D1 ragebait, any shell with over 480 penetration is fine for top tier, I can pen through leopards and anything else like butter with dm33.
Top tier is all about shooting for weak spots, or flanking. This honestly can be done with 120mm dm23. Really is a skill issue if you need these high powered shells. CL3143 or whatever works great for the centauro 120, and it has similar pen to 3BM60
erm
for leopard yes
for abrums
M833 for M1(also m833 has wrong pen bruh)
M829A3 for stuff like M1A2, HC
M829A2 for M1A1
M829A3/A4 for SEP and stuff above
AIM is missing KE-W-A2 or maybe A3
so yeah theres a whole lot
