The 45-70 loves the Lyman 457193 sized to .460 over 28.5 grs of SR4759. One ragged hole at 50 yds. Will load more and try at 100 yds next. The Sierra 400 JSP over 19 gr of 2400 did the same. The 45LC definitely likes heavier bullets. The RCBS 45-300-SWC does well and better than the 255 gr. Different loads were well within 1 1/2" and sometimes under 1". 45 degrees today but dry for a change.
