I finally got some time to get the barrel finished up and installed on the rifle for some testing.
Attachment 506
First thing I noticed when I chambered a pellet was the throat lead was too tight and would need a bit more work with the reamer.
Here is the rifle with the first 5 shot group, Meisterkugelns at 10m. Not too bad for the first 5 shots through a new barrel but something is obviously not up to snuff

I took the barrel off again and eased the throat lead a bit more and repolished.
The next 5 shots looked a lot better

And it passed the Anschutz test

I still have to test a variety of pellets at different velocities to see how fussy this barrel is. ( I'm guessing it wont be) but I'm pretty happy with what I'm seeing here with a randomly selected pellet.
:hmmm: me like!
Great results, Sean! :encouragement: Nice work! Wish I had the tools and talent to do that...
Just about finished my latest project, then I'll be able to start .25 cal LW Disco project. Can't wait! :eagerness:

25 cal LW Disco sounds pretty sweet too. What was the latest proj...and where 's da pics dude
I don't want to hi jack your thread :icon_redface:, but seeing as it was you who asked....it's nothing special, just a skeleton version of Bob's 2260 HPA (which I used as a guide), and still a work in progress. My first HPA build where I did all the work myself - with my limited tools! (valve, HPA setup, shroud, etc...). Figured if I was going to learn how to do it right, I may as well learn from one of the best. Hope you don't mind, Bob! Not as hot as Bob's, though - 14.3 gr Benji HP @ 957 fps, 16 gr Polymag @ 930 fps.
...And before anybody gets excited about the shroud - it's purely cosmetic (no baffles or such). Unfortunately, it still sounds like a .22 lr...:icon_rolleyes: Now, if you want to see some real quality craftmanship, check out the fancy butt pad! :highly_amused:

Excellent work there Sean. Had an opportunity to shoot mine today as well...I am a happy camper.
Todd that looks awesome. 930 fps with polymags :icon_eek:.....That's SMOKIN! Let me know when your shooting it and I'll be sure to stay low or indoors.:icon_mrgreen:
That's great to hear Al. It's nice to work with such a fine grade of steel. What are your thoughts after having done one. So far I have not cut the slot for the barrel band screw. And at this point I don't know if I'm going to. If I do I will likely move it much closer to the breech.
Sure was nicer to work with than the Crosman barrels. I fitted mine a bit non traditional for a qb...more like a polytubed Crosman....that fits the receiver. It's floated as well. Made a pellet tray from delrin that fits a bit closer as well. Seems to take most of the slop out of the bolt when clambering...but such things are subjective. Shoots like a house on fire now. Tried cphp, ultramags, Jsb's in 8.4 &10.3grs , and baracudas ....all were good. Certainly not fussy but a slight preference for the heavy Jsb's.
Will be making a velocity adjuster this week for further fine tuning.
I also was thinking of making the pellet tray separate from the barrel.... I presume that is what you did?....
