.303 brit was cheap, so was 762x51, for a while. I used to get 762nato for about $120/1000, now that is only a memory.
I do a lot of casting(the pot’o lead is warming as I type) and was temped to try some molds that are intended for .30 carbine in the tok. I just like to have dies for most, if not all, of the calibers I have....excluding .22rimfire.
Those Hogue grips do look nice. I just used some of the fusion black paint and painted mine. Not as classy as the wood but much better than the redish/brownish color they were.
