My Daystate Delta Wolf .30 experience at 55 & 115, a few possible questions ??

So first day at the range with the 30 cal delta wolf. A bit of mixed results some good and some ok.

First off at 55 yards the 30 cal using FX 44grn pellets shooting around 920 fps printed a 1 hole group of 7 to 8 pellets. This is the tightest group I have ever shot of a group with a new air rifle. 

I proceed to adjust the gun for some reason down to 880 fps more of a standard velocity and increase shot count. The groups had a tendency to break out more left to right or the wind messed with it a bit. Groups were still good at 55 yards pushing about 880. 

I went out to 115 yards and mixed results some where ok groups others were bad and probably the wind/me not shooting that accurate. 

My Take aways for the rifle. 

1. The gun feels and shoots well, Shot count sucks thou. Probably only 30 shots per a fill and the gun flashes that pressure is too low to push slugs fast after about 1 or 2 clips which is only 16 shots or so ???? 

2. I did try FX slugs 44.5 and were mixed results. I was only pushing them about 900 to 915 and at a 100 yards seem less accurate than the fx pellets. I do understand what slugs have for advantages but at 115 yards the pellets were doing really well. 

3. More testing but am a bit confused with mixed emotions on to keep trying to use slugs in this rifle. First is shot count per fill which is really bugging me. If I have to really increase the power to say 960 or more that will really kill the shot count per a fill even more than what it is performing now. 

Second if pellets are just as accurate or more accurate from 1 to 100 yards, do I give that up to push out to 150 yards with slugs or just learn more wind doping with pellets ??

4. Might try some other caliber to see if I can still get reach and accuracy out to 100 Plus yards with out filling up the tank every 3rd clip. 

5. I did not see an option for programming the rifle to go over 1000 fps, it looked maxed out at like 980 fps or around there ? Is this not possible in this gun say for lighter pellets or calibers going faster than 1000fps. Is this limited by the onboard chrono ?



Anybody with Delta wolf experience like to give me your impressions ?

I upped my bottle to 580, as well as ordered a 700cc bottle. You have to remember that this is still considered new. More fps does not always equate to accuracy. Also note that this is also a 600mm barrel even though it looks longer. The chronograph takes probably 100mm.

Health wow, ok so can you give me a link to order the 700mm tank. Also, is that the standard barrel length of 600mm?

Also, is 980 the max speed ? I just got done re-watching a guy from Patagonian on youtube that is shooting pellets at 925 with just awsome groups and jsb 45 grn. 

I will probably up back the pellet speed to 925 seem to really shine at that speed. Might try the fx slugs again but the gun just seem to have a knack at that 920 to 930 fps for pellets and also confirmed by a few youtubers. I normally go about 850 to 900 for pellets but if it works just use it. 

Thanks for any additional info. I am really digging the integrated chrono on this gun. Makes constant feedback so nice....

I'm shooting a .30 Impact, so can't comment on the gun, but can offer feedback on projectiles. JSB 44.75 is an amazing pellet. They will do 1MOA at 100yds, but only in dead calm conditions. Typical real world conditions with light breeze I get 2-3MOA at 100yards. You can really see the horizontal dispersion kick in. This is 10 shot groups, not quickly done 3 or 5 shot groups. Pellets are super frustrating to shoot at 100yds+ because your wind dope is jumping all over the place. You may shoot 3 or 4 shots into 1MOA, then a small change in the wind causes a huge shift in POI. With slugs that shoot 1MOA, they hold a lot closer to 1MOA even with a breeze. I tried the pellets at 200 yards in mild conditions and could barely keep them on paper. Slugs at 200 yards in similar conditions I can keep 1-1.5MOA groups still. 

Slugs can shoot well even at speeds in the 800's. I'd suggest picking two target tune areas some distance apart (like maybe 850 and 900fps) that offers acceptable shot count then shoot a couple test groups. You will know right away if your gun/barrel likes the slugs or not. Unfortunately not a lot of variety in the .30 slug market right now.
 
The hammer in the DW is massive and few realize just how much that effects shooting the gun accurately. My experience with the .30 was that it had extreme muzzle jump (regardless of power output) that in turn frustrated the heck out of me. I'm a very experienced shooter and in the beginning never thought it could have been me. In the end I had to make some adjustments to my normal shooting style and found that my accuracy improved drastically. My advice is to purchase a good rail extension to get the bipod further out front, that helps.

Ah Hah!  So it was not just me who experienced this! I have not been out with the DW since putting the H&L lower pic rail (Kraford &Lypton but I am now looking forward to going to the range again. thank you! I noticed that if the gun jumped at all to the left or right in the firing sequence my shot would be crap but if I could keep calm and not hold the DW too loosely I could on occasion get my pellets stacking.

Thank you again, Dana!

Just a couple of tidbits...

Dana, the hammer actually weighs a little less than the RW hammer when I weighed them sometime back. The valve opens easier and the ports are larger. More power available was the design intent. That said, I 100% agree about shooting technique. It's been difficult for me, for sure. It's the only bullpup I own so maybe I'm just not used to having it all by my face. Shoot the RW and DW side by side and it's easy to see.

On the 44s, if you check out JSB's BC chart, they are actually not that great so will blow more in the wind than quite a few others. I've had much better success with the 50.1s. Its interesting that the 20 cal Heavies (15.89) had an identical BC to the 50.1s which puts them significantly above the 44s. 

We have been using 130 bar for the 44 gn tune, if I recall correctly. The original factory tune tables called for WAY too high of reg pressure in the interest of being able to tune across a huge range of projectile weights. If you don't shoot slugs, turn that reg down and create your own custom tune OR disregard the flashing warning and stop when the velocity drops significantly . The rifle compensates for pressure when off reg just like a RW.

The velocity limitations are connected in the tables to caliber and weight. If you think it should go faster, use the custom tuning to do it. These tables have been refined SIGNIFICANTLY since mine was built but they are still evolving. When I refer to the tables, in Factory mode, the GCU looks at the velocity you in put, the caliber, projectile weight, and pressure and checks the appropriate table for a START POINT. It then modifies the parameters to achieve the results when you fire it. If it's not in the table, it goes to the closest one.... again only a start point. I use the custom sets almost solely .

Hope this helps some,

Bob
