  1. I still see a lot of people wondering why they fail to meet PF at a match. If you just add a few extra power factor points, now you know what can happen. The bottom line is that velocity is random in nature and the BEST way to understand and manage it is to use statistics. You don’t need to have any special math skills. This post provides the simple steps to follow. For the why and more details, see Frontsight Magazine, Jan/Feb 2015 Edition, Pg. 70. The standard deviation (STD) measures the amount of variation (uncertainty) around the average velocity and it should always be used when r
  2. In preparation for several major matches in the area, a club performed a chronograph check at a local match last weekend. About 6% of the competitors failed to meet their declared PF. This included several experienced competitors. So remember this! The average velocity (and hence PF) you measure at the range will always be better than the official USPSA chronograph results. Yes, it is true! The two measurements are like comparing apples and oranges. It has nothing to do with the small differences between chronographs and of course all the laws of physics apply equally in both cases. So
  3. New to the reloading game here so any advice would be much appreciated! I am wondering if WST can safely make major PF out of a Glock 35 with a 180gr .40 due to the case pressure loading WST short in a not fully-supported KKM Barrel. According to Hodgdon reloading data with 4.9 grains of WST you are theoretically making 932fps, almost a 168PF, but at 32,000psi. However that load data is out of a 4" barrel vs a 5.3" of a G35. I have been doing a little research and have found that with a KKM barrel many can run an OAL at 1.135". Can I load safely to say a 170PF?
  4. I am trying to develop some reduced recoil loads for 3 gun. Unfortunately it’s still hard to come buy some of the more popular pistol powders so my selection is limited. I have on hand Silhouette, Accurate No. 5, Power Pistol, and CFE Pistol. I would love to find some NV320 or 231. I am using 180 JHP Montana gold bullets. Looking through several different loading manuals all of the minimum loads are still close to major PF velocities. I see several threads on here where people are loading up to 1 grain under the minimum recommended level. Is this safe? Can i start a minimum and back it of .1 t
