[Tokoroa Cast Projectiles]

Ok, great info.
The only fast powders I have are;
AS50n & Unique. Both pretty similar speed wise.

So,, filler is just an old wives tail?
And since they are fast should be ok to drop down to say, 3 or 4gr?

With cast bullets nearly everything is old wives tales and voodoo, unless it is stuff you have done personally doubt it,
drop your load in small increments like 2 tenths getting a stuck cast bullet out is not that hard but a jacket gunsmith only
Subsonic with jacketed is a waste of time unless using the new specially designed ones
Cast bullets are good hunting projectiles, at velocities from 1200 to 1800+, to get more power increase the bullet diameter
.30 cal is really the smallest to consider stepping up to .35-.38 is better with bullets 200 pus grains
