When CA forced us to use lead-free bullets in the Condor Zone, that edict covered some prime pig hunting territory and forced me into developing pig loads with Barnes bullets.
(Not to start a rant about the left wing lunatics that run the place, but they expanded the law state wide and after many years of data, the condor's lead level has never come down. Don't let them spread this BS into other states.)
I tried the TSX and TTSX, settled on the TTSX. If you are unfamiliar with copper alloy bullets, they are longer for the same grain weight due to their density being lower without the lead.
One would assume they are an opportunity to seat out longer than a conventional bullet, but...
I was completely surprised when those needed to jump. They hated to be near the lands.
I have had to load them now for several friends and every one of those rigs demands large jump to group.
I can't explain it, so I won't try. I just let the gun and target tell me where they want to seat and roll with it.
The good news is pigs here are not hard to hunt and you can easily close the distance so shots tend to be less than 200 yards.
Once you explore the longer jump range, those bullets are very capable of good accuracy and good terminal performance when they hit at the right speeds.
