Reloading new bullet brand

[arod757]

Do you guys rework your loads if you switch to a different bullet manufacturer but are using the same weight and type bullet, such as FMJs, in both brands?

I only change powder charges if I switch from plated bullets to FMJ's. I tend to load plated projectiles as if they were cast lead.

Same bullet, same wt, different maker- I dont change anything. I confess I am not as particular w/ practice ammo reloads as some are.
Rifle hunting loads are a different story though.

For metallic cartridges, I don't change loads if I'm switching from brand X JHP to brand Y JHP if they are the same weight.

For shotshells, I follow components in printed recipes more closely because we're talking lower pressure (9k-11k psi) and changing 1 component (just the primer, for example) apparently (allegedly?) can have a significant effect on the pressure.
