Are these still coming along? I keep forgetting to call up there during business hours.

Hearing Frank and Mike talk about the terminal effects the nose ring could give you with a smk or similar caught my attention. I'm sitting on a buttload of 175 smk's and if I could make them more effective for pigs it would be awesome.

    Bumping up an older thread. Any more word on these?
    I don’t see them on his website but he is selling the DTACs with the nose ring already cut.

    I can tell you that it’s a manufacturing issue holding up release of the tool. After talking to the designer of the tool last week about the nose ring cutter it’s getting the manufacturer to produce the tool body to the required specs that’s the problem.

    D. Tubb is not difficult to get ahold of. He does not play word games. Call SSS and ask him. You will get the straight story from the source.

    Does Warner Tool use this Tool to put the nose ring in their Solids or do they use some other method?

    Noob question, but what is a nose ring?

    Somebody had to do it. :p

    Seriously, it's a tool for cutting a ring into the jacket of a target bullet just below the tip in order to make it expand/fragment more readily when used to hunt game.

    Actually I'm pretty sure the original purpose was to make the bc more uniform from bullet to bullet. Enhanced terminal performance was a unexpected side benefit.

    It has been a while since I listened to this episode, but I think he talked about it in there somewhere? Great podcast either way.

    Cool. I'll check that out.

    edit: Good info in that podcast about how Tubb determined the benefit of the nose ring and a Lapua-style rebated boat tail. I went to his website and found this description of his 6mm 115gr DTAC -

    The creation of the Nosering application was a direct result from hunting experiences of which many excellent impacts “Ran Off” as the result of a nonexpanding DTAC bullet which has virtually no catalyst (other than hitting a bone) to initiate repeatable expansion. This resulted in experimentation using several different approaches with a goal of modifying these very accurate bullets in a way so as to create decisive expansion upon impact.

    There were other benefits from cutting a Nosering on a DTAC bullet. These include increased uniformity of the drag coefficients not only during supersonic flight but also subsonic velocities.

    Our feedback data speaks for itself; Not only does Nosering make your DTAC bullet deliver better shot to shot drag uniformity , which results in your vertical groups becoming smaller, but it also allows you to initiate expansive qualities. Takes a great target bullet and makes it a fantastic hunting bullet.

    The DTAC with its Closed Nose (pointed tip) will show better shot to shot drag uniformity which will translate into smaller vertical group(s).

    For a target shooter this means your DTAC group(s) will become flatter since your specific lot # of bullets that can be characterized as brothers and sisters will after a Nosering™ react more like identical twins. A Nosering will result in the bullet BC spreads being cut in half.

    The Nosering tool allows the hard bullet jacket tip to fail due to stress fracturing on impact and which is driven into the lead core of the bullet. This initiates dramatic bullet expansion.

    Actually, talking to David it was the other way around. He was shooting baboons and wanted the 115 DTAC to expand and not just punch a hole in the animal.
