  1. With 165's you're running a little over 1000fps for basic major. Speed of sound/blast is about 1200fps. A blast shield in front of the chrono may be the answer. Use a target/piece of cardboard with a 4x4 hole that lines up with a plane about 4" above your sensors. 2nd guess...light angle. Chronoman
  2. One of the best things I've found to spot and self-help correct is a Mpg or video of you drawing/shooting. People can "tell" you all day long and it won't register where actually seeing what you are doing can confirm to your eye what you are or are not doing right. C-class draw to A zone hit=1.5sec. An old shooter once told me "No match was ever won from the holster" I'll add that they can be lost there by not having a good grip...and dropping the gun.
  3. Back in the day, the Chronograph state was treated as a Back-Water/leper colony where the sick and lame RO's ended up and various bad procedures happened. Over the past 19 years that I have been running the Chrono Stage at Nationals and various Area and local matches, I've done my best to promote the Chrono Stage as an intregal part of the match where shooters can expect a fair shake. We've standardized equipment, the use of a chrono coffin, artificial lighting for consistent lighting throughout multi-day events. I've written a Chronograph Compendium that's available for the asking and these standards and practices are printed in the Match Director's handbook. To my delight, horror stories about the chronograph stage have declined over the years. The price of a good chronograph has come down to the point that it's not unusual for several members of a given club to have one. Even small clubs can afford a chronograph for general use of club members. Sunlight is the biggest offender with chronograph use. Light intensity and angle. By using a chronograph in a box with artificial lighting, you've got as near to laboratory conditions as you can get without temperature control. Got a chrono issue? Drop me a note. btw, any major match worth it's salt will have a chrono set up for courtesy checks before competition starts just in case someone needs to make a quick trip to WalMart for a couple boxes of Blazer.

  4. Having used both Oehler and CED I find I prefer CED. The Oehler 35P's we used earlier with USPSA Nationals were plagued with sticatto error messages whenever a small generator was used near by. They didn't have any computer interface and support from Oehler was minimal. The current generation of CED has processors that outrun incandescent lights and if artifical light is needed, it has to be DC--not a bad thing. I presently use an inverter to power the lights from my car...no batterys to recharge. CED's have been proven by independant radar labs to be .5% more accurate than Oehler (the top two), not that pistol shooting really needs that kind of accuracy but it's nice to know. CED's customer service is equal to Dillon. 'nuf said on that. CED supports Practical shooting with 3 complete sets for every Area and above championship match for the US. The affected clubs can keep the equipment, sell it, raffle it off, or put it on the prize table. If you have an issue with one of their chronographs, it's not uncommon to talk directly to Charles Hardy, owner of the company. They are also one of the most economical chronographs on the market. Mr Hardy occasionally sends out requests for product improvement...brain storming ideas. The wireless connection has been suggested. I will admit that the hardwire connedtion to the sensors is problematic at times. Chronoman
  5. In times of need, I've used 2 SureFire flash lights just balanced on the outdoor sky screens in an indoor range. Chronoman
  6. Crimp enough so that the bullet doesn't push back into the case when you push it against your reloading bench edge.
  7. Covering the screens with a translucent material will give more accurate/consistent results. As an aside about CED's newest chrono's, they can NOT be used with incandescent lights any more. Their new processors are TOO FAST and pick up even the flicker of incandescent bulbs. In a pinch, I've used SureFire flash lights. New Email address: Mygunwerks@Gmail.com Chronoman
  8. You might do the same thing as when traveling to Canada...Install a pop-rivet before you cross the border. A pop-rivet is considered "permanent" where an internal block is not since the mag can be easily disassembled to remove it.
