Derya DYBA 9mm bolt action range report

Well I took mine to the range today. Put 60 rounds through it and it was pretty fun. We tried 4 different types of ammo in it and accuracy was not great with any of them. We had 3 failures to feed, 2 with the supplied mags and one with a single stack 10 round Glock mag. The rest of the ags seemed to feed flawlessly.

Accuracy was around 6" at 25yds with 3 of the loads but it grouped around 4" with some 147gr lead round nose handloads of mine. I have a Leupold VX1 3-9x40 on it right now but it will be replaced with something smaller and more compact in the future.
That's crappy to hear. My ruger pc9 made ragged holes with any 9mm ammo at 50m...... f'n libs
 
Finally got to take mine to the range a few days ago. I was using 115gr Blazer Brass and had a 1-4 Vortex Crossfire 2 on top of it.

Reliability: I only did a quick wipe down of the internals before I shot it to take that into account. I found the gun fed 100% of the time, though the bolt was tight in the receiver so would sometimes take a bit more force to cycle. The biggest issue was that sometimes the brass would not eject out of the gun; it would extract from the chamber and then just lay in the action. This could be a gummed up ejector issue as I only wiped down the exterior of the bolt before I shot it.

Accuracy: I only had the 115gr Blazer with me and zero'ed it at 50m. Once it was zeroed, I shot 4 five rnd groups. The all the groups were within 3-4 inch groups at 50m. I pushed it back to 100m and saw a drop of about 7-10in and a grouping size of around 7-10in. Some of the grouping size may be human error; I was using my ammo bag as a rest and I'll cop to not being a precision shooter.

Ergonomics: Rifle felt fairly light weight in the hands. The included mags were... stiff... to start with though did loosen up alittle after a few reloading cycles. The mag release is... interesting; due to it's design there was a fair amount of flex to the mag release lever and sometimes I couldn't find it with my finger unless I hunted for it alittle. Generally it ejected the mag when I wanted to eject it so I guess it did it's job. Very little recoil as one might expect from a 9mm rifle and all together a joy to pull the trigger on (got a bit of that hollow thunk whenever it fires).
 
After a solid afternoon shooting at 25 and 50m I can't say I am doing any better than others. It's odd for me, I stack 2 or 3 bullets on each other then 1 or 2 go wild. 3" is the best group I can manage for 5 shots.

I brought
-Winchester 9x19 NATO
-Campro 124RN loaded with W231
-Hornady 124 XTP loaded with HS-6 (+p)

I had a cheap 3-9 on it. I took it off near the end and used the irons to shoot some 3-5" groups so I think that is the best I am going to do with the ammo I have on hand, maybe just in general.

I am still happy with it though I wish it were a bit more capable. The groups with the irons were acceptable like with the optic but they were several inches right at 50m. With my sight already canted left I am stuck using Kentucky windage.
 
I was shooting mine this past weekend and had poor ejection as well. First time it has happened. The first 6 rounds out of the mag didn't eject but then it started to again. The ejector is a goofy setup and I think it can stick quite easily. I can make it stick back quite easily if I push it with my finger.

Accuracy is still very poor.

Ouch my Lee with a 70 year old SMG barrel can do way less than 4inch.

Would love a 9mm bolt or pump, but seems to be lots of complaints. I’m not familiar with Derya, are they the kind of company to come out with an improved Gen 2 version?

Maybe the lever action pistol caliber carbines on the market are a more reliable option for a non semi in a pistol caliber.

That "Gen 2" question is a good one.
 
Tikka expectations on a Türkiye budget

The DYPA is a fine range toy if you dont expect match performance, alot of you seem to be forgetting your shooting a pistol round

No doubt the Turks can do tweaks, I think a big driver would be an importer that is hands on and actively interested in improving the products that they import into Canada. This would look like a company that is active on the forums and responsive to customer feedback.

North Sylva is the current Importer and in the many years they have been active (posting when it suits them) on CGN they seem to be less then fully turned on and tuned in when it comes to customer questions and concerns.

They strike me as a "me first" operation unfortunately.

I wonder if it would be different with a heavier/recrowned barrel; I know some of the heavy-barrel .45 acp Enfield conversions were doing ragged holes.
 
I had an opportunity to shoot my Homesteader in a very controlled environment today. It is doing better at 100m with an ACRO P-2 than I did with the Derya at 50m and a 9x scope. I still like the thing but it seems to be a bit meh in the accuracy department.

Nope!....:(

I bought two brand new Ruger/Marlin 1894 Trapper stainless & laminate 10mm lever rifles. The first needed 2-3 hours of internal polishing just to cycle, fire, and eject without jamming!..........:oops:

The second was okay from the factory. Both guns shot 5"-6" groups at 30 meters. With factory Hornady 155 grain XTP ammo. (1673 fps)
And with Hornady 180 grain XTP factory ammo. (1470 fps)

My Remington/Marlin 1894 CSBL in 357 magnum will shoot factory S&B 158 grain JSP ammo into 1" at 50 yards. So it wasn't me the shooter.........:ROFLMAO: About the same with Federal 158 JSP factory ammunition. (both around 1700 fps)

I do love the new Ruger/Marlin lever guns, just not the 10mm Trapper Model......:(

I own a few other Ruger/Marlins, and they are very accurate.....:)

My point is the 10mm pistol caliber was not accurate at all in these rifle carbines, this has not been my experience with 9mm carbine rifles, so who knows if a 10mm auto can be made to shoot more accurately in a rifle?

I was extremely disappointed in Ruger/Marlin's new 10mm Trapper. Other peoples results may vary?.......:)

I too have a new 10 mm Ruglin.
Haven't had the time yet to set up in the back yard and try it out. You have me a little worried now.

On the Derya 9mm bolt rifle, I did put rounds through my new one in the last few days, and I love it. Very nice trigger out of the box.
It was starting to smoothen out nicely in it's feeding during that session.

Same day as the above 9mm, I also tried out a new Ruger 77/44. Terrible trigger, so much so it was not really possible to accurately sight it in.
I'm very disappointed in this one.

I hope I haven't ruined it for you with your Ruger/Marlin Trapper.....:( I have not heard of great things with this particular 10mm auto rifle. Yours may be different. If not sell it off with full disclosure. I sold both of mine.

Those Derya 9mm bolt guns are a 100% no-go for me. Way too many issues, and accuracy seems to be poor as well.......:unsure:

Your Ruger 77/44 can end up being an awesome, reasonably accurate rifle. I have owned every 77/17, 77/22, 77/357, and 77/44 model that were made. I still own several. They all need to be bolt shimmed and have the trigger worked on. I will attach several links on which items you will need. A Volquartsen or Timney Sear, a trigger return spring, and new bolt spring if necessary will bring your trigger pull down to 2 pounds or less if desired. The Ruger 77/22, 77/44 models are a well built reliable and an accurate rifle to shoot and own. The bolt shims creates a better head space for accuracy as well.
