[QUOTE="John Klingenberg, post: 1703355, member: 107749"] You can't put enough trail boss in the case to make it cycle. H110 or 4227 is a good powder for the 300, 450 and 458 subs. As others stated a gas block may fix the issue but you'll likely have to drill the port anyway as youre already using a full open port with a standard gas block. Also with a carbine length gas you'll have to be in a precise niche to get subs and supers to work and itll never be totally reliable because as it gets dirty the parameters change. Also consider that you're getting back pressure from your can which is never the same every time. If it's not working or barely working then it'll never work with the can off. Asking for everything is tough. Cutting springs wont do it. Changing your buffer weights is a better less permanent option. [/QUOTE]
