Re: Favorite powder for .243
If you have a standard 10 twist barrel, you then have to settle on a bullet weight. depending on your barrel length you may want to look at a little slower burning powder. However, if you have a standard 22-24 inch barrel, two good all around powders are H414 or Varget. Both cover most of the bases pretty good and there is plenty of load data out there. Once you find something that works well for ya, stock up! Good luck!
