Maker, 110 grain Expanding sub bullet for single shot/ bolt actions

Post by dellet » Sat Feb 11, 2017 11:51 pm

Starting to work with a new offering from Maker bullets, 110 grain expanding sub sonic bullet. This is one of the bullets that Paul got a fair amount of feedback and interest in to develop.

The first questions that always come up is how low of velocity and how far will it expand.


Image
Here is 700 fps into 10% ballistic gel. Bullet center to outer edge of petal is .400, total expansion is basically 3/4" at that speed.

Accuracy so far is reasonable. Weather has not been agreeable so chronograph time has not been possible past a few shots.

Image

Five at fifty yards, but were going super at 25 degrees

Image

Dropped down to 5 grains of Trail Boss and shot another five. Two cracked super so need to drop a little more powder.

Developing subs without a chronograph sucks, I think working the load from here will be pretty easy.

For small game, varmints and pest control these will work great. Using Trail Boss they are pellet gun quiet. Expect these to be showing up on their website soon.

I think this bullet has more potential for general hunting use than many realize. That thing expands to quarter size.
If you shoot something small and tasty, keep them toward the head or you'll lose some meat 8)
It should prove very lethal.

Back out today chronograph and a balmy 35 degrees two loads to test. Both shot at 50 yards.

Maker 110 Rex
LC converted 1.355"
Rem 7 1/2

4.0 Trail Boss

970 FPS This was first round
930
929
928
926

936 avg
44 ES
18 SD

Image
Vertical is about 1.4" horizontal is 1" outside to outside

4.5 gr Trail Boss

1040 fps
1042
1010
1018
1024

1026 Avg
32 ES
13 SD

Sadly I expected a little more difference in the groups. Basically three in the same hole, one a bullet width high and another high right. Basically 3/4" high and 1" wide outside to outside.

I think with a little work 1 1/4- 1 1/2 MOA out to 100 yards is a very realistic expectation. Those that want to tighten that up could probably squeak out a solid MOA load.

Something to consider is that I shot five rounds, went and cleaned the brass by hand, reloaded, came back and shot the next five rounds. The load is reasonably repeatable and forgiving at short distances..

The ten shot group is basically 1" tall and .8" wide. When you factor in the 100 fps velocity spread that group would tighten considerably.

It shows the importance of a chronograph to develop a sub sonic load.

I will probably call this good for now and try a different powder or two to see just how forgiving this bullet is.

Interesting bullet, for me specially for small varmints.
How deep in gelatin it starts to expand/how deep it was when expanded totally/how much was total penetration?
If we think small varmint body to be 6" thick under fur, does this expand if hit soft tissue?

Good questions that I have no real answer yet.

The bullet shown was not at full velocity, and traveled about 8.5 inches in the gel and was not fully expanded. My experience has been that there is not a good way to predict penetration. In gel a faster bullet may penatrate less because it opens farther sooner. Applying more brakes.

The other variable is target weight. With smaller animals it's easier to pick up and move the whole animal than to penatrate. It will take some real world testing to know exactly what will happen.

Expansion is started by hydraulic force so it could be possible to plug the hole with fur and cause problems.

Any good thoughts on controlled tests are welcome.

...not sure if it's a good one, but if you have some old pelts laying about you might be able to use them on the front face of your gel block or selected backing medium to test for the clogging potential?? Pelts may need to be "re-hydrated" to soften up the skin layer a bit....

I really enjoy the 90xtp's in my handi-rifle and have popped a couple rabbits with them. Did you by chance test to see if these fed with a magazine (manually cycling the action)?

They will feed in an AR.
