Just received an old Model 15 in very fine shape. Bores look great in and out, and ring true. I plan to shoot it with BP handloads no heavier than 1 1/8 ounces of shot, and up to three drams of powder. But I want to put a couple of heavy BP loads through it just for insurance. Does 110 grains of FFg (about 4 drams)and 1 1/2 ounces of shot sound like a reasonable load for this purpose? I surely do admire Sherman Bell, but I wouldn't want to run Remington Nitro proof loads through this nice old Swede.
