  4. Smith and Wesson M19-3 .357 Magnum.

Quantity tested 500.

These bullets performed admirably in all respects. Feeding was flawless in both the 1911s. Accuracy was very good and no leading was encountered with any of the firearms tested.

The first load tested was 4gr Unique. Shot Ok but did not cycle the slide in the Kimber Target Model.

Changed to 4.2 gr. Accurate No.2. This load worked so good I am still using it. It has become my current favorite 9mm load. Accuracy is good 1.5 to 2 inches at 15 yards and 2.5 to three inches at 25 yards with the factory sights.

There is no leading.

In the .38 Special with 4.2 grains of Bullseye, accuracy was good at 25 yards producing nice round 2.5 inch groups in the Model 19 ( six inch barrel ) This load did produce minimal leading. Minimal means you could see it but it would not interfere with accuracy for at least 200 rounds.

In the .357 Magnum, 5 grains Unique produced one inch groups at 25 yards from the Thompson Contender with 8x Weaver. and  1.5 to  2 inch groupings at 15 yards from the S&W Model 19. Zero leading
