i'am gonna load some 2 3/4 shells 1 1/4 shot and 3 3/4 dram of powder. what kind of powder do i need to use to make it as powerful as i can get. this is what i was told i needed to use. but this is all new to me so if i'am wrong let me know. i plan to use #4 shot. it's to shoot crows that fly high.

The type and amount of powder needed will depend on the gauge of the gun, brand of hull being reloaded, and type of wad used. You need to locate a source of load tables and find recipes that match the components you have. Then the powder choice will be obvious.

we would need a lot more info- what brand/ type hull- what wad you are using to even start- go to Hodgdens or Alliants web site and check their data

It sounds like you are just getting started at this. I highly recomend you pick up a copy of Lyman's 5th Edition Shotgun Shell Reloading book and read the How to section. It will also be filled with the loading data you are asking about. Once you have given that a good read and have checked out the data I think you'll be well on your way. You will also want to pick up a good scale to verify your drops and keep things safe. Of course if you have any questions after reading Lyman's 5th there are good people here that can help with most any question.

I would highly recommend reconsidering the 3 3/4 dram load, a lower velocity will generally pattern better and will subject you to MUCH less recoil. I'd look very closely at duplicating the "pigeon" loads from the old days of live pigeon shoots, they were generally 1 1/4 oz of hard/magnum #6 shot at about 1250 fps. Very good loads, patterned well and hold there patterns at long range.
