This is a great single cavity grease groove mould for silhouette, mid range or long range shooting. Works very well with 45-90 through 45x2 7/8" caliber rifles not recommended for 45-70 due to lack of powder capacity. We recommend a twist rate of at least 1-17" but we have had good reports of this used in a 1-18" twist barrel. .459" diameter, bearing surface length is .688" with an overall length of 1.500".
