GMA 505-17500

AHR gma action-7,000

AHR custom cz-5000

Ritterbusch 505-17,000 which he makes great working rifles even 1 that feeds the 577 nitro express

and one of my favorites

Satterlee arms-14,000 imo better then gma

also

Heym 505-10500

Will report on the bitterbusch 577 when it arrives

Also the 500 A2 is just a 510 wells express under a different name necked up 460 weatherby there is the 505 barnes supreme which doesnt need the magnum mauser action 460 necked up to 505 but if you want a great caliber and you load your own ammo id go 460 guns and ammo 404 jeffrey necked to 458 hits harder then the lott but not as much as the weatherby
