Does the Hornady 9th Ed. manual (H9) not mark when loads are compressed loads? I'm starting to load .30-30 and was looking at the data for LeVeRevolution on Hodgdon's site vs. what's listed in H9. Hodgdon's site and the canister both list the max load for a 160gr FTX as 35.5C gr. H9 lists the max load as 37.0gr. Both claim 2300fps as the velocity for that charge.

Hodgdon's site lists the min load as 32.0gr while H9 lists min load as 27.7gr. So 1.5gr variance at the max end is a fairly significant one here and the min end load is 4.3gr??

I know that Hornady's load book is reputed to be on the "light" side of loads so I was very surprised when their data was a significantly heaver one vs. Hodgdon. Also, since Hornady and Hodgdon supposedly worked very closely together on the powder, I'm surprised there's any data difference at all.

Anyone else notice this or have any ideas? I'm going to e-mail Hornady and ask them about the discrepancy.
 
Compressing powder is perfectly fine if there is load data to support the charge.

Many handloaders (me) prefer Compressed loads for accuracy and consistency. Compress away, you will be fine, just start low and work up as always.
 
Sorry, to be clear, I'm not concerned about creating the compressed load in and of itself. What I'm concerned about is the varying amount of powder behind what is presumably a compressed load (i.e. the 1.5gr difference) and the fact that Hornady 9th Ed. doesn't seem to list the load (or any load??) as being compressed beyond a certain point.
