I have been shooting Bullseye pistol and using the great H&G 68 type of 200LSWC. I have also been using Bullseye. My 50 yard load is 4.0 grains Bullseye. This is an old staple of Bullseye shooters and superbly accurate. I am running the stock spring with all my loads.
Recently I went out and tested some lower velocity loads. I wanted less recoil for the timed fire and rapid fire sequences at 25 yards. I suspect the 3.5 grain load, which is what I use, is less accurate than the 4.0 grain load, but the recoil is less. Shoot one handed and try to keep all shots in a two inch circle at 25 yards, in a rapid fire sequence, and you will lust for low recoil. I dribble oil over my 3.5 grain cartridge cases, to break the friction between case and chamber, and ensure reliable extraction. It is messy as all heck as the magazines become oily, and oil is blown out into the air in front of the pistol. But I don't have malfunctions, something I was having around 100 rounds into the bullseye match when I used non lubricated cases. I had a couple of failures to feed with the lighter load with dry cases and dry chambers. Actually, the chambers were pretty foul by the time I get to the 45 ACP stage. I shoot the same pistol through the 90 round centerfire pistol match and the 45 ACP match. After I started dropping oil on my rapid fire and timed fire rounds, I have never had a failure to feed or extract with my light loads.
All my loads are thrown on a Dillion 550B, the charges are an average of ten throws.
