Looking for a source for this bullet specifically for a Winchester model 1876. Don't really care about the weight, but I wish to utilize the crimp groove and it seems to be specific to this rifle model. I have bought 2 different projectiles that when properly crimped would not cycle through the action. I went so far as to turn the bullet in a lathe to remove some material from the meplat to shorten the bullet but that is more effort than I wish to expend. Seems to me with the recent availability of 1876 reproductions in 45-75 there must be casters producing this bullet. Any help appreciated.
