steve_b_wales Posted October 9, 2011 Report Share Posted October 9, 2011 A .243 moderator, specifically made for that caliber, should have a minimum hole diameter of 6mm. A .223 bullet is slightly smaller (5.56mm) so in theory, should exit the hole without touching the sides. Quote Link to comment Share on other sites More sharing options...
kent Posted October 9, 2011 Report Share Posted October 9, 2011 Its fairly std practice to use up to a 6mm clearance baffle on .22 cf.mods and .30 cal on anything over and up to. If you look at the very long established moderator manufacturers they dont do tight calibre specific baffles. Baffles remember are meant to deflect and cool the gasses not give the bullet a squeeze! Any slight mis alighnment of the thread to bore or even if the moderator works a tad loose could create contact on tight baffles. Remember .223 is 5.56mm .243 is 6mm not that different in fairness Quote Link to comment Share on other sites More sharing options...
