Hi
FWIW...
Last spring, I recovered bullets that I shot in the snow in January 2018.
- Fire line at 600 yards
- Shiloh Sharps 45-90
- Bullet: Creedmoor 45001, 539 grains. casted tin-lead 1-20 (5%)
- Powder Old Eynsford 1 1/2 , 81 grains
- Starline brass: fireformed.
- Lube: SPG. Newspaper wad, LDPE 0.60 wad
I recovered 24 bullets of which 2 had their newspaper wad stuck at the base. Some had still the lube in the grooves. ( I am not an expert eith the cam ...). Just a few were shorter by no more than 0.015 inch. Most were longer.
Still worth to think to cast 1-16 ? …
