I'm interested in loading frangible .223 for whacking steel targets at close range.
I have heard that the non jacketed frangible bullets like Sinterfire often come apart in the bore. I have also heard of increased throat erosion using non jacketed frangible bullets. Any experience? The only jacketed frangible bullets I have seen are the Federal. I have some of them in loaded ammunition but have never seen the bullets available as components. |

I have some of them in loaded ammunition but have never seen the bullets available as components. I load 9mm to 50bmg in Frangible for a few of my commercial customers. Sinterfire bullets I have loaded have never come apart in the bore as fas as I know. I have never seen it happen. They are tougher than I thought they would be. 223 rem in Frangible will penetrate 3/16" mild steel plates at 15 yards and closer. The nearly penitrate 3/8" mild steel plates at 15 yards. They work fine on AR500 steel. I have done these tests with my own plates. The plates were face on, 90 degrees to the bore axis. I am not sure about increased throat erosion. I know that Sinterfire bullets have some sort of lubricant in the binding agent that reduces friction in the bore. They actually feel kind of slippery when you handle them. |

There are new restrictions on lead smelters under Bush's EPA - and it will only get worse (much worse) under Obama.
Not only are lead-free bullets likely to be forced on us by the EPA, but also lead-free primers like the police use now for training and also used 100% at SigArms Academy. |

Not that I am a tree hugger. Lead free primers cost more yes, bot not everyone is making them. Lead free bullets cost more sure, but not eveyone is making them. When everyone starts making them cost will come down. Not to mention sintered bullets in theory leave not ballistic fingerprint. Antis won't like that. I am surprised they have not caught on already. Beside lead is bad for you. Unless you like 3 eyed children. |

OK, I might agree with you, for the most part, on the first issue...IE: more producers = Better prices.

Beside lead is bad for you. Unless you like 3 eyed children. But, the whole "Lead Bullets Are Bad...Mmmmm-Kay!" stuff is just bad science. Lead very quickly forms an oxide layer (Lead Oxide) and, if you understand chemistry, Lead Oxide is fairly stable and non-reactive. The whole "We have to get rid of the Lead Bullets!" thing might apply in an extremely poorly vented indoor range, but outdoors, in berms, or where there is adequate ventilation...it is a non-issue. Lead based primers is a whole nother issue. Tall Shadow

Yes lead is bad, bad, bad and must be and cleansed from the earth and banned from the periodic table
But the ban people are not constrained by science, they operate on their enlightened opinion and they know more than you do… And the last thing we need are uninformed reloaders and gun owners agreeing with the bans… |

Both very healthy & smart...sometimes too dang smart! I think you misunderstood me a little. While not versed like you in the science of lead. I was really talking about indoor poorly wentilated ranges. You and I know there are lots of them. I am not looking to get rid of lead bulltes at all. If that is the way you read my post I am sorry but it was not meant that way. I was stating more so that lead as we all know (unless you can prove otherwise) is know to cause reproductive problems and birth defects, and other serious health issues. Eliminating the risk is not entirely a bad thing. Quoted:

Oh they have, serial numbered ammo bills, and bullet marking bills are already in several states Yes they have serial numbered bills etc.... The principle behind the frangible bullet is that they turn to dust upon impact with a target. Poof no serial number and no ballistic fingerprint. Also as a manufacturer, when I sell at a gun show I do not log names of who I sell to. I am not required by law to do so. So I make them then sell them. From there there is no record. This makes point #2 moot. Go here ––––> Barnes franible varmint grenade bullets You will see in the video clips how the bullet turns to dust after impact with fleshy material. |
| I load frangible 42gr bullets in the .223. They aren't Sinterfire, but made in a factory about 10 miles from Sinterfire. With the 42 grain, use 55gr loading data. Pressure climbs quick with these bullets because of the long contact area with the rifling. I use them for blasting ammo and shooting indoors in the winter. They shoot OK out to 1-200 yards. |

Eliminating the risk is not entirely a bad thing. I understand what you were saying..... And I'm not trying to be a hard/smart ass or anything, BUT!!!! The point I'm trying to make , is that the whole "Lead Is as EVIL! as Satan!" type of absolute CRAP that many anti's, and even many Of Us shooters have been spouting...and repeating for far too long now. Lead is a naturally occurring compound. It isn't some super "Man-Made" super poison. It won't spread like has been hyped all over the place (IE:lead leaching everywhere from berms, Etc.) and many of the assumptions that were placed on the effects of lead in our various environments are proving to be false. I use/handle raw, and alloyed lead Every day...bare handed. It's not kriptonite....it isn't going to hurt you unless you eat it, or inhale it's (quickly dissipating) vapors....or inject it in to your bloodstream. We all have to stop "Parroting" the old "Lead is Da Debbil!" Bull S*it that has been being spouted by the media & many unrealistic scientists...doing unrealistic experiments. It is like all of the BS statistics the antis like to quote all of the time. Yes someone said/published them. But THAT doesn't make them correct...it just gives them more ammo to fight Us in the end. Lead, and lead based solders/coatings are being replaced by Tin based ones in most manufacturing sectors. This is VERY!, VERY! bad Ju-Ju! Tin has some MAJOR problems. For example...Tin tends to "Grow" little wiskers...small tendrils that grow long enough to make contact with other near by connections shorting them out. Bad enough when your new piece of stereo equipment or TV blows up....REALLY bad when the Avionics on the airliner you are traveling on fails! Just Think about what you are posting...OK? Nuff said. Tall Shadow ETA: Man I suck on using this new editor! |

Lead free primers = shelf life. No, its not a consiracy. Its a chemical fact. They have not come up with a lead free primer that lasts more than 5 years reliably.
Anyone else notice they just banned lead wheel weights? and I used to work at an indoor range. Never tested over 13, and now I am way below a 10. Lead is not a problem if you handle it properly. |
