  Well can't help to much. My favoriye Varmint load for 243 is:
  
  70g Nosler BT
  Win LR Primer
  41.5g Varget
  
  It is a tack driving load out of my Rem 700.

  Published loads from Sierra lists 37 to 39 gr. of RE-15 for the 70 gr BK bullet or 41 to 44 gr. of IMR-4350.

  My pet load is:
  
  85 Gr HPBT Sierra pills
  37.3 Gr of IMR 4895
  CCI LR primers
  
  with mostly Remington brass (but ill take what I can get for brass).
  
  1:10" twist Ruger M77 SS 22" synthetic
  Simmons 3x9x42 silver (cheap scope but does the trick and is clear). just a beaut!!!
  
  Set up a group of 3 at .90 MOA at 100 yds. Very effective varmint and field deer load
  
  .02

  You have three good powders for the 243!
  
  For accuracy testing I check the minimum and maximum recommended loads in a reloading manual, I load three rounds of the minimum load, three rounds at 1 gr less than maximum load, and I take the medium average of the low and high recommended grains and load three rounds!
  I test on paper at 80 to 100 yards with a cool barrel and pick the powder that the GUN seems to prefer for best accuracy and then start testing in 1/2 grain increments for the 243! You did not state your type gun, Rem, Win, etc or the barrel twist, but most often the 243's prefer a 85 grain bullet for best accuracy, but then again you never know! Testing is the fun part for accuracy when fine tuning a load, but not so much fun if the gun is shooting 3 inch or larger groups or the FIRST SHOT ONLY cold barrel shot is a BAD FLYER!
