I carry daily and practice for serious purposes here on our farm. The regimen includes precision shots at 10 yards and beyond out to 25 yards, and speed work from 10 yards on in to 3 yards, and all beginning with the gun holstered.
I use Front Sight's (a training school in Nevada) silhouette for all training with its half circle chest scoring zone (10" dia.) and a playing card sized scoring zone for cranial/ocular shots.
As my range is right out the back door in a side paddock, I shoot nearly every day...10-40 rounds depending on the chores workload. To afford that level of shooting, I cast my own bullets and load for the guns on a pair of Dillon 550B's. Local LEO's also use my range to tune up prior to their qualifications...as a result I have a large store of once fired brass in 9mm, .38 Spl/.357 Mag, .40 S&W, and .45 ACP. My ammunition costs per round are consequently the price of a primer and the powder...less than a nickle for .45 ACP. It's a shooter's dream for sure.
For fun shooting, I have a series of railroad tie plates, ground mounted at varying ranges out to 150 yards...these provide interesting sighting problems for those who've trained only at short range. For family/friend shoots, we warm up on defensive drills, then complete the day by shooting the plates starting at 20 yards, one shot each, shooting at 5 yard intervals...a miss and you're out. The plates are roughly 8x14" on average, and shooting offhand, most guys are out by 45-50 yards. It makes for a fun afternoon.
