I'm looking for load data for a 10" 45/70 barrel. I have some IMR 4198 and Sierra .458 300gr FN HP's

Thanks drawn

  Sorry, I only have a Speer and Hornady Manual. I have seen a Load book that is strictly for the TC Contender. Maybe someone else on the forum will know about it.

  Hang in there, drawn... When I get back to my reloading bench tonite I'll post what I can find. The Lyman guide has a section for Contender's & I have the Contender-specific reprinted manual as well.
  
  Here's what I found:
  
  Loadbook's 1997 (p. 375) reprint from Sierra's (and Sierra's 50th) gives handgun loads for 300 grain JHP IMR4198 - 38.8 gn start (1450fps) to maximum 43.2 gn (1650), H4198 - 39.4 gr / 43.4 gr (same velocities), COL 2.535"
  
  As always, start with the minimum load provided & work up as needed, keeping an eye out for overpressure signs.

  My Lyman 47th editions shows the following for a 300 gr. JHP,for IMR 4198 powder.
  sugg. starting grains 31.0 for 1008 fps in a 10" bbl.
  max. suggested load 36.0 gr for 1297fps in a 10" bbl.
  This is from the Contender section of the manual.
  shows oal of 2.550
  As alwyays,use caution on the top-end loads,although this is not top-end for the calibe,but the gun itself.
  Not responsible for accuracy of this post,or safety of this load.I just posted what the book said.(and of course triple-checked my input).
  One thing I learned with my t/c in 45-70 was the true meaning of download.:)
