Hammer 22 Creedmoor Testing

Out of these which will you choose to better tune?
None. This kind of wind, I'm dealing with at least a tenth mil of AJ and a couple tenths of a mil of wind. I refuse to tune in conditions like that. There's nothing to be learned other than "hey, is this bullet/powder combo even worth looking at?" Clearly it is worth looking at. ;)

Introducing the next Primal Finish in-house camo - Bedrock Badlands!

This is the first pdog I've shot with a Hammer bullet. Hit him center with a 70gr Hamer Hunter at about 200yds. He flew 10ft in the air, and landed in a pile loosely held together by fur. I expected these things to just pass right through. It was kind of shocking actually.

Velocity on the 70's?
3605 FPS ...and that's just 41.5gr of H4350. These things are moving out.

I like those crono numbers, got some 63 grain hammers enroute to see how they do!
 
So I made an interesting discovery yesterday. The 70gr HH's had their tips filled with varying amounts of some kind of oil. It was foreseeable to me that this non-uniform amount of oil in the tip, as well as along the exterior of the bullets, could be causing the variance I've seen. As I haven't been able to get significantly better than 1/2 MOA, consistently.
So, I used a tight fitting hex wrench and shoved it in the tip, to force the oil out, then wiped it on a paper towel. Then I put the bullets in a fresh paper towel and tried to clean the oil off the bulk of the bullets the best I could. I then re-shot a basic seating depth test this morning.

As you can see, there wasn't an insignificant amount of oil in these bullets... as there isn't very many bullets and that paper towel got pretty wet.

The top row was .010" (ten thousandths) jump increments. Seemed like it really liked about 10-20 thousandths off the lands. Then hit a scatter node as the POI shifted downward, then tightened back up at the lower POI. This is what a real seating depth test should look like. Very clear conclusions to be drawn... with the first two groups being dead even on the horizontal axis like that.

I seated 9 rounds right there, and then the wind came up to about 15-20mph from 3:00... and you can see the groups shifted up and left, as I would expect. The wind and some AJ... perfectly lines up with calculation. Not much else to learn when it starts blowing like that, so I'll continue confirmation a different day. I'm going to have a conversation with Hammer Bullets about the oil when they get back from Africa. I don't have enough experience with these bullets to know if this is normal or not. Getting the oil out of there and off the exterior DEFINITELY tightened things up. One super tiny group there in the wind, and a couple others in the seating depth test row that were pretty nice too. With any luck, a primer seating depth test is all that will be needed to pull that last bullet hole of vertical out of it. This has me pretty optimistic.

I've already designed a centrifugal force tool that I'll be using to solve the oil issue if this is standard for these bullets.

This thread is rather entertaining. Thanks for the updates and making me want a 22 Creed. Just what I need to add to my other Creedmoors lol.

Any hammer I've shot had I assumed cutting fluid in them. I was thinking of tumbling in shredded paper. Never got to it tho.
 
The oil in the hollowpoint is a common thing. They used to blow it out of there when they were done but they do not do that anymore. I stick a thick paper clip end in there to push the oil out and wipe it off with a towel as you did. They say it doesn't affect anything but I cannot for any reason see how it doesn't affect flight.

It's also annoying if you have an inertia bullet puller because the oil comes out and then when the bullet comes unseated, the powder gets the oil all in it, thus ruining your powder in each case.
