Considering weight and shape to a revolver 6" barrel. What is best?

Any of the Keith SWC design molds work well. I use a Lyman 429421 that cast about 245-250 grain bullets. The RCBS or Saeco versions would probably work well, too.

I don't know that there is any one best mold for the 44 spec. I've used Lyman's 250 grain SWC with good results, NEI's 230 grain SWC with good results, RCBS's 240-250 grain SEC with equal results. All of the above weights are what my bullets weighted rather then what the maker said the bullets would weight.
I have a full wad cutter 225 grain gas checked made by an out of business maker that's fun to use. This bullet is pure hell on groundhogs up close.
I've found that my bullets should be .430 in diameter for best results. I always opt for four cavity molds since I'm lazy and want to get the casting done and get to the shooting.

Don't shoot the .44 spec but do shoot a lot of light loads in my .44 mag and use the Lyman 429421 cast with WW+ 1% tin. Comes out at 252 gr with LBT soft blue lube. ( LBT soft blue is the best I have found). I use 6.0 gr of Red Dot and it is accurate and comfortable to shoot. Meas your cylinder throats and size your bullets about .0005 under that meas. If you don't have access to tin straight WW will work fine.

I use the Lyman cowboy action shooting bullet. In 44 it weighs 240 gr. and is more of an LBT type shape. It is surprisingly accurate out of the S&W 696 I shoot.
