In relation to wad pressure, I am using a winchester 1 1/8 oz plastic wad with the petals cut off over the powder and a 1/2 felt wad on top of that which gives me the correct height in the 2 3/4 case for the roll crimp. I am using an old MEC to give me wad pressure. I have ordered a Chronograph to help with the load development.
It is very hard to judge when you have reached a maximum load as there are no pressure signs like you get in a rifle, so I am treading very careful. The load given in Wrights Book on shooting doubles if it is 3 tons = 6,600 pound taking into account that the Marlin is fully rifled, should give me a safety margin if I use that load.

My Paradox mould will be here by the end of the month. .729 and a nominal weight of 735 grains. It is a hollow nose. This should not be to much different with the one I have borrowed.

Since ADI has been producing powder for the home market, it has been difficult to get any other brand. I can Alliance powders, but IMR, Hodgdon winchester are a thing of the past now out here.

In your opinion, what would be a safe achievable velocity for the RB in the Marlin (Fully rifled barrel) taking into account that it will be used on pigs, deer and competition as a bore gun. I was going to look at 1300fps, but would be interested in you view.
