I had planned to do most of the testing @ the 25 yard range, so I set up there first. Two main goals, testing PC boolits in 4 guns, 2 pistols, a revolver and one lever gun rifle. The GP-100 and the Rossi are both .357 magnums. The goal is to have one load that not only functions, but is also accurate. That goal was realized, but is off topic from this thread. Load for the 357's was the Lyman 168 SWC, 2400 powder, 12.7 , 13.4. Velocity was AV 1468 (12.7), from the Ruger Average 1468 for the 13.4. Rossi was Av 1687 for 12.7 and 1742 for the 13.4. Groups were acceptable for my old eyes and those awful buckhorn sights on the Rossi.
The CZ-75B in 9mm was checking a new lee 120 TC, NOT a TL design. I also have the same boolit in the TL configuration. All coated with HF-red.
The forth is my Bushy AR in .223.The Lyman boolit I tested is the one in the pic I posted. Problem is I simply ran out of daylight. It would have taken another ½ hour to break down, move, and set up at the 100 yard range, our ranges are all separate. So I elected to test the .223 @ 25 yards, mostly to see the velocity, did they lead, and if they stabilized.
Results? Groups @ 25 yds, terrible! That rifle with jaxeted will put one on top of another @ 25y. Velocity was as expected for the powder charges and all boolits hit point first, nice round holes. Groups were round shaped, best was 1".
H-335 23.0 grains, Lyman 224462 coated, then gas checked with Hornady GC's, sized to .224.

Bore was obviously in fired condition looked normally fouled. Clean-up was simple, dry patch showed no lead, patch soaked in eliminator bore solvent, (bore-tech inc.), came out black. One more saturated patch followed by a .223 bronze brush, then a bare patch showed more black carbon fouling, so I repeated the soaked patch followed by a dry patch. Bore sparkles, no lead to be found!
