All Hodgdon data listed in the Annual Manual runs 36,500CUP or less.

This will push 200gr. Hornady's out at between 2,450fps up to 2,630fps along with 250's at up to 2,328fps listed in this data.

Everyone who uses IMR or Hodgdon powders should buy this manual. I get one every year just to keep abreast of the new powders in these makes - along with reading the articles included concerning new releases & other points of interest.

Big Bore Rifle Ctgs. listed loads and pertinent data on the .348 using heavier than normal cast bullets up to 300gr. It was impressive.

Although the rim size increases bolt thrust at any pressure, the data listed by Hodgdon should be OK in an Enfield #3. Is it OK in a LeeSpeed? - I don't know.
