Recommended Load(s) for 224 Valkyrie With 90 Gr Sierra HPBT

[loadedround]

I have a new HB AR15 with a 6.5 twist barrel. I am an experienced reloader and have several hundred Sierra 90 gr HPBT match bullets that I would like to use for 200+ yds. shooting. I would like any recommendations for using these bullets in my AR15. Basically powders and weights you've found to perform accurately. I haven't found too much reloading information online with this bullet weight. I appreciate any and all help guys!

I dont have specific data available at the moment but those powders max out around 26.5-27.5 grains with 88-90 grain bullets in my rifle. I think I have a Sierra pdf some where...
