I have noticed something strange is the Hornady 7th edition manual.

This seems strange to me. I have noticed in the Hornady 7th edition reloading manual that the lighter the bullet the more powder it uses. Most of you know I am loading for the 22-250. For example the 40 grain V-Max It takes 37.00 grains of IMR 4064 to push that little bullet to 4,100 FPS. That is a max load. Now for a 60 grain V-Max using IMR 4064 the max load there is 34.3 grains and that pushes the bullet to 3,500 FPS. It just seems strange to me. You would think the heavier bullet would require more powder not less. Now there is a 600 FPS difference in velocity. I guess that is because of the heavier bullet and a smaller powder charge. It would seem to me that ( I would never try it ) you would be able to load the 60 grain V-Max with the 37.00 grains of IMR 4064. Is it because the heavier bullet causes more pressure? I don't know I would not do anything other than what the book says. I am new to reloading and this is just me thinking out loud. Thanks and take care Dale

Dale,  powder wt going up as bullet wt goes down is normal

what is strange when you see the opposite.

The heaver the bullet the greater the pressure, not knowing what round you are talkin about look at the pressures @ max loads for each and you will see that it goes up with the bullet weight.

I noticed I did not include that information in my first post and it is now corected. I am loading for the 22-250. Thanks Dale

Also, the heavier the bullet, the longer it is, so more of it goes down in the casing when you make it certain max length, leaving less room for powder. That's usually where you see it listed as a compressed load, although I haven't seen many for the 22-250.
