PP bullet

[jtex54]

Looking to get another PP bullet mould for 45 / 2.4 and would like some advice on the 2 dimensional type that are available from Brooks and others. These nose pour bullets have a .450 base and taper to .441. Trying to get my head around how these would fit into a sized case and engage the groves if they are .459 after patching. Do these work in standard Shiloh bore/chamber?

Any experience with these would be appreciated.
