Tuning PCP rifles?
« on: November 13, 2009, 09:46:14 AM »
I read a lot of tuning spring powered rifles and it is supposed to help a lot. Have only shot one tuned rifle, a buds Diana model 48. I didn't try it before his tune but it does work very well. He says it was a big improvement all around.

Does one need to do some tuning to PCP rifles? My Evanix Blizzard, maybe? What would one do or have done and how would it effect a rifle that already seems to me to be great?

Like any air rifle there are of course things that can be done to  tune a PCP for enhanced performance but if the rifle is shooting well it's not an absolute necessity.  I've never personally tuned any of my PCP's so I'm certainly not qualified to tell you what to do with yours, but if it's already shooting "great" and you're apparently more than satisfied with it's performance I would say just leave it alone, shoot it and have fun  :)

If you have the money to spend, or just want it tuned, then I would contact one of the professional tuners out there and speak to them about working on your rifle....

I have tuned some PCP's, and it's not that much different from tuning a springer in some ways.  Although not nearly as big, there is a "main spring", actually a hammer spring, and the hammer or striker is somewhat similar to the piston.  And of course there's the tube the hammer slides in, which is similar to a springers compression tube.  All these parts can benefit from some polishing, deburring, and lubing, same as a springer.  But it really depends on the gun.  I've worked on the lower end guns, a BAM B-50, a couple of Air Force Talons, and my Hammerli Pneuma.  But I never felt the need to do anything to my better guns like my AA's, FX, and my latest, the Evanix Renegade.  I'd say this is a case of if it works, don't fix it ;-)!  Later.

I have two Discos, one tuned and the other stock. The tuned on has a better trigger, two barrel band and a ldc. They both group about the same. I guess I got luck on the stock one as it is a shooter. The tuned one I bough used that way.

I would say shoot one first before investing in a tune it may not be necessary. All I really need is a TKO trigger replacement for the stock one and I will be set. I don't need a ldc on it as I live in the country and personally I don't think the stock Disco is that loud.

In shooting today at 50 yards I took a couple of pigeons with one shot kills. They are easy to hit as they sit on top of grain bins at the grain elevator. The guys at the elevator love seeing them hit and falling to the ground and the neighborhood cats have a feast later.
I will hold on doing anything until I talk with others who have a Blizzard and see if real world experience with tuning/tweaking makes anything better. I understand about 'small increments' of improvement and don't expect anything major. If there are small things that can be done to finesse the rifle I will try them. Later though as I am still getting used to it. Had a friend with me when we went to the grain elevator and he was impressed at my shooting. I let him shoot and he was surprised at the power of the rifle and how quiet it was.

I can't imagine much tuning, if any would need to be done to a Blizzard. I've only heard great things about how good that gun is bone stock. You should post pics of any future pigeons you drop with your Blizzard!

Yes, the rifle is nice. Good looking and it shoots well. Sure does hit hard and is very, very easy to shoot. Quick cocking and the ten shot magazine makes it good for follow up shots. The thumbhole stock is good and comfortable for me in use. It is not heavy and sure does handle well.

I asked because of reading of tuning for other rifles. Shooting my friends Model 48 and his experience had me wondering.
