My advice would be to start with a lighter bullet and a fast powder and stay around 1000 fps - Titegroup or Unique, whichever you can find reliable data for in combination with your bullet. Shoot it a thousand rounds, starting at close range, focusing on trigger control, your sights, and not flinching. The FA is an incredibly accurate firearm, but if you jump into heavy loads too quickly you will never know it. You may run into barrel leading issues with velocities that low - or not - depending on the bullet. Increasing your powder charge a bit, or switching bullets, may solve it.
When you've done that, switch to a "moderate" powder like 2400 or IMR4227 with the same bullet; start at the lower end of the published data and shoot that for a good while, in the same manner - focusing on trigger control and avoiding flinching. You have to grip these guns consistently to shoot them well. A loose grip with a big bore will not shoot anywhere close to where it will with a firm grip. These loads ought to be in the 1100-1200 fps category and will start to get your attention (they will also work fine on deer).
Work your way up the reloading data very slowly (as in, take several months to do it) up the data and when you come to a level that you are not shooting well, stop and back down to the level that you were shooting well ... and keep shooting it. And don't lie to yourself. Plinking is fun but shoot on paper every once in a while to see if you really ARE shooting the gun well.
When you're confident and competent with the higher-end velocities with 2400, or 4227 - depending on the bullet chosen and the velocity you are seeking, you might want to try a powder like H110. You cannot load to the "moderate" end with H110 in the same manner that you can with 2400 and 4227. I'm not positive how much you can with 2400 ... I have used 4227 for such purposes almost exclusively. I use H110 for my high performance loads and start loading and shooting it a couple months before hunting season.
I think of it as a "recoil ladder" that you have to climb. There is only one proper way to get to the top of a ladder.
I started shooting a 454 Casull long before I was ready to do so - and jumped right into the heavy loads. Dumb mistake. It took me years to correct the mistakes, habits, and perceptions formed. This time around, I did the above ... 10,000 rounds last year ... and I cannot tell you how much difference it has made.
I am working my way back up the recoil ladder with a 500 Wyoming Express right now. A different world than the 454 Casull ... because of the bullet weight.
