yup
here is the website! I love it!
http://www.neconos.com/details3.htm
btw...I goofed up by indicating 22" barrel for the gun. Add about 50-60 fps to the prediction.

Craiger!........................Back on 10/16/07 under this same "reloading" section, posted by "quitgary" on this site (page 6), he inquired as to the performance of IMR`s new 4007 SSC in the 300 WSM. From there you can click over & read someone else`s comments regarding the new IMR 4007 and how well it performed in his 300 WSM rifle!................According to his comments "Sam Spade" if I remember correctly, his bullet holes were consistently touching each other during each charge level while working up his loads to maximum!!..........I am using up what I have, but I will have to try this 4007 SSC in my 300 WSM! According to the data I`ve seen, 60 gr. is about the max., but the higher velocities can be achieved using on average, 10 grains less per round with the 4007! Also according to Sam Spade there were no pressure signs in his rifle at the 60 gr. charge level.............IMR has a press release about the 4007 on their site. The burn level falls in between 4320 & 4350. Hodgdon on their site has reloading data for IMR 4007 too!..............I am certainly looking forward to trying this powder out! If it gives nearly the same velocities as the slower burners, is more accurate, while using less in the process, then that will be my go to stuff!

POP!!!...........................I had a feelin that you would be sending some IMR 4007 info!!! Good jobby! I`ll be sure to refer to that info too!!...........With the faster burn, I wonder if the 4007 will be just a little more efficient in my shorter barrel??......................Thanks for the info!

Rick Smith has posted a excellent load using IMR 4831...a excellent load and powder in the 300 WSM.
Using IMR 4831 I have obtained top Vel and accuracy.
Anorther good powder is MAG PRO @ 75.4 with 180 TSX and Fed 215GM primers in FC Cases with a COL of 2.825". I am getting 1/2" groups out of my Win 70.
