Plus, if they search your house, which they might, especially if you've been charged, they will find your reloading set up and probably things like broken boxes of the same type of bullet in the rounds remaining in the gun and the extra ammunition you caried on your person. If they decide to analyze the powder in the remaining rounds from your gun, they will probably find that it matches a type of canister powder found among your reloading supplies. I think that they'll figure out you loaded the ammunition.
Ok so they proved that you reloaded your ammo. Show me a court case where this A) was ever brought up, and B) it had a bearing on the case. I still don't understand why so many people have this fear, it is completely irrational. I fail to see why the money and time would be spent trying to figure out if its dreaded handloaded ammo rather then just factory stuff. Not to mention what about black powder rifles/guns? Since you loaded the gun powder and the ball/bullet, it would be the same thing as handloaded ammo. Yet I don't hear anyone saying don't do it.
Who decides if you were justified? And if you're on trial, there's some dispute about whether you were justified, and now it's not a "good shoot" until the charges are dismissed or you're acquitted. At trial, things like the type of gun, may, with the urging of the prosecutor, affect the thinking of the jury and may dispose them in your favor or against you.
any lawyer worth his salt could overcome any prosecuting attorney's weak attempts at making you seem guilty because of the gun and ammo your using. I mean honestly what is all of this fear based off of? I have never read a court case where handloaded ammo caused a conviction, nor the choice in firearm. If your justified in using a .22lr your justified in using a 44mag. We can play games all day about what justified means, and we aren't going to get anywhere. Thats why unless someone can find court cases to back up that you wouldn't be justfied in a self defense shoot because of your choice in firearm, ammo type, if you reload, etc it is just a myth.
