pushing 40gr vmax with H335

[dave338]

Hi all
anyone pushing the .223 with 40gr vmax to max fps using H335

load books are quite far apart with data , what have you used that worked at max fps

sierra max 29.1gr = 3700
lyman max 28.3gr = 3640
hornaday max 27.4gr = 3700
ive gone much faster with n120 , but h335 meters perfectly through the harrels, would speed up reloading !

Re: pushing 40gr vmax with H335

Hodgdon says 28gr max, so I'd work up to at least that. I haven't tried 40 grain bullets, but I'm right around what Hodgdon lists as max for 55 and 69 grainers. I really like H335 for progressive loading, but if you get near max watch it in the summer as it seems to be somewhat temperature sensitive.
