Tests using Beretta O/U with jug chokes

Tests using Beretta O/U with jug chokes.  Following tests were shot using 2.5 drams (68 grains) of Goex FFFG.  The shot charge was supposed to be 1 ounce of nines. However, the pellet count would indicate that 1 1/4 ounce of nines were being shot.  Subsequent weighing of the charge confirms that the shot charge was slightly in excess of 1.25 ounces One over the powder wad and one over the shot wad.  No cushion wad was used:

The 51.1 percent pattern density is equivalent to a skeet choke.  The probability of a hit at 20 yards was a follows:

Probability of hit
 0-10" 0-20" 0-30" sum norm
Edge-on 100.00%99.40%91.40%95.00%99.10%

+/- 0.00%0.00%0.10%0.10%0.00%

While this patterning was more than satisfactory, this load does probably not produce adequate velocities.  The estimated velocity for a 2.5 dram/1.25 ounce load is only 840 feet per second.

January 17, 2011 Initial Testing of Candle Cartridges

    The inital testing of the candle cartridges were preformed on January 17, 2011.  Testing was done with the Beretta Over/Under and one ounce of number 4 shot.  All tests preformed at 20 yards

January 29, 2011 Candle Cartridge Testing

posted Feb 25, 2011, 12:11 AM by Peter Lucas   [ updated Feb 25, 2011, 5:11 AM ]

    On January 29, 2011, additional tests were preformed with the “candle cartridges.  The results were generally disappointing.  In order to make construction of the cartridges easier, I put a piece of paper inside the candle mold prior to pouring in the binder.  I also used a mix of 80% Crisco and 20% paraffin as the binder.   The candle cartridges had a one ounce load of 6 shot with an equal volume of FFFG.  The tests were performed with a Beretta Tercentennial at 20, 30 and 40 yards.

Here are the results:

Based on this sample, the loose charges out preformed the candle cartridges.  I am going back to the original method of construction and pure Crisco for some more testing.
