I have some 69 gr sierra BTHP match king bullets I am going to seat tomororw. If I understand correctly, max COAL for .223 is 2.260". The Sierra manual shows COAL for this bullet to be that max of 2.260". Most other bullets I see are recommended shorter COAL. Don't I want to back off on the 2.260" max so I have some room for error and am not touching the riflings? Thanks.
