This was the question I found myself asking yesterday. And in my case the answer appears to be four.
There is my main IPSC competition load, a 200 gn PTC projectile over 5.7 gns Tightgroup, and my practice load, a 230 gn LRN powered by 5.4 gn Win 231. Both run to a Power factor of 176 and shoot to the same point of impact out to 30 meters, but the plated projectiles have a definite edge on the group size area so get chosen for competition.
Next up in the load I use for our 90 round Service Mach (an abbreviated 1500 course) and the 48 round Classic Pistol Match at 10 and 25 yards. PF only needs to be 120 and my IPSC ammo is a bit of a handful during the one handed shooting strings, so I load 3.6 gn Mulwex AP50N under a 230 gn LRN for a 130 PF. Nice, easy to shoot and accurate in my Norinco Ranger 1911 pistol.
And the last load, which is under development, is for Wild Bunch matches where everything is shot one handed but requires a PF of at least 150. The Hodgdon reloading site gives a starting load of 4 gn Tightgroup under a 230 gn LRN for just over 700 fps (161 PF). As i already have a powder dispensing die set for 4.2 gan Tightgroup for my .38 Special loads, and published data is a bit higher than I get out of my pistols over a chrono , I will start there in building a load for our Wild Bunch Nationals in May.
