280Ackley and IMR 7827ssc

[Cageyc]

Does anyone here know how this powder works in the AI? All that I see is that it’s not too bad but not the most accurate. It seems the preferred is the 4831sc.
All comments are appreciated.
Thanks.

I’m running IMR 4831 with 150’s in my 280AI.

7828 should or could be a good fit with 160gr and heavier bullets.

If lighter than 160’s I’d be thinking you’d get a bit of inefficiency with 7828 as it’s a pretty slow burn rate.
