I reload .223 for my carbine and I was wondering about the charge for total copper bullets. I have a load worked up for 55gr FMJ with AA2230. Can I use the same charge with Barnes 55gr copper bullets? Any help with this will be appreciated
THANKS!! |

While you can technically use the same load for both 55gr bullets, you will not see identical performance from both, as the length of the bullet, its uniformity and/or the ballistic coefficient are different.
So your current 55gr load may be a good starting point, but stick with the basic rule and reduce 10% for your initial loading. |

Quoted: No. All copper bullets use different data due to their longer length. Actually, because copper weighs less than lead and a plated bullet has a much higher percentage of it's total weight as lead, plated bullets are slightly shorter than equivalent jacketed bullets. The real reason you load them using lead bullet data vs jacketed data is because the soft lead core and the thin plating causes them to obturate much more tightly to the rifling causing a better gas seal. Therefore, they act more like lead bullets. |

THANKS!! Solid copper bullets have their own load data. The bullet is significantly harder than a lead core jacketed slug so the engraving force in the rifling is higher. You meed to work up a load with them like any other change. |

I just picked up a brand spankin new Glock 19 for way under dealer cost. So to celebrate my savings I bought 2 boxes of Barnes 115 grain 9mm TAC-XP, M\LE bullets. They are as long as 147 grain JHP..... Translated, this means a Barnes 115 grain 9mm bullet seats way deeper than an ordinary 115 grain JHP. Way, Way Deeper.
Included in that order was a Barnes Reloading Manual # 4. You should not use any data for any Barnes bullet that doesn't come from Barnes manual. Just as dryflash3 suggested. |
