I just bought an FN commercial spotter (98 pattern) and slugged the bore. I have the discontinued RCBS 82020 mould which has a long nose section that measures .304. My groove diameter is .3095 and I intend to start out sizing them .310.
The diameter across the lands is smaller than the .304 nose so I will have to seat these bullets quite deeply in order for the round to chamber as the nose is not small enough to "ride" inside the tops of the lands. Is this customary? I am assuming it is and that there is no harm when there is a significant portion of the bulled that is deeper than the shoulder/neck junction.
I don't know what my diameter is across the tops of the lands but I suspect it is in the .290-plus minus something range. A cast bullet nose doesn't come close when I try to start it in the muzzle just as a test.
I've just never cast for rifles before and the above issue obviously never came up in the thirty years I've been casting for revolvers.
Thanks everyone.
