This is definitely not an apples to apples comparison and ONLY my thoughts after 125 rounds of each load, shooting on 2 different FITASC Parcours alone with no one yipping in my ear and no outside distractions. Targets were 20 yards to 50 yards in distance, everything from a short lazy looping target to full on crossers that were curling and many variations in between.
The two loads were:
Federal Top Gun hull
Federal 209A
18.5 Grains 700-X
CB6100-12 wad
1 oz. West Coast Magnum #7.5
1,250 FPS (not sure about the pressure because I subbed the wad and the hull but the velocity was actually measured. It is derived from a Federal Gold Medal load)
Cheddite 16 gauge
Winchester 209
18.0 Grains American Select
DR-16 wad,
3/4 oz. West Coast Magnum #7.5
1339 FPS 9,480 PSI (Tom Armbrust tested the load)
Don't get your panties in a twist read what I have to say, before making judgments based on gauge and velocity.
I did my normal practice routine, choose a peg on the parcours, shoot each target as a single twice, then pick a simo pair (voice release can only do simos) and shoot the pair 4 times in a row. I did that multiple times on one peg per parcours, shot as many different pairs as I could. I shot all 125 rounds in the 16 ga. first and then shot the 12 ga. because the guns are completely different. The 12 gauge had a U3 Muller (0.020") The 16 gauge had a U2 (0.012") and a U3 (0.023").
I could not tell that I was using a 3/4 oz. load to break the targets. There wasn't any target I couldn't break with the 3/4 oz. load. Targets that I had trouble breaking with the 3/4 oz. load, I had trouble breaking using the 1 oz. load.
The one difference that I did notice was with the 16, which I normally use either 7/8 or 1 oz loads for clay targets......The U2 was not enough choke for my liking with the 3/4 oz. loads. Until today I had never seen a difference in the hits between the two chokes until you were shooting the 50 yard stuff. Today I could see the difference at shorter distances. The U3 chokes in both gauges gave similar results even with the 50 yard targets.
I developed the 3/4 oz. load several years ago so I wouldn't beat up the wood some of my older shotguns with excessive recoil and I normally load them down to 1,250 FPS. Today I didn't load them down.
I will not give up my 1 oz. loads any time soon. Probably not until there is a rule change. I do think that there is the potential to give up a few targets using the 3/4 oz. load and I am not willing to find out the hard way in competition. Since you normally get punches by only 1 or 2 targets, it isn't time to gamble. Now in the fall when I put my 12 gauge away and shoot the 16 for sporting clays, I might try the 3/4 oz. load out then and see what happens. Might just try it for side events too.
