Ar comp load data?

Hi all I need some help. I have ar comp powder, 55 grain drt frangible projectiles and CCI small rifle primers. We loaded it with 23.3 grains of ar comp powder. Have not shot it yet. We got nervous after looking at how long the bullet is compared to a 50 grain v max projectile. We set it at 2.25" oal.
Can anyone help and let me know if this is a safe load?
Thanks everyone.

No. Its a newer powder and couldn't find it in books. Its made by alliant powder and they have a load data page that we used but they don't have it for my specific projectile. We just used the load data for the sierra 55 grain projectile they suggest 25.6 so we reduced it to 23.3 grains. Link here. http://www.alliantpowder.com/reloade...6&bulletid=269

Data from Hornady's 9th ed. lists:

Ar-Comp powder min 22.7- max 24.8 w/55's

It does not list any bullets but Hornady's 5 different 55's

Many loads using AR-Comp powder for the .223 and Nato rds. it's worth the 25.00$ cost if you load odd powders and their bullets. 8208XBR, Power pro, CFE 223, AR-Comp
Data for 20 different powders.

Right that's my problem. And someone that frangible ammo is usually longer than other ammo I don't know for sure if this is true. But makes me nervous to even attempt to shoot it

Considering that the max load listed for 68gr bullets is that high and what you've loaded is basically the starting load for 52gr, you should be plenty fine.
The amount of bullet in the case makes a lot less difference in rifles than does the difference off the rifling.
