Ill buy all your once fired brass 75 for 250 pieces. Send me a PM....im not a fan of the set trigger. Annoying to set it 100 + times a day on the dog town. They say it also increases lock time, not sure how much it actually maters.The trigger on mine when not set was lacking. This is my 2nd 527. I bought this one used but never fired and it came with the timney. I really like it, but I shoot 2lbs on all my guns. Wish mine shot factory ammo like yours.I'm not going to touch the barrel, and the stock set trigger adjusts to 1 pound which is where I have it, the 17' hornet is not tough on barrels from what I know, only about 300 down the pipe so far in the 3 years I've had this particular one.All on varmints and brief sight in.As for the brass I can't even get 75$ for 250 pieces. Thankfully I stocked up on plenty 20 grain Superformance.I had the swat team supervisor measure this at work with calipers.I don't believe any barrel out there would outshoot it, everything came together under perfect conditions. I threw one shot low in the right hand target but knew it.I don't plan on missing much, but haven't seen one gh yet today.
