I have always encouraged everyone I have talked with to do their own bullet testing. Bullet testing as with many other comparisons can be swayed to effect the outcome. If you know the gun or bullet maker personally and are friends with them, if you benefit financially from one bullet or gun doing better in the test, or if you "push" a certain bullet or gun, then one is supplied with them free or at a discounted price I just am very skeptical of the results. Point.....comparing round nose bullets to flat nosed bullets of the same configuration. The results will be swayed and not really accurate. In this Linebaugh Siminar, if the 416 Rigby was shooting a 400 gr Barnes Banded Solid or a Woodleigh Hydrostatically Stabilized Solid, the results would be very different and everyone involved already knows this. A test would need to be conducted by impartial parties without an agenda to push that benefits them financially.
