So I have a question about reloading for a.308...I have the load data for a 150gr FMJBT but I only have 147gr FMJBT bullets, how can I adjust the amount of powder for the 147gr bullet? Or can I just use the starting load for the 150 gr???

Just use the starting load for 150 and work your way up, if needed.Ronald Reagan once said that the most terrifying words in the English language are: "I'm from the government and I'm here to help".

The 150gr data is fine as the 147gr bullet is close to the weight of the 150gr data BUT just slightly LESS weight. You get into trouble when you try using data when the bullet is heiver than the data bullet. Such as a 180gr bullet with 150gr data.A 30cal will reach out and touch them. A 50cal will kick their butt.
