Big Bore Shoot with Steelhead
« on: December 29, 2018, 07:01:17 PM »
Made my way to Steelhead’s family farm this morning. It was crisp but clear and sunny when I got there. Warmed up in no time at all and perfect.

Before heading to the farm I gathered up all my stuff and filled two DAQ rifles and one DAQ pistol,  the 909s and my Sumatra. Filled the big tank to 4500psi and the small tank to 4000 psi. I feared blowing another burst disk so avoided taking it to 4500.

Small Ninja tank has been a pain and to top it off it was regulated to about 2900psi. I wanted more so I contacted Ninja and they sent me a purple and a gold shim. At first I tried both which made for  a regulated 4,000 psi which was too high. So I took out the gold shim leaving the purple one in place.  That did the trick at about 3200 psi. It’s enough to give any of the DAQs 3 shots and I can reduce fill to any airgun needing less pressure. All three DAQs appear to actually prefer higher pressures, up to 3700psi, but good grief I can empty a tank lickityspit.

I got a Huma regulator for the big tank and today I got to use it finally. It’s set to about 3250psi which is a reasonable compromise.

The goal today was to:
1. Have fun
2. Use a tethered and regulated air supply
4. Try three new bullets I’ve poured this week, and avoid going nuts.
5. Try to make groups at 30, 50 and 100 yards. Then and only then switch bullets.
6. Test the .575 pellets that Ronald sent me from Holland.

To be continued...(got interrupted)

Continued:

I started out with the .575 DAQ Short Rifle and decided to give the new .575 EPP-UG's a go. They are 332 grains on average, and they are as dropped from the mold. Most of them are at .575 - .576, give or take. I did a better job than usual casting these and they came out all shiny with good fill out and few defects.

First target was a 5 gallon bucket stuffed with shredded tire rubber. Stick on Target goes on the lid of the bucket and I turn it sideways so as to have a longer bit of rubber the bullets have to go through.  I thought that it made a good big bore backstop, but boy was I wrong.  I think it was the second or third shot that made it all the way trough and out the backside. Whoops. I need to revise my thinking on that.

I sighted in, adjusted the scope until I was within a half inch of where I pointed. The first group after sighting in,  I ran over the crony. Three shots:

.575 EPP-UG - 332grains - tethered at 3250psi
1. 709.3 FPS
2. 715.5 FPS
3. 702.6 FPS

Average 708 FPS for an average FPE of 369.62.  After this my record keeping (as usual) gets, ummm shall we say spotty? 

I was making genuine groups. First 3 shot groups and finally 5 shot groups that were mostly touching, yes, I know at 30 yards. Then to 50 yards, and certainly smacking steel at 100 and 150 yards.  That's a big assed chunk of lead flying in a most a rainbow sort of trajectory. I have determined that this particular rifle, and it's sibling .58 pistol are 25 - 75 yard hunting guns. That's what they are designed for and that's where they do the best.  Tethered gave me time to prove to myself that the DAQ .58 Short Rifle is capable of groups, in spite of the serious flinch I still have. I am very happy with the results of Bob's Design, and the performance.  Huzzah!

Next up were the .58 pellets that Ronald sent me. Well, I made a couple of mistakes here. Damnit. Number one I did not carefully measure them and then size them. They are too large a diameter for the DAQ. I have a .575 sizer and I do wish I'd used it. Result: first pellet stuck in the breech. Add to this foible, the fact that they are a hollow base, and the bolt has a pin that ends up in the hollow base. So the pellet and other bullets with hollow bases like Minie Balls do not get pushed in front of the transfer port. That's no good. I need to make up a tool to push such bullets all the way in. Or beg Dennis to make me a modified bolt that can accommodate hollow base bullets. Or just skip the idea of the big ass pellets and Minie Balls.

Number two mistake was not bringing the wooden dowels I use to dislodge a stuck bullet. Crap. So the .58 DAQ Short Rifle was out of commission.

Sorry Ronald, I will figure something out, and do proper testing of the pellets. I'm obsessed, and no roadblock will remain in place for long.

When I got home I slid in the wooden dowel and one tiny little tap dislodged the pellet. I then shoved in a .575 EPP-UG and I see that the base of the bullet is right on the edge of the transfer port. Hmmm, I look at the  DAQ .458 Outlaw and shove in a bullet and it has a good 1/8" clearance between the bullet base and transfer port. I am wondering if there is an accepted optimal distance? Will call Dennis and bug him some more.

So with the .58 DAQ Outlaw Short Rifle put away for the day, I thought ok it's time for the .458 DAQ Outlaw. Decided the .454 Maxi Ball was the ammo to test. Now I had my doubts about this bullet, but Ronald said to give it a go, and boy am I glad I did. I brought about 30 of these with me, and went home with zero. I need to cast up some more, and now I'm thinking I need a 4-6 slot bullet mold instead of the single. It bloody takes forever to cast any good number of bullets.

Again, I used the 30 yard bucket to find paper, and get reasonably close to where I was pointing. Actually first I had to remove the scope from the rifle so I could tighten the barrel screw down to the airtube/hammer part of the rifle, as I noticed it was a bit wobbly. Note to DAQ owners. You should check all the connects after each shoot as stuff loosens up.  Got it all back together and the rifle lost it's previous sighting in.  It shot about 7" to the right and another 6" high. Worked on getting it to shoot to where I pointed it, and then tried for some 5 shot groups. All were touching. Oh this is awesome I thought. Then I worked on 60yards, and the rifle maintained close groups. They opened up a little at 100yards, but they all fell within a 5" kill zone.  I say that hoping that one day we are able to hunt blacktail deer, and piggies in California with airguns.

I am very surprised the Maxi Balls did so well at what I thought was a very undersized bullet. That is very interesting.

.454 Maxi Balls - 230grain - tethered at 3250psi
1. 806.3 FPS
2. 812.5 FPS
3. 809 FPS
4. 822.6 FPS
5. 822 FPS

Average 814 FPS for 338.48 FPE

When I was sighting in the rifle I'd forgotten that I had filled the rifle to 3600 psi with the YongHeng.  So the first numbers were:

.454 Maxi Balls - 230grain - NOT TETHERED at 3600psi +-
1. 901.2
2. 901.2
3. 911.1
4. 901.1

Average 903.65 for an FPE of 417.14 FPE. That's more like it.

I had to go back several times on chrony to double check the numbers. It's crazy numbers and I will revisit this again next airgun shoot. And I will see if I can't get a second big tank so I can run at 3600-3700 for this rifle. It loves that pressure and the sound of these Maxi Balls flying through the air is crazy.

I shot up the rest of the Maxi Balls and then tried the Round Nose bullets I cast from the On Sale 6 up mold from Lee.

Shot up a bunch of round balls and .457 EPP-UG in the 909s since it likes 3,000 psi just fine. I tethered up the small tank and let lead fly. It was actually more fun to shoot with open sights, and not getting so beat up like the DAQS do to me, and I was hitting steel at will at 50 yards and 100 yards no sweat.  I think it would be a perfect small pig or small deer gun.  No muss, no fuss, and simple. I can squeeze out three-five shots.

We started packing up, and I remembered the DAQ .58 Pistol was filled up and I pulled it out and shot once and handed it over to Kevin. He got two more shots out of it, and said, here's your tree stand gun. And I thought indeed.  Great for hunting in tight woods and short distances. Dennis advertised it as a beer can gun for bouncing beer cans in the backyard. Well, when you fill it to 3500-3700psi this is no mild mannered airgun. I have no doubt it will put down a sizable deer or pig at 50yards. It is just plain fun.

Kevin is as always a great guy to go shooting with. And I sure to love it out there in the open space. It was a perfect day. Thanks Kevin!

P.S. Damn you for putting the idea of a .257 Texan in my head. Gotta  find something to sell so as to pay for a new Texan. Maybe. GAH!

6. Test the .575 pellets that Ronald sent me from Holland.

Geez! You lucked out like I did! Someone sent me some Ghost Pepper sauce, that's to die for. Imagine!?

Nope. See the continued bit above. 1. I’ve now resized the pellets but still have the issue of hollow base. Bolt was designed for flat based bullets. Bah

I hope the jelly didn’t bite as much as the .58 DAQs bite! Well actually I enjoy a spicy wallop but that’s me. Sent Kevin off yesterday with a jar. Will be interesting to hear how folks at a gathering found how hot the jelly to be.

Ok sorry to hear.
We convert the rifles to hollow probe.
Far more efficient and youre be able to shoot  all ammo.

A probe is simple to build.

No worries. I will figure out something. If I had a lathe and mill, no doubt I’d figure it myself. But, I don’t and don’t need yet another distraction.

As Steve said, a great shooting day. It was good to see his progress on tethered/regulated shooting. For paper punching it's the only way for big bores. I've found that my Texan does not like round nose bullets (in any grain)  Flat nose absolutely takes the cake. For best performance it's either the 118 cast flat nose or the 127 gr. 309 NSA with a close second to the 154 gr. SP cast. Those performed far better than the others. This has been the case for a while, but I put a lot of different stuff down range and what I found was that 118 gr. round nose, 134 gr. round nose, and especially 79 gr. don't shoot well at all. Anything with a round nose shot at least 1.5' to the right at 100 yards. The lighter the bullet, the more exaggerated this became. The afore mentioned slugs that worked well did not deviate on the windage.

As usual I forgot something small...my fill probe for the FX Streamline. Oh well...just had to shoot more cans and flotsam with the Texan!

Great day as always, Steve. Let's do it again sooner than later.
