Well I have a few numbers to start with but I was not able to graph past 100 yards because of the wind today but I will test out to 300 yards as promised. Sorry it took so long for even this data but with work and being sick the last few weeks it has been hell to say the least. Well I am using a 7mm STW in a REM sendero with a 9 1/4 twist. This rifle as over 1500 rounds through it so I was really happy at what I have found so far. I am not going to give a bc but if some one wants to figure it out with the numbers I give and post it that is fine. I will also add pic of targets later after I get them off the camera. Here is what I found today. At the muzzle I was getting 2859 FPS with a ES of 12 and a SD of 6. This is with 5 shots. Now at 100 yards I was getting 2713FPS with and ES of 5 and A SD of 2. The Elevation is 853ft the Temp was 72 the Pressure was 29.99 the Humidity was 70% and the Dew point was 61. I used a Pact Pro for the testing. I think a person could get away with a 9 twist with these bullets with a faster 7mm. I will really put this to the test when winter comes and I shoot them when it is below zero. I will probably add pics later tonight other wise monday as I have a wedding tomorrow that is 5 hours away. I would like to thank SSCoyote and Richard Graves for sending me the bullets to test!!! Hopefully I can get them tested out to 300 yards this week.
