I have been reloading 9mm and ... decided to jump into reloading 45ACP
As others posted, I think you will have hard time finding a better deal than RMR for plated RN bullets.

And if you load lighter target loads, especially in oversized factory barrels, softer 14-16 BHN alloy deforms/expands well even with lighter powder charges to produce accuracy and prevent leading -

MBC 18 BHN SWC (IDP #1) with 4.8 gr W231/HP-38 is one of my 45ACP reference loads but when this load leaded heavily in oversized factory barrel (.455"+) of Taurus PT145 SA/DA, softer MBC 12 BHN SWC (Bullseye #1) with same 4.8 gr W231/HP-38 restored accuracy with minimal leading and even worked well with lighter 4.0 gr Red Dot/Promo that is a joy to shoot in Sig 1911/M&P45, especially compact PT145 SA/DA due to lighter recoil.
And Z-Cast's 14-16 BHN alloy is softer to produce accuracy and with less leading issue with lighter target loads so factor these when shopping around for your bullets.
And for 9mm (especially barrels with shorter leade), Z-Cast is one of few remaining bullet casters offering "stepped" RN bullet with longer, more pointed nose. If your barrel has shorter leade, this "step" will help clear the start of rifling when loaded to typical 1.125" OAL and feed without issues in all my 9mm barrels, even the Lone Wolf barrel with no leade (when other lubed lead/coated bullets with shorter/rounder nose profile won't work).
124 gr Lead RN with 3.8-4.0 gr of W231/HP-38 at 1.125" OAL is one of my 9mm reference loads and 14-16 BHN works well with lighter 3.6-3.8 gr of Promo.
At $27/500 ($59/1000 shipped for 3000 quantity with $15 shipping), also hard price to beat -

For coated bullets, hard to beat Brazos 125 gr Hi-Tek RN at $42/835 ($57.30/1000 shipped) -

With Z-Cast 124 gr "stepped" LRN/Brazos 125 gr Hi-Tek RN and Promo, I can reload 9mm for less than $5/50 ... Can you get cheaper than that with retail bullet load?
Only way you can get cheaper is to cast bullets yourself.
