Barnes TSX in .223 range report

[JonnyC]

The advice given here is priceless. Quick was right on when he suggested I speed up the Barnes bullet. I'm at maxium powder and velocity and went from 4 inch 100 yd groups down to 1 inch groups. I'm shooting the 53 gr TSX in a bull barrel.

Good to here your down to 1" but you may be reaching some if that's with the 1-9bbl 53gr is getting pretty light. Whats the velosity at?Kurt

It's the slower twist barrel. Velocity is about 3200 according to the book. Don't have a chrono to be sure.

The TSX is an all copper bullet, no lead. Copper is lighter that lead, so the bullet will be longer than a 53 grain lead core bullet. The longer the bullet the faster the twist has to be to stabilize it. I really has nothing to do with weight, just how long it is.  In other words a TSX bullet is longer than a convention lead core bullet, thus it takes a faster twist to stabilize it; even if they are the same weight. You can get by with a slower twist if you push it down the pipe quicker. A 1 - 12" twist will probably just stabilize the longer bullet if you push it as fast as you can, that is why JonnyC was advised to make it step out at near max velocities; good advice I may add.

JIO - Jonny; Barnes says to seat the TSX bullets .050" off the lands, I would go no closer.

Good Luck and Good Shooting
