Thank you very much !! I appreciate it.

243 looks perfect. I maight have a question to 8x57. Bullet what you have used in calculation is little bit different. I have this one : http://www.hornady.com/store/8mm-.323-170-gr-RN/
weight is the same, but its different diameter. IS it ok ? Can I use 0,321 data to load 0,323. Sorry for asking, I am new guy here. I want just to be sure, before I do something wrong..

thx
