H335 is pretty good. Only thing to watch out for is the muzzle flash from a stiff load! Everytime I pull the trigger everything flashes orange in my scope. And everyone close by checks their eyebrows are still there.

I've also found that the cheap murom primers give better results with h335 than the cci400 primers (which work better in 2206h loads). Go figure.

Anyone here tried N133 powder, talking to Google, it appears to be what folks use for speed in 223.

A mate of mine has some 2206H, so I might pinch some of that.
But if that is still a bit slow I'll give H335 a whirl.

HI Beetroot
I a using N130 in my 222 23.1 g with a 52g match bullet getting 3347fps, this is with a match chamber and a 26 inch barrel.
Usual disclaimer safe load in my rifle etc

I think I'm also going to start playing around with seating depth also
