I have four Ruger revolvers I am looking to get setup for cast bullets and to accurize as best I can. I have slugged the throats and bore of each and the data as follows,
Ruger new model Blackhawk 6.5" stainless .357 magnum. I have had this one a long time and it has some rounds through it
bore .3580
cylinder
1 .3592
2 .3592
3 .3594
4 .3593
5 .3594
6 .3592
Ruger Bisley Blackhawk 4 5/8" stainless .45 colt new and unfired except for factory
bore .4505
cylinder
1 .4523
2 .4518
3 .4520
4 .4523
5 .4520
6 .4522
Ruger Bisley Blackhawk 4 5/8" stainless .45 colt I have 500 or so rounds through this one.mostly informal plinking
bore .4508
cylinder
1 .4522
2 .4522
3 .4522
4 .4522
5 .4522
6 .4522
Ruger Bisley Old Model Vaquero 4" case colored/blued .45 colt bought used unfired by me.
bore .4513
cylinder
1 .4520
2 .4522
3 .4515
4 .4520
5 .4515
6 .4514
I think these numbers are probably pretty good for out of the box guns. the two stainless .45's probably have a bore restriction?
How would you proceed as far as gunsmithing or any fire lapping etc?
What size should i size my boolits? hopefully I can run the same load/components in all three .45's.
Thanks
