450 BM subsonic load data
Posted: Fri Mar 28, 2014 8:16 pm
Hi Guys.
I have built a couple of bolt action 450 BM rifles, 12" barrel with suppressor.
I want to run 225 FTX or 300 XTP subsonic.
Can anyone help with some load data please or a starting point.
I have searched but haven't found data for such light projectiles.
PS, I have been loading for years & load everything from 22 centre fire to 50 BMG including a heap of wildcats.
I have plenty of powder from Lil gun etc to VV 20N29
Thanks for your help.
Cheers Greg.
