Here's a weight/size chart for RB,all weights based on pure lead.

CAL.         GRAINS        GRAMS          SIZE mm
.390           89                5.77             9.906
.395           93                6.03            10.033
.433          122               7.91            10.9982
.440          128               8.29            11.176
.445          133               8.62            11.303
.451          138               8.94            11.4554
.454          141               9.14            11.5316
.457          144               9.33            11.6078
.490          177              11.47           12.446
.495          183              11.86           12.573
.500          188              12.18           12.7
.530          224              14.51           13.462
.535          231              14.97           13.589
.562          267              17.3             14.2748
.575          286              18.53           14.605
.600          325              21.06           15.24

As a rough guide if you dont have digital scales a Bisley Magnum .22 pellet weighs 1.4 grams so 10 weigh 13.7 grams,just gives a rough idea how heavy your finished balls would be.
