Hey guys, I'm quite new to reloading but have read the whole Lee Reloading Manual and several articles online. My problem is: the manual I use doesn't have enough info for me to determine a correct receipe for the rounds I'm trying to load.
I have Berry's 9mm 124gr FP, Unique powder, CCI primers, used brass. I have already figured out that 1.070" is the MAX I can seat my bullets for them to fit the short freebore of my SP01 Shadow.
The powder charge for Unique is at 4.8gr in the book, but for a 125gr round nose bullet.
Problem is, should I reduce the charge in my case, because the bullets are FP seated deeper than the book says??? Thanks guys

What Book?
Hint
You never start at Max Charge

Only make a few and try them,
because you don't want to have to pull 500 rounds apart if you have a problem
 
You have good components. Load some at 4.0, 4.3 and 4.5 and see what shoots best in your pistol. You want to see what cycles reliably and what groups the best.

Something is the low 4s should be about right.
 
Thanks guys! I actually shot my first 50 reloads yesterday and all was good! I ended up loading a batch of 10 with 4.0gr and the other 40 with 4.3gr. I had some flattened primers but no crazy recoil or muzzle flash, at least not more than the stupid Eagle brand 9mm they sell at the range. Overall pretty happy, might end up loading 50 more but with less powder. I'll stick to 4.0gr.
Actually had a small incident, donno if because of the bullets I use (Berry's) but I'm ok... I had a piece of led bounce into my left hand and cut deep into one of my fingers... I retrieved the led and it looked flattened (not fragmented as I initially believed). My guess is it was probably too hot and bounced back off the concrete down range ?!? Weird hah?
