450/400 3" Regulation Load ?

[Frederik Badenhorst]

Hi guys

I would like to hear if any one has a load that they are willing to share mimicking the standard Hornady factory load in this calibre?
I recently purchased a Verney Carron double rifle which has been regulated for this ammo and just wanted to see if I could get a ball park load to start of with.
I am using Hornady brass and Woodleigh softs 400gr.

Any advice would help.

Cheers
