Getting my D-34 Tuned

[cnjl3]

So what kind of groups did your D-34 give you initially? Did your group size open up and that is why you decided to go for the tune? I always wondered what was involved with a professional tune. Check out what Mr Paul Watts has to say:

This is the first part of my rifle tune review:

I just got my rifle back from the tuner and from what I have seen so far it is wonderful.

First let me state the rifle only had between 1000 and 2000 shots on her before it went to Ed Krzynowek. Upon opening her up he found the spring broken in 2 places leaving me with a three part spring, which is good for a pool cue, but not for a spring rifle.

His tune consisted of a trigger tune which was adjusted to 12 oz as per my request because I use this for a target rifle.

JM GRT kit
JM Apex Seal
New Breech seal
Crossed hatched the piston
Deburred the rifle
crown work
Put washers in my Droop compensator mount.

Hand Lab the barrel
Added 3oz weights to the butt of the stock to make her balance better
He did some extra breech work
He also carved notches in the stock to make easier access to the bolts that hold the cocking lever. (A very nice and professional touch) He did much more that I can not remember it all.

My rifle had so many little things wrong and it looks like he caught them all, his attention to detail is outstanding.

We discovered which pellets shot most accurate:
1) RWS Superdome 775 fps
2) Crossman 770 fps
3) H&N 14.66 5.53 head 750 fps

I have only fired the rifle about 10 times since the tune and will try to give a full report later this week end, but for now all I can say is she is sweet. She cocks very easily, fires with almost no recoil, and you hear a thump with no twang.

Ed will be sending me pictures and if I missed anything else that he did I will report that also.

So far from what I have seen before my testing, do yourself a favor and get your favorite air rifle out and send it to Ed, if you are like me and scared to do it yourself. He knows his job and does it well.

That sounds like it turned out really nice. Enjoy.

Mine is probably right around where yours is numbers wise, but my tuned 34 kicks almost as hard as my AR-15. I think one of the things about springers is the recoil. The AR has a slight power advantage though LOL. My .22 Bolt action rimfire rifle's recoil is nonexistant.  .

Anyway, I'm surprised about the low-recoil. Do you have a muzzlebrake?

[Booger]

No muzzle brake. Just seems to be a great tune and less noise, but noise does not bother me because I live in the country.

Congrats on the tune! It sounds to me like a solid value for what you paid.   The velocity numbers look great.  Just out of curiosity, what were your pre-tune velocities?  I have a new 34 T06 Classic, and was wondering how much velocity you gained, if any, with the tune.  Thanks!

LOL.....and some folk don't think a tune would make a big difference! While my .177 R9s have all been accurate from the box, they're not really pleasant to shoot till I've "de-twanged/de-vibrated" them!

Anywhoo.......great report, thanks for sharing!

My pre-tune velosity numbers were:

Avg         Ex Spread   Stan. Dev            Energy
689.6   14.3              4.3                 15.10380839

I am exhausted, but I would like to share some pictures. Hopefully I will have more results tomorrow or Sunday.

I have been out of town for a week and missing on shooting my D-34. After a 4 hour drive in the rain I got home and the skies were clear and very little wind. The first thing I did was go to my gun cabinet and pick her up. It is such a pleasure to cock and shoot her. The action is, to put it in one word 'sweet". When I first got her I had a hard time getting 1" groups at 10 yards, but now after the tune I got a 2 1/2" group with 10 shots at 40 yards. As I am shooting her she is getting tighter and tighter. This was money well spent in my opinion. I have my TX200 being tuned now and my D-34 .177 is next. After that I might need to find a good tuner for my next rifle (maybe a PCP).

Edit: This is closer to a 2" group. The target is 5 7/8" circle sold at Walmart.

[Booger]

She is still being broken in after the tune, and wow what a difference. Check out this 10 shot group at 50 yards. Each square is only 1" and is sold at Wally World. I do not think I want another air rifle that has not been tuned. This should end my review, if anyone has any questions PM me and I will tell you what I can.
