Is this the case with all tipped bullets (Ballistic Tips, SST, Accubond, TTSX, and such)? I understanding (probably due to sales pitches) is the tip promotes rapid expansion and increases BC.
And I'm not being facetious, I'm sincerely asking you as more an SME than I.
Yes that is my opinion. The tip increases bc on bullets that would otherwise have very large meplats. In a lead core bullet the lead will act somewhat like a fluid in the nose of the bullet on impact but to really work as needed the fluids of the target need to get into the bullet to cause good expansion. For this to happen the tip must get pushed straight back and cause the hole to get larger than the tip to allow fluids into the bullet. Or snap off allowing the shank of the tip to push into the hole with the fluids behind that causing the expansion. The tips also allow swaged bullets to have a more uniform point than without the tip. I think they work well for the flight ballistics but are a compromise at best for terminal ballistics. If you removed the tip from a tipped bullet the flight characteristics would suffer greatly but terminal performance would be enhanced.
Our goal of high bc non tipped bullets will move forward. We will always error on the side of terminal performance rather than bc on a hunting bullet. We are close.
