![]() ![]() 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. 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. 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. 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. grab a pill with one hand, take a primed empty case and drop a charge of powder in it and at the same time place the pill on top and seat it. Other powders aren’t so bulky so looking for alternatives really that are more readily available.Procedure when you're loading takes care of any issues with bulk or lack of it and the associated risk of double charging. The good thing about Trailboss is it is bulky. ![]() You may be surprised how quiet, accurate and hard hitting it can be. While you get your sub load sorted, try a load around 1200-1400fps. A published load for a Woodleigh lead bullet BTW.Īnyway. The big Grey cloud between muzzle and target turned out to be 215gn of too soft lead vaporizing at something around 2200fps over a 45gn charge of RL19. Starting out I wondered why my 303B was not registering any hits on a large piece of cardboard at around 35m. Higher velocity in cast is feasible with accuracy but tends to require a specific combo of lead hardness, gas check and bullet lube. Accuracy tends to deteriorate quickly after 1400fps. Generally 13gn in 30 cal and 303B will give you between 14fps. Its also useful with cast to consider 13gn as likely to be a max load. Below 10gn, any such powder, be sure projectile leaves your barrel. 10gn is a useful start point to work up or down from. Some other Shotgun powders are very close to AS30N, which is very close to Red Dot. ADI have published data for AS30N, a Shotgun/Pistol powder. For Cast bullets, Red Dot, Green Dot have been widely used in 30 cal. ![]()
