Request for Data From Reloading Manual

[Phil3]

I am newish to reloading and want to reload 223 Remington with Hodgdon H-322 powder using 52 and 53 grain Sierra Matchking bullets as well as 52 grain Hornanday A-Max. For an AR-15 with 1:9 twist barrel. My Sierra manual and Hodgdon on-line date give me widely disparate load values. 23.1 to 25.2 for an AR-15 in the Sierra manual and 21.5 - 23.5 in the Hodgdon info. It would help to know what any other manuals say. My Lee and Lyman manual have no info for this powder. If you have info, please let me specificied OAL, bullet used, and case length too if published.

Thank you.

Phil

My Hornady 8th & 9th Edition is showing;

22.2gr to 25.0gr
w/ 52gr A-Max, 52gr BTHP, 53gr V-Max and 53gr HP.

That's .223 Remington w/ H-322.

Not seeing anything in my other manuals for those loads (bullet + powder combination).

I generally try to use the powder manufactures data if the projectiles I am using are listed on their website.

Also try to take other information into consideration when looking at recipes.

Hodgdons website shows the 21.5 to 23.5 range for a 1:12 twist 24” barrel with Winchester SR primers.

My Speer #14 manual shows 22.5 -24.5 for one of their 52gr .224 bullets using H322 & CCI #400
