u can do any of those..... here is a coupla guys that may better suit ur question tho...
id try 110g of 2f with some good heavy steel wads in that gun to start. and maybe go up from there...... remember its not a magnum, so stick to 1oz or 1 1/8oz of shot with steel so u get the speed. order up some sam-1 wads from here....

they are by far the cheapest, and shipping is cheap too.
if u can get some 1f black it would be better for ur speed. start with 125 or 130g. or even better would be 20g of 3f or 4f and 100g 1f on top of that. i still use the nitro card wads under the shotcup to help keep the plastic out of the barrel in my .62 smoothy, and it will lessen the pressure some. and the lubed cushion wad between the o/p card and plastic wad will soften the fouling ull get with the 1f or 2f.
make sure to cut ur wads to the length of the shot inside so it doesnt rattle around and knock the o/s card out. and if u dont have a chronograph, u should borrow one or try to find someone who has one to make sure ur pushin that steel fast enuf. u could use hevi-shot, but its so expensive, u wont want to shoot the gun.
