Please advise what loads-- [gr.] you would recommend for these 2 bullets while using “Accurate No.5” powder: For a Smith + Wesson MP9 compact. a 9mm....

[1] 115 Gr .355dia FMJRN Hornady

[2] A 122grs. FPBB from Precision Cast, this is a hard cast lead with a high Silver content at .356 dia. It’s a plain base –round nose/flat point.

A BiG thanks for your time trying to suggest a good starting point for theses 2 loads.

High Silver content huh?
Expecting Werewolves?

Seriously, I doubt they have much if any silver in them at all.
Probably lead, tin, and more antomeny to make them harder.
Silver is way too expensive, and has way too high a melting point, to add to bullets.

As for loads?

Accurate Arms Co. recommends for AA#5:
115 = 7.6 MAX Load.
124 = 6.4 MAX load.

Reduce both 10% for Starting loads.
In other words, 6.8 and 5.7.

Hornady recommends with AA#5:
115 FMJ-RN = 5.6 start - 6.6 MAX.
124 Lead = 5.3 Start - 6.2 MAX.
