Just measured the COAL with a 500 grain roundnose FMJ in a 2.5" case on the cannelure. It was 3.33". So the .450 Howell will fit ok in a Ruger MkII Hawkeye action using 500 grain softnose roundnoses which are slightly shorter or 500 grain FMJ's. Boyds make a nice classic laminated stock with cheekpiece that weighs around 2.8 lbs which would be ideal to add some weight to the rear to balance a 21" .458 barrel at roughly 9 3/4 pounds with a chrome-moly Ruger action including scope. Should get 2150 fps out of a 21" barrel using Varget. I would put an extended magazine well on so as to hold 4 rounds in the magazine and use a stainless barrel Cerakoted a medium to dark gray so scratches don't stand out too much.
