Okay. I’m curious. Can you elaborate on this? How do you fill it? Doesn’t it run out into the chamber?When you fill the tip with oil they open like a varmint bullet and penetrate like a solid.
Oil remained in the tip from their mfg process. When it was removed a while back, several users who have extensive history with the bullets noticed less than stellar results. There is/was a long thread on long range hunting forum about it.Okay. I’m curious. Can you elaborate on this? How do you fill it? Doesn’t it run out into the chamber?
Your post made it sound like you filled them with oil. Have you filled them with oil and experienced a difference in your use?
Less than Stellar results would mean to infer the bullets sucked in on game performance. Hammers are not known for poor on game performance anymore or less than any other bullet with respect to how they are designed to perform and the terminal results. It sounds like the oil is a silver bullet for a copper bullet that makes them almost infallible.
When I first started using hammer bullets they had residual cutting oil on the hollow points. The additional fluid in the hole opened the bullet much quicker into the animal. I was getting 2”+ entry holes in the ribs and inside vital s were more souped with fluid in them vs 1.5” entry and a more narrow cavity in the onside vitals with the bullet reaching full expansion and shed petals usually 5” in without the oil.Okay.

See my post above for a more detailed explanation. There are threads on long range hunting and hammertime forum discussing oil. There is debate among users at the amount of difference between oiled or unoiled, but I think it’s a meaningful difference and I choose to apply some fluid to the hollow point. But oiled or unoiled they don’t suck.Your post made it sound like you filled them with oil. Have you filled them with oil and experienced a difference in your use?

I did a search and didn't find a thread with respect to oil in the tips of hammers with the in-depth information you are referencing. Is it buried in some other thread?
Thanks for the detailed response. Thinking out loud here, it makes sense in my head. Fluid will apply the necessary expanding force more effectively than air. Like when a firecracker is dropped in a porcelain toilet full of water, it will crack the bowl. If the firecracker is dropped in a dry bowl, no damage. The same reason hydraulic fluid is used in machines instead of air.When I first started using hammer bullets they had residual cutting oil on the hollow points.

Now I just take my bottle of hoppes oil and put a drop or two on the hollow point before season. I’ve not noticed it running everywhere in my rifle.
Please don’t think they don’t work well dry. They are very lethal bullets but the oil gives them a little more pop if you will.
Typical entry with oil.

Exits average about the same actually. About 1.5” with petal distribution more widespread with oil and more centric without.
This data is observed over roughly 15 deer with the same bullet. (90 absolute hammer).
In the past that wasn’t necessarily true, there were revisions to the hollow point size along the way and more than one user got bullets from “bad batches of alloy”. Ideally all those issues are in the rear view but not gonna pretend some growing pains and lessons weren’t learned that affected the hunts of customers.Hammers are not known for poor on game performance anymore or less than any other bullet with respect to how they are designed to perform and the terminal results.
