I am building a 20 Tac and wonder what type dies you all are using. I want to use once fired 223 brass as I can't see $56/100 for the Lapua. If I must use new 223 what brand do you like. What steps are you using to neck it down. is it one pas through a case sizing die or do I need to go the sizing die route with the changable sizers? Thanks, Greg |

I'm also waiting for my 20 Tac upper to come in.... I talked to Mike at D-tech, and he said to full-length size with 223 die, with neck expander removed. That allows the neck to shrink, but not re-expand upon removal. Then, use full-length 20 Tac die to size down to proper dimensions... Be really carefull how much lube you use, as you can dimple some brass pretty easily.. I should add, I have the 20 tac 2 piece set from Redding ( the only one's I've found) Hope that helps, Telephoneman |

The barrel is 25" long Pac-Nor Stainless 3 groove, .935 diameter, straight cylinder, no taper. I use Reloader 10X if I'm just loading a few on a standard press, but it doesn't work well in the Dillon powder measure. For large quantities of ammo, I switch to AA2520. Primers are CCI#41. Five shot groups average 3/8" at 100 yards. With IMI SS109 cases, I can get the 33gr Hornady bullet to 4300fps. Tony |
