[QUOTE="elkaholic, post: 694954, member: 13833"] That's encouraging with the OTM's. One thing about a large, heavy bullet, that inertia will help expansion over a lighter bullet with the same type of jacket. The SMK is the WORST bullet I've tested as far as expansion in a target style bullet. It's not because the jacket is thicker, it is because of the tangent ogive vs a secant; or at least that is what I believe. The angle of entry against the nose has a lot to do with whether it opens or not. The sierra jacket is actually a thou or two thinner than a J4. If you build that S.I., I may donate some SXR's for testing:D......Rich [/QUOTE]
