New to reloading. Loaded up my first batch of .308 168 gr Sierra Tipped Match King. Used the Lee Manual for load data. Lee manual indicated a maximum of 45.9 gr of IMR 4064. So I loaded up five rounds at 42 grains, five at 42.5, and so on, up to 45.5 grains.

Just happened to come across the Sierra manual which indicated a maximum of 43.6 gr of IMR 4064 for 168 gr. BTHP. Not exactly the same bullet, but real close.

This 2+ grain difference seems like a lot to me.

Anyone else experienced this situation?

Good to Go with the load from the Lee Manual?

Thanks in advance for your input.
