18" Proof Research - 6mm ARC build and testing - factory and handloaded ammo
#28
That's what I understood. It's just that terms like "fatter" bullet imply to me that the 0.243 diameter is out of spec. I think what everyone is saying is, the 105 has a "stubbier" (my term) front-part, ie, ogive and forward. Traditional bullet tapers are "tangent" profile, while sleeker ones have "secant" or hybrid tan-secant style, longer tapers... again, if my old retired brain is tracking this ok. The 105 is probably the tangent style, whereas the 108 is secant style.
