mini chop saw with a jig he made up to trim cases. collet inside a fixture with an endmill in a drill press to trim. and a recovered bullet |

When it comes to the cost of a die thre are a few variables. Diameter, type of die, etc. For me exchange rate is a cost as well. I have never reduced a finished projectile in diameter but you may come into trouble with brass spring back while the lead core does not. D Corbin is the man to ask. Just google him and his company. Thre are a few others who may chime in on this topic. Ref how heavy can you make them..my projectiles are straight walled and the longer I make them the more friction in the PF die, so there is a limit. There are 50gn projectiles out there. You will find that they have a few tapers on them, boat tail, rebated, long points etc. All this helps reducing friction in the PF die as well as improving flight quality. The amount of bearing surface on those long projectiles is quite small. To S Slayer Thanks for putting the pics in. You are spot on, that is a 20gn Vmax. As you can see there is a bit of work involved. The draw trim die can save a lot of work though. The cut off saw and collet / drill press method also works when making short jackets for my 40gn round nose in .224" Bill |

50 grains?
50 grains is way over the heavy end of what I was looking for. I was looking for something around 37 to 40 grains that runs about .663". I have some NOE cast bullets that are .559" long when cast with Linotype they are supposed to be 32gr, when cast with pure lead they end up around 33.4gr.
So I was thinking that the 40gr .181" or 4.6mm bullets could be sized down to .172" somehow if I was careful. Last edited by 17tbs; 12-10-2017 at 06:29 AM. |

Casting a 17 cal
OK you are using cast. Different bucket of fish. Have fun.
Would like to hear how they go. Bill Last edited by Bills Shed; 12-11-2017 at 08:10 AM. |
