[QUOTE="J E Custom, post: 339144, member: 2736"] [b]Re: Reliable Chronograph Readings[/b] Well said !!!! The reason I recomend the use of a chronograph is to minimize the number of loads I have to work up. I have loaded hundreds of loads trying to find a good Powder,primer, bullet combination without the use of a chronograph and then decided to run some through my chronograph and withen 4 or 5 different combinations found a load that showed promise. and then focused on them and found "the load". I now test all loads through the chronograph and eliminate the worst and use the best for the final testing. I have a Oehler 35 P and have compared the velocity/trajectory against the balistic tables to verify the accuracy of the chronograph and the proof channel and they are spot on. I have found loads that have low SDs that still would not shoot well but buy changing the seating depth they tightened up and at long distance and did not string vertically as mentioned. Again, at short distance SDs are not very important but at long distance they are. As to the actual velocity that is not as important as the SDs ,So if your chroney is not dead on so what, it will still tell you if you have a good load to work on. Just my 2 cents J E CUSTOM [/QUOTE]
