Bullets With Grooves

[adam32+P]

I wonder how the Lazerhead bullet would stack up...it's undersized and then built back up to spec with an electrolysis coating (I think), it is pretty groovy too.

The best part of the a tip is that hornady itself used to have an aluminum tip if I read what I read correctly. A new revolution again, just like the last one!

Oh right!!! The 50 cal 750 grain amax always had an aluminum tip to begin with. Thanks for jogging my memory ahha

Not to argue but from what I've seen the H-Mantel doesn't have two sections, but rather a crimp in the middle. The Partition has a complete separation between the front and rear sections. The rear acting as a FMJ with a wide meplat. So

It's also possible for two different people to stumble upon the same big idea…Newton and Liebnitz each independently invented calculus mathematics with no knowledge of
Each others work for crying out loud. A bullet with a divider inside it is nothing compared to that. Certainly wouldn't say Nosler copied it.

I have not desected a H-Mantle but looking at their website's cross section the construction is different. Maybe completely different. The H-Mantle lead is one piece with a crimp in the middle. Maybe a heavy crimp but still one lead section. The Partition's jacket in made on a screw machine drilling out the front and rear sections from a solid plug. Then two seperate lead slugs are place into each section and pressed in a series to final form. So though they are similar they are constructed completely differently. And thus have a different terminal performance.

The Partition jackets are made on CNC screw machines? Do you know the cycle time to do this? Based on the volume of Partitions produced there must be a place to shorten our cycle time.

Last I saw they were made on the old screw machines that I think Big John A got. That was over a decade ago. I don't know if that's what they still use or the cycle times..

From what I've seen on running swiss machines don't see where you could improve the cycle times based off your video. I'm sure it's possible for a talented programmer but my best guess is you'd run into some kind of issue with reliability or consistency at one point. As you know less steps taken then decreases cycle time. The more machines running the more output is. But then you'll need more operators or farm out some of the work.

It all started with one moose. Hit right, it didn’t go down—which sent John A. Nosler on a journey to make a better bullet. We know it today as the Nosler Partition.

Found this article. Pretty cool. Makes sense now.

Her is another article. CNC Swiss screw machines were invented in the 60's and became available in the 70's. This means Nosler was turning jackets on a manual lathe.

I thought I liked doing things the hard way. Wow. And people to this DAY complain about the price.

I got to meet and speak with Big John A on several occasions. And though I wouldn't say we were buddies he made quite the impression on me. He was a true gentleman much like I imagine our Jerry was. Very generous with his time and made people feel very welcomed. So if I embarrassed or caused anyone any ill feelings I apologize. I just wanted to speak my mind on someone who felt he made the world's finest bullet.

Not much love for the Partition around here. I believe it to be the most innovative bullet of our time.

I perceive it differently. And the hunting world doesn't revolve around long range hunting or shooting. Most shooting or hunting is 100 to 200 yards. 400 yards is pushing pretty hard for the average shooter. So standard or premium lead bullets would cover the majority of shooters. Match level hunting/ target bullets covers most of the long range hunters/ shooters. Which is a pretty esoteric arena. Most of the elk hunters I know use a Parition and limit their shot to 300 yards. And they're pretty successful at it.

I mean it's still the yardstick against which all other premiums are measured as far as I'm concerned…but I also don't use them haha

I'm a huge fan of the federal trophy bonded tip and the trophy bonded bear claw before it. Good design.

As far as monos go I had a thought the other day about a manufacturer called "cavityback bullets"…

ITS JUST A LEAD FREE NOSLER PARTITION!!!
