An older friend who has passed away now built me a 577 on a 10 gauge action. It’s ugly but it shoots good . It’s regulated with 90grs of varget and a 650gr bullet. He called a nitro for black load.
Looking forward to seeing your photos. The nice thing about the larger bore double rifles is that they don't seem too picky about what you feed them. I have had good luck with Varget and cast 650 grain bullets in mine for reduced loads, but the one that stands out is 75 grains of IMR-4198 and 590 grain cast bullets. It will shoot these to exactly the same POI as my full house loads and will put 4 into two inches at 35 yards.
Hi Jon,
I saw your post for the .500 NE cases. Are these all brass or are they nickel plated? Hard for me to tell... sorry.
Thanks,
