The Hevishot hulls being used right now should be Cheddite's, so far people have been using them but they aren't IMO the greatest hull to reload for 10 gauge, to many problems with brass expansion with them. Not much if any load data out there for them. The Winchester hulls as Baltz stated have less internal volume than Federals or Remington hulls, the BPD wads will work I have recipes for them or you can shorten other wads if you like. They are a very good hull to reload if you get things right, I have a 1 3/8 oz load that goes 1675 fps with them and does the job. The press, well P-W is a very good machine however you can get by with an MEC Sizemaster/Steelmaster and have very good reloads made up, plus they have the collet resizer which is a plus. BBB shot will work just fine, if you want bigger go to T's, F steel is waste of time and money not enough pellet count and believe me I tried to make it work. BBB will kill easily out to 60 yards with the right load. One you get ready just ask and we'll advise on powder and primers. And yes you will get 100% better performance and save some money to boot.
