I keep my loads to military specs or actually a little lighter. I only load 30-06 for the Garand and use only 4895 plus a 150gn M2 bullet. How critical is it to have a Chrono or is it just one of those neat little gadgets I'll end up getting later to look "cool" to my friends?

I use my Chronograph for two purposes:

1. An objective measure of what the componets that I am using are doing. All too often I found that I couldn't tell the differnce when I changed a variable in my loads. I also found that similar loads gave me different in different guns. Never would have known with out my Chrony.

2. Catch problems with my reloads. I shoot over a thousand rounds of 9mm a month, one of my goals is to make sure that my reloads are consistent. They have the same recoil and shoot the same place each time I pull the trigger. While the holes in the target tell me if I am having a problem they don't tell me why. By chronographing my rounds it CAN eliminate some of the variables that might cause inaccuracy.

KJM. We all want to look "cool" to our friends, right? Seriously, how do you know you are actually reaching "milspec" with your ammo? The book may say X gr. of IMR-4895 will give you say, 2800 FPS, but are you really getting that velocity? You might only be getting 2600 FPS, or maybe? Oh heck, pick a number.
If you only load 30-06 with one bullet, and the load is working well for you, you may not need a chronograph. If you are loading more than one cartridge though, it might be worth your while.

Let me add a little here too. If you do alot of case preperation this will have change up things as well. Something like primer pocket uniforming and deburring the flash hole makes a big difference. Also if the cases are freshly trimmed to length. Any one, or combination, or all of the above will change what you think you are getting,and with a chronograph you will know for sure what you have.

kjm, Good post above. The main reason to have or at least have access to a chronogaph is that you don't have a clue as to what you are doing with your reloads.
An Oheler 33 was one of my first investments in reloading equiptment when I got into rifles.

Since we're on the subject of chronographs, I would like your recommendations on a good, quality chronograph with the following criteria: 1) Priced at $150 or less, and 2) Have a handheld display away from the main unit. The ability to calculate averages is not needed, but being able to record a string of shots is. A printer is not needed. Thanks.

You don't really need one, but it certainly completes the picture when reloading. Once you use one, you'll "need" one after that.

My latest Midway catalog has the Chrony Master Beta for 109.00, shipping included. I purchased the same model in December for 129.00.

"MasterBeta"? Oh, sorry, I thought you meant something else about something one might do in the privacy of their own home... :-)
