I thought like you stretch I wanted my .17 Kral to shoot heavy .17 ammo. I’ve settled for the 10.5 weight. Very accurate

Show us your Krals!

- Start date
Mine shot those good too, but I can't find them local, so I switched to the 7.9 at Walmart. They shot just a bit better, and I was able to run the lower power tune and conserve air. That gun was a sparrow reaper.

Allowing hammer free flight improved my Krals greatly.
I am working on a debounce device for my BSA Ultra which is generally very accurate too except for a couple of shots per fill.

I just picked up a scorpion a few months back and now have a gently used ultra coming from AoA.
I've had the scorpion up to 50 fpe, but only 15 shots. Going to try and tune it for slugs around 45 fpe for 20 shots. The ultra will be brought up to about 15 fpe and used for bird pesting. Awesome guns.

Thanks for the reply. Regarding your remark about velocity, the gun is outputting just over 12ftlbs and its .177.

Hi Pete
You will enjoy that
Its annoying when things like that start happening pete it then turns in to a process of elimination.
I'm sure at the end of the day you will have found the cause one way or another.
Hopefully you get it back shooting right
I have abit of work to do to mine aswell as not quite 100% how I'd like it .
You will have anti tamper screws in your gun pete not allowing you to remove barrel and adjust hammer etc
Regards
Paul

Ok, this Puncher Breaker has me completely confused. This morning I cleaned the bore and it was filthy! Three wet patches and four dry patches later it was clean. Then I shot 6 rounds over a chrony with the Crosman 10.5 gr pellets to adjust the speed to around 850 fps. Then the next 5 rounds looked like this:
Great! I could have pulled that one shot and I'm thinking that was the problem, the bore was dirty. Then I shot 3 more magazines and it's hitting all over the place. Here's what another target looked like after shooting a full magazine (14 rounds) at the same aim point. Some shots were almost a foot high or low. I've never seen anything like this before.

I've seen shotguns pattern better, damn.
You might have a bad barrel, but it makes no sense for it to shoot good, then go to hell like that.

Just had the 25 cal jumbo out, on a bipod rest and shouldered. Getting eaten by bugs, but I still got some good groups. Only to 35 yards, but the groups stay pretty tight out to 75.
The left is baracuda 30.86 grain
The right is jsb 33.95 MK2
Both are 10 shot groups! The flier on the baracuda was all on that damn aphid crawling on my open eye not behind the scope

My shooting station lol. The notos is laying next to the jumbo, for any of those close in pests I don't need 50 fpe for.

Trigger work complete on np02
Now no twang or bounce and smooth as silk.
Next on the list is the barrel.

It's a Puncher Breaker, and yes (as I posted in an earlier reply) I tested it with the shroud, without and with a separate suppressor. No change.

My bad, I've been skimming the thread lately.
You can always try ordering a new barrel from PA or CSS. I would personally put an np03 16" barrel in it, and use the muzzle bushing as an air stripper. Drill some holes all around it to vent into the rear of the shroud, and get a stack of Mrod baffles. It'll make it about as short as you can get, and quieter than with a tanto IME. Swap a short/stiff spring, tune and run it.
In 177, set up the way I described, you should get about the same power, less noise and more efficient. I was getting 60 shots in a 22 breaker with it cranked to 36 fpe out of the 16" barrel, and it was super quiet. Stacked polymags and hades all day.

I've only had the rifle a couple days so before I start investing in modifying the rifle I want to see if it's worth keeping first. If I can't figure out what's wrong (or if I do and it requires new parts) I'll just return it and get an Akela. I know I can get replacement parts from Benjamin.

That stinks man. It is an odd problem
Scope ? Any chance ?
No new gun should be this much hassle Return it ….

The scope is an Athlon from another rifle that I haven't had any issues with, so I'd bet money that isn't the problem. I'll give it another try tomorrow before the wind picks up. If I can't figure it out, I'll probably return it.
