Modifying the Factory Bullet

Just wondering if I am wasting my time?

So what I did was take a .25cal 120gr Sierra GK with an oal of 1.155 and trimed it to .99 then added an aluminum tip to get an oal of 1.315 and weight of 118gr.

Why would I do this well because there are not many options when it comes to long range .25cal bullets.

The Sierra 120gr GK and the Sierra 118gr LRGK


From left to right Berger 115gr VLD/Sierra 118gr LRGK/Sierra 120gr GK


Hoping to get some feedback from the guys that make bullets.

    I like it a lot.

    Since ZHAT makes a bullet like this I am not sure others are doing it. Not sure if there is a patent or patent pending status on this concept though.

    But I still like it a lot,nice job!

    Very nice! how did you make the aluminum tip? And how did you attach it to the rest of the bullet?

    Very tallented. Im sure Royinidaho will be jumping in here soon. I think he had wildcat bullets manufacture some of his IWK's that he was making by hand. My guess is tighter tollerances. I think he used brass tips tho.
    Anyway you put it that takes a level of skill and crafstmanship that very few have. Congrats. let us know how they shoot.

    Thank you guys it brought a smile to my face the first time I put them together.

    I made the tip on the cnc lathe that I run at work ( its a mazak 350m quite big for this kinda job).

    The tip is a slight press and I am thinking about using some retaining locktite though I dont know how that will work with the led.

    Man that is a mean looking bullet! I have some early Hornady 162 a-max with an aluminium tip that look very similar, unfortunately I only have 34 left.
    Have you shot them yet?
    Flick some pictures through to Royinidaho, as winmag said he has made some similar ones.

    JLK makes a 108 grain 25 caliber with a .500 BC

    Dave Tooley at Tooley Custom Rifles has been making aluminum and plastic tips for his bullets for years. He would be a very good source of information on the pros and cons of this and give you some good tips.
