Went to the range today with my LW Commander and full size and I tried, for the first time some Power Pistol powder. I had 5 rounds of 7.4 grns and 12 rounds @7.0. I was shocked at the way this powder reacts! It is a hot powder with a lot of muzzle flash. Recoil on the 7.4 was hotter than a factory load and the 7.0 is very comparable to factory loads. From now on I am going to limit my loads to 7.0grns. The COAL was 1.255 and using lrg. Winchester primers. ONE MORE THING: Today I had a squib load using Titegroup powder. I was shooting my LW and it would not go back into the charge position. My first reaction was to change out mags which I did. After several attempts I tried the same rounds in my full size Commander and they had no trouble discharging nor loading. At first I thought I might have broken my recoil spring. The lighting isn't good at the firing line so I went to the gun shop and talked to Red the gunsmith. We tried to load a factory round and it would not go into charge. Then we stuck a light down the barrel and both seen the squib round. Thankfully it only went down the barrel less than a half inch and would not let me load back into full charge. I WAS LUCKY!!!! These were loads that were loaded on a single stage re loader and somehow I missed charging a round with powder. It goes to show, that no matter how many rounds you load, mistakes can happen. Somehow I had missed charging that 1 round and that could have caused irreparable damage. I told my wife when I got home that under no circumstances, when I am at my loading bench, do not do anything to distract me. YES, it was MY fault and I won't deny it. But when reloading, caution must be observed at all times.
