    13gr of Red Dot was considered the reduced load for cast lead with gas checks - google that one there's a heap of info out about it. Red Dot is a fast shotgun/pistol powder so reduced loads tend to not be susceptible to position sensitivity and don't require a filler - but at the other end don't like being loaded up as the pressure curve is steep (i.e. straight up). Google search a bit more about the options people have used on it and you might find a load that mirrors your barrel length, twist and projectile weight etc etc.

    The benefit of trail boss over red dot is it's bulk i.e a near full case is still likely close to subsonic. The shotgun and pistol powders don't have the bulk so need a little more care but the 13gr of red dot in a .308 case with around 165gr cast pills seems to be a fairly consistent performer. But do your research on it as I said especially if you want to adjust the speed you are achieving...

    Red Dot 700X 800X and AS30 are all nearly as bulky as Trail Boss and in the same burn range I have tried all of them at 8.0 grains in my .308 with the 151HP cast and they are safe
    I did not use any fillers and had no issues with ignition,

    Watching this thread intently - Having said those powders work fine, have you tried jacketed proj with these powders at all? Is leading a thing with using boolits in barrels needing scrubbing before returning to jacketed proj use? Hence my reluctance to use for subsonic use...
    Thanks RW !

    Ask your self this question do you get leading in your .22RF?
    The 151HP has a gas check which scrapes the bore clean they can handle 1800f, If there is any leading it will be from the copper fouling tearing up the bullet,
    All you need to do for cleaning is swab the barrel out with a good bore Solvent and a few patches just like a .22RF

    Always something to learn even at my age... Great example mate - consider me learned... Your experience and wisdom is much appreciated sir.
    Now to source the powders you mentions earlier for some testing...

    Lots of old shotgunners around Hamilton, so also keep your eye out for ICI Nobel 78 Shotgun Powder. I've used it a lot in place of Red Dot, AP70N etc. Lovely bulky powder. It is slightly faster than AS30N. Nobel never published data for Pistol loads with N78 so unlike the others mentioned in the thread, its not known for this usage. I used Red Dot load data to work up my loads in Pistol calibres with the start and max both a tad lower. Like all of them it can peak the pressure very quickly. I treat 13 gn in a 30 cal case (cf the original "The Load" of 13gn Red Dot), as very much a max load.

    Have fun.
    I know a lot but it seems less every day...
