You might give H4895 a try
I'll have to kick-in also; H380 has always been my top choice for .22-250's. Yes, it's a bit dirty. Try std & mag primers to refine accuracy. H380 flows through a powder measure super! Due to the normal 1-14 twist, keep pointed bullets weights under 60gr. If you must shoot heavier bullets 63gr Sierra semi-pointed or 70gr Speers.
I've also had some pretty good luck with H4895 & it burns clean.
