things that way had become habit over the years.
Maybe one of these days I will dig though my inventory and see if I have some 400 gr bullets cast up and hollow point a few of then just to see how things work.
But all in all, for every problem you can think up there is often several different ways you can end up at the solution, not all of them will be the right path for everyone,but most will end up at the same place in the end. Just use what works best for you and all is good.

Yup Sam as an old engineer i agree !!!!!!
