Per Berry's website FAQ......
Plated bullets occupy a position between cast bullets and jacketed bullets. They are soft lead, but have a hard outer shell on them. When loading plated bullets we have found best results using low- to mid-range jacketed data in the load manual. You must use data for a bullet that has the same weight and profile as the one you are loading. Do not exceed mid-range loads. Do not use magnum loads.
As an example that is similar but NOT the same
as your bullet weight......I am using Berry's 115 gr. round nose in my 9mm 5" XD. I use 5 grains of Unique which gives me a velocity that is just 24 feet per second slower than 115 gr. round nose Blazer Brass ammo shot from my XD. I set my OAL to 1.150". Again, this is NOT the same bullet
you are using.
Consult your reloading manual(s) using the info provided by Berry's Mfg and you should be able to find a suitable min/max starting point for your bullets.
