[QUOTE="QuietTexan, post: 3051091, member: 116181"] What all powders do you have to work with? Trail Boss is safe to start with if you can find any, just be 1000% sure you don't compress it at all. H110, IMR 4727, AA1680 and Lil'Gun are common powders for subsonics. H4895 is know to work well at very low chage densities also. In terms of hard load data, google-fu says 11.9gn of CFE BLK behind a 245gn lead cast bullet, 10.7gn H110 behind a 220gn Berrys plated bullet. QL predicts starting around 15.0gn of H110 and working down, should be ~80% fill so you should be able to hear the powder move while shaking the case. If you can't charge lower weights until you can. You should hit subsonic at ~13gn. [/QUOTE]
