I cant get it any better

Kenny.

That alloy I used for that bullet in the .45-2.4 using 81 gr of 3Fg Olde Eynsford powder. That alloy would not stand in your 100 or 115 gr load in the 2-7/8 like it does for the load I shot it with. I ran alloys from 1/20 to 1/14 and some had tin, lead and copper alloys and they all reacted differently as far as nose setback and expansion that had a positive effect on how the lands engraved the shank. The 1/14 T/L and some of the triple alloy bullets did not engrave the lands 360 degrees around the shank for the .45-70 loads.
But anyway that bullet above had a mix of 19# lead and a 1# roll of no lead solder that had 95% Tin, 2% silver, 3% copper.
I had short shallow land cuts using 2F OE.
