I just worked me up a load I really enjoy shooting:

Rainier 124 grn copper plated hollow point.
Winchester 9mm brass.
CCI small pistol primer.
Bullseye powder 4.6 grns.
OAL 1.135

This load cycles my auto and is very accurate.
Please comment on what you think of this load.

Looks to me like you are at or maybe slightly exceeding max loads for 124gr plated.

I can't find the exact load you are using, but Lyman says the max bullseye for 125 gr Jacketed HP is 4.5gr. Since you are using plated bullets I would say you are pushing it a bit.

From Rainier:

We, at Rainier Ballistics, recommend using lead bullet load data when loading our bullets. There is no need for adjustment when using lead bullet load data. Our bullets are jacketed using an electroplating process and are softer than traditionally jacketed bullets; hence the recommendation to use lead bullet load data.

If you only have access to traditionally jacketed load data, we recommend a starting powder charge directly between the listed minimum and maximum load, and you may use published load data found in reputable reloading manuals.
From the data I have you are over Max with lead data and also with most jacketed data. I think you are to hot for those plated bullets. JMO.
