This heel type bullet is meant specifically for the 41 Long Colt. It measures a nominal 0.410″ diameter and a nominal 195 grains. It can be sized to your preferred diameter. After loading you will need to lubricate it, and the liquid Alox by Lee (see Higginson Powders) is ideal for this application. The bullets have a BH of about 15 and will swage down while providing a good grip on the rifling to avoid leading. The price is per 50 bullets. The shipping weight is 640 g.
