I just scored a Uberti 1885 High Wall in 45-70 off Gunbroker so I'm getting back into the fun and games of black powder cartridge rifles--many years ago I had a Rolling Block in 40-70 SS that I loaded for. This rifle will not be used with smokeless, it's BP only as far as I'm concerned.
Any advice as to creating the load stack in terms of lube cookies or lubed wads, powder compression amounts, and over-powder wad types and thicknesses that seem to work well as a good starting point for a stock Uberti?
I've done some searching on here and on a few other sites, and it seems that the longest bullet the 1:20 Uberti rate of twist will stabilize is 1.57" in length (according to the Greenhill Formula), and I've read recommendations that bullet weights shouldn't go much over 500 grains in that rifle in order to be adequately stabilized, so I'm probably going to lean towards slugs between 400-500 grains.
I'll definitely be slugging the barrel and doing a pound cast to get the bore/throat dimensions, so I'll have those dimensions to work from in terms of bullet fit.
Beyond the SAECO 645 and other Postell variants, are there any particular slugs those of you shooting the Uberti High Wall would recommend trying out? How do flat nose bullets like the RCBS 45-405 or 45-500 typically shoot in the Uberti?
I don't intend on shooting any further than a few hundred yards as I'm not in an area where there's BPCRS matches, and I'm doing this for fun and to hunt deer. On the farm I hunt, typical shots are under 150 yards, although there are places there where I could take much longer shots (500+ yards) if I wanted to.
