How much do you adjust the load for bullet width ?

[Sudsy]

Example, I'm about to roll some loads of .308 Win using IMR 3031. It calls for  40.2 gr of powder at the low end and a top load of 43.5

The loads listed are all for .308 diameter.

My bullets, IMI swaged metal jacket BT 148 gr, are .309 diameter.

How much less powder would you use when starting at the lower end of the load data and again at the high end ? 

 

Also, I'm only using the 3031 to get rid of three pounds I've had around (one unopened) before cracking my 8 lb keg of H4895

If anyone wants to trade for the 3031 I'm willing

Russian bullets usually have lesser tolerances could range from 308 to311 at .309 I would start at the minimum load and chrono if you can

IMI is Israeli Military Industries and they're pretty balls on 309

Can you run those bullets through a sizing die?  I always use a sizing die on my reloads. I like CH4D dies.

Also, I would use Varget or 4064 for the 308 Win.
