Yes, the complete base. I acraglassed my complete base to the receiver recommended by my smith. I'd tell you If you don't have any bedding compound To use lock tite red and completely cover the complete bottom of your base and screws. I used lock tite blue on my base screws when I acraglass bedded the base. It's up to you which product to use but you will want to litteraly glue the complete base to your receiver. I will tell you your never going to get the thing apart again with lock tite red. If you ever think your going to remove it use blue. Red is permanent, which that rail never needs to come off anyways.
There is not a lot of contact surface between your base and the receiver. The lock tite or acraglass will fill in the voids.just clean off the excess that oozes out after you have it torqued in place with some Q tips and rubbing alcohol. I'm sure when you remove your base you'll see wear marks on the edges like mine did showing you how little it comes in contact with the receiver.
And make sure you degrease the base, screws, and threads in the receiver being any oil will brake down the lock tite and it will come loose again.
And just remember all guns are different so work with starting loads in .5 grain increments and check for pressure signs. Had a few posters tell me on other forums they can't load the Lee 300's as long as I do so a shorter OAL is going to build higher pressures quicker.
