dicehorn 38 Posted May 10, 2009 Report Share Posted May 10, 2009 I'm new at reloading rifle cartridges.what size primer for .243win. I'm using 107 sierra bthp for whitetail and not sure about powder. Large Rifle primers. I am experimenting with Federal 210M and CCI primers. What is the twist rate in your rifle? Asking because many people with a twist rate 12 and over have difficulty in getting heavy bullets to shoot through such a slow twist rate as 12:1 and 13:1 In my experience slow twist rifles favour the lighter bullet heads. If your twist rate is something like 10:1 then you should have no problem with the 107 gr heads H414 is a popular powder for the .243 Peter Quote Link to post
SNAP SHOT 194 Posted May 10, 2009 Report Share Posted May 10, 2009 most common teists in the .243 are 1 in 10 or 1 in 9 1/8, The .243 shooting 107g bullets will need a 1 in 8 twist to stabilize them, good powders to try are vit n140, vit n 160, varget, and imr 4831, and reloader 15 or 19 depending on bullet weight.... varget is a very good powder in the .243, Snap.
