Does anyone have any load data for this bullet in 300 win mag. My manual only goes up to 200 grain. Data for a 220 would be nice too. I use reloader 22.

The Sierra tech line is a great resource for handloaders and shooters.
Having said that, the 5th edition of the Sierra manual provides loading data for 240 gr MKs in the .300 Winchester in two parts. The standard data for cartridges with OAL of 3.535" with Re-22 is from 61.1 grs (2500 fps) to 66.7 grs (2700 fps). The second part is for a chamber cut with a long throat allowing an OAL of 3.6" and the data for Re-22 is 64.3 grs (2500 fps) to 72.1 grs (2800 fps).
The data with Re-22 and the 220 gr MK is from 64.3 grs (2500 fps) up to 68.1 (2700 fps)
