Thanks guys for all your insight. I started the loads at 22.5gr of H335 and worked up 3 rounds of each to 24 with .5 grain increments. This seems to be a safe starting point as you've said / shown in your manuals and mine also that most starting data begins at 23gr. I have yet to get to the range to test them though.

I did notice that Hornady does have you seat the bullet approx lower than (.03) than the Lymans 49th edition which would in essence give the bullet more pressure. So that is probably why they have lower powder charge loads.

Let me know what how your loads work out with the Z-max H355 if you get a chance and try different loads.

Thanks again guys.
