Another newbie bullet question, but I have noticed a lot of manufacturers offer a bullet with a hollow point, then offer the exact same bullet with a plastic tip for a few more bucks (barnes, harvester, powerbelt).

If a projectile is traveling at the speed of these projectiles with at least 100 grains of powder behind them, is a little pointy plastic tip gonna do anything? Maybe its because I am new to muzzleloading but it seems like it just looks cool.
