Hey all I recently bought a 1lb jar of H335 to try out and I can not find any load data for the SS109 projectiles. On the Hodgdon website it only has one load data for the 62gr but it is not for the SS109. So if their is anyone using H335 powder and SS109 bullets what is your load data? I will be using these loads in a 14.5 barrel with Wolf Small Rifle Magnum primers. The cases are mostly Lake City 556 with PMC PSD and others if this matters at all. Any help is appreciated. Thanks.

Load for the bullet weight, not it's NATO designation or who made it. So use the 62 grain data. And make sure whatever range you use allows steel cored ammo.

Just use the data for the Sierra 63 grain.
Start at the start load and work up.
Your OAL may be different.
Seat to the cannelure on the bullet and whatever it is, it is.

Welcome to the world of reloading. Sometimes you just have to make do with the data that is out there, and it probably won't have the exact bullet you are using. What I usually do is use the powder charge they have listed for their 62gr bullet and then just adjust my OAL to what I think will work best for the bullet I'm using. With so many bullets on the market, it's impossible for companies to test them all, so just make do with the data that's available.

Hold on!
The data for H-335 does NOT say anything about 19.3 grains.
The start load is 22.5 grains H-335 for the 63 grain bullet.
It means, Thats what you should use to Start with!!
Also, if you intend to crimp in your seating die?
All your brass MUST be trimmed to the same length.
There is no getting around it if you want the ammo to chamber in an AR-15!!

I agree, the starting charge weight is just that, where you start. It's never a good idea to go below the recommended starting weight, it can be almost as bad as going over the max charge weight.
The bullet used in the 62gr load data on the Hodgdon site does not have the same profile as the bullet you're using. Like RC said, use the 63gr load data because the pullet profile is much closer to the one you are loading. The bullets you have probably range from 60gr to 64gr anyway. (weigh a bunch, you will see)
Use the 22.5gr load weight as your starting charge and work up until you find the most accurate load or until you hit the max.

Sorry for the delays. I am glad I read this when I did. I was about to go and try out these new loads. I used the 62gr data on the hodgdon website which stated 19.3gr of powder. I am going to tear down these loads and put more powder in them so they are up to par with the 63gr data. Thank you everybody I think you all helped save my hide.
UPDATE: Thank you to all who replied. I tore down the first couple of rounds and reloaded them with 23.9grs of h335 to test out. I did not test for accuracy just pressure signs and there was none. I am now going to test for accuracy. So again thanks for the help.
