Thread: 308 Subsonic powder alternative to Trailboss

Very hard to double charge if that's your procedure - easier if you are loading a tray of cases with powder at the same time.

The benefit of the faster powders is there is virtually no delay in lighting the entire powder charge and it doesn't really matter where the powder is in the case - no need for fillers. Downside is the pressure curve is fairly abrupt which is where the dangers of the double charge come in, but if your procedures are good on the bench you can prevent this issue from happening. Trailboss is designed to get around the loading density thing by being so bulky - but it's tending to be on the dirty side and a lot of people have gone away from it for this reason plus some rifles just don't play with it. Google 'The Load' with Red Dot powder, and you get quite a bit of info on using Red Dot with all sorts of pills in the .308 case.

I have both Red dot and AS30 their denstiny and burn rate are very similar, I am using up the AS30 first and then compare results with Red dot as I have more Red dot and don't want to waste it
doing load development, AS30 should be easier to source than Red dot at present.
