This chambering came about when I mis-cut a 22-250 AI chamber on a 26" 9 twist barrel I had. It was a lemons to lemon-aid undertaking so to say.
I had a bag of 70 gr. RDF seconds that I decided to use for load development, as I was unable to find an accurate load for them in my 223 and 224...

"What this President did to those who were our allies in Afghanistan is morally indefensible and criminal. I have no doubt that good people in State and in Defense are embarrassed for the diminished status of America. Good for Catherine for making her feelings clear."

My experience with 130 gr. bullets in a 270, the powder sweet spot for performance are powders are: H4350, RL-17, RL-19.
My 270 has a 24" barrel and all three of these powders deliver accuracy in my rifle and with higher velocity than H4831 generates.
If you're not getting the accuracy you are...
RL-17 makes my 270 rock with 130 gr. bullets.
You have plenty of pressure headroom to increase the amount of RL-17 and perhaps going forward you will find the magic point of power and accuracy.
I'm seeing H4350 locally for far less than that. I'm wondering if the manufacturers are having retailers "bid" on available powder and some pay elevated prices just to have something on the shelf to sell.
All this high tech....
My old school barrel bobed and suppressed 581 Remington toys with MOA accuracy off the bench at 100 yards with Norma TAC 22 subsonic on a calm day and even better with R50. Not saying this is the be all 22 rimfire, but that old rifle can stack them into a tight group...
GRT => Gordon's Reloading Tool is like Quickload, but is free and not as comprehensive.
My 416 Taylor sports a 24" barrel, but 83.6 gr of RL-17 pushing a 350 Speer GS delivers 2622 fps and 5344 fpe in my rifle.
It's a max load, and you really don't need to load it that hard to get performance in...
