7-6.5 PRCW loads: Lapua vs ADG

[WallyM]

I've been loading 7-6.5 PRCW using Lapua 6.5 PRC brass as the parent case. My brass has been showing increasing signs of being worn out, I am switching to ADG 7-6.5 PRCW brass. ADG claims that downloading is typically required for their cases vs Lapua.

My question is: does anyone have any experience switching between these two cases?

My current load for Lapua brass and 180 Berger Hybrids is 55 grains N555 over F210GM primers.

Thoughts on load changes for the ADG brass?

I have only used the ADG brass. I run a 32” 8.5 twist bbl . At 55.7 gr 555 I get about 2880 fps . At 56.2 speed increases to 2915 fps. I tested up to 56.7 gr 555 . Speed was 2950 fps but clickers showed up after 3 loads. The 2880-2915 area shot well and clickers haven’t been an issue after 10 firings.

Thanks that's good info. I have avoided going above 2820 because of occasional clickers. It sounds like it's reasonable to load at or near what I would load with Lapua.
