FWIW.....Had good luck with this Cheerio's look-a-like powder when 231 gave me some case sensitivity issues in 45 Colt. Had it on hand for 30-30 under cast RNFP. Going to try it in 44 and 41 mag for light range loads. Any cowboy shooters use this stuf when you cross over to Bullseye or PPC.........Thanks.....2#
