[QUOTE="RockyMtnMT, post: 1285236, member: 7999"] We use the MS now all the time. We develop with it then remove it for range testing. If there is any change to the load during range testing then we will shoot it over the MS again to confirm vel. Using it makes you do your vel testing separate from range work but we have found that we shoot far less shots this way than we did with a sky screen system. Vel data is now much more accurate and takes out the doubts. As far as ES goes it is very easy to get carried away with focusing on it. It is not always the best indicator of accuracy. Don't get me wrong, I like to see it as low as possible. It is pretty tough to shoot the difference between a 10fps ES and a 30fps ES. I won't throw out a 30fps ES load just based on that. It does not surprise me at all that your lowest ES loads are not your best accuracy loads. For me the MS gives more reliable data than anything else that I have used and takes away one of the variables when figuring out long range drops. I no longer make vel changes in my dope to get things to line up. I will adjust bc until I get drops to match up as close as I can to field data. Then you only have to worry about dialing consistency in the scope and sliding bc's depending on the vel of the bullet. They all vary as the vel changes and it is just a matter of finding the one that hits most consistently with your field data. Same bullet in different rigs will often give different field data. My recommendation is to run the MS and don't look back. Steve [/QUOTE]
