You need to see what your barrel likes. When I was having problems with my gun here is what was suggested to me and it worked great.
Load multiple batches of rounds, to an OAL of 1.175, 1.180, 1.185, 1.190, 1.195, and 1.200.
Load only 10 rounds of batch #1 in a mag... Lock the slide back and with a black Sharpie marker, color the feed ramp black. Then load the mag and shoot all 10 rounds. Then examine the feed ramp - the goal being to have the bullets contact the feed ramp as high as possible.
Then repeat for each batch of the different OALs.
