I would agree with that with logic I don't know bout technicality but you would think oil exiting would cause issues too with stabilization. What caliber were you shooting with those hammers? In really just going for a 700 and under elk gun so hopefully these will work out.
Awesome thanks for a seconding on that. Have you noticed any I'll effects from that? Guess I'll just take a can of air or something to them from now on out! Thanks!
You're seeing the moisture condensing along the path of the bullet. It happens with all high power rounds. In sniper training, the sniper and the spotter are trained to watch for the vapor trail created by the bullet so they can judge bullet impact at distance. Its nothing wrong with your rifle or your round. You ought to see the vapor trails from an M2HB cal .50 going down range at 800 meters. With a spotting scope, you can see the trails pass through the target.
Yes, you are exactly correct about being slightly out of focus causing the trail to be more visible. That's what we were taught when watching for them. They can be seen as long as the bullet is creating a supersonic shockwave, so as long as the projectile is going faster than sound, you get a vapor trail. In high crosswinds it is very hard to observe, and in really dry environments the trail is less visible, but a good spotter can trace it to the target. As to oil in the hollow point, I think you'd need an awfully lot for it to be visible, and the amount in one of the Hammer bullets wouldn't even be a full drop. It would be vaporized in about 10 feet, I think. And since its in the front of the bullet, I think it wouldn't make any difference, since it would be held there by momentum and pressure. That's why the Military puts tracer mixes in the back of a projectile instead of in the front.
