Before cooper of montana sold to nighthawk customs I had recieved load data from them for their 300 win mag and I cannot locate anymore and I am hoping I can maybe find someone on here that might have that data and would be willing to share it.

The test target on my 300 WM from Cooper was made with 168 gr Sierra Match King and IMR 4350

I have also had good luck with the following loads:

165 gr Nosler Ballistic Tip w 71 gr Reloder 19
200 gr Nosler Accubond w 67 gr IMR 4831

Thanks for the info. I was trying to come up a little bit of a shortcut for a 200 grain bullet but haven't been successful guess I'll just have to do the ol ladder test and go from there. Got the 168gr card myself and have a decent load for that already just trying to get my standard deviation down and might just not need the 200 gr option.

How can anyone shoot a 3-shot group like that being kicked by a mule (aka a .300 Win Mag)? Impressive...
