20 Ga Paradox style load data

[Cast Bullet Engineering]

Gentlemen,
I'm looking for some load data for a 530 grain Paradox style cast bullet in 2.75" 20 ga cases please.
Bullet diameter is .625" and and being fired from a fully rifled barrel on a big Martini action.
Could anyone steer me in a direction to get me started please?

Depends on what powders or equivalents you can get there. and

are cases plastic or brass, Only loads I tested

are with rifle powders and the real slow shotgun powders.

Alliant Steel, IMR4759, VV 110 and RE17. ..Ed

Mayber that doesnt help you since you asked abt 2.75" hulls. Sorry. But the addition or subtraction of 1x1/2" cork wad shouldnt change pressure that much. Still, be warned that that would make this an untested load. be careful. i just wanted to list a possible place to start looking for you.

But, where are you getting your slugs?
