My latest project was a new Weihrauch HW95 LUXUS in .22 caliber, purchased from AOA (typical great service from Rich). Upon arrival, I cleaned the barrel, tightened the stock screws, mounted a new Element Helix 6-24x50 SFP scope on top of Sportsmatch adjustable rings, sighted it in, and began testing, with virtually no break in period.
This rifle had considerable noticeable buzz in the shot cycle, more than I really found pleasant to shoot.
The groups were not good at all, though I am certain they would have improved after a 500 shots or more. The trigger was "good," but I knew it could be improved.
I reached out to Tom at Vortek, and within a couple of days, I had a PG3Steel HO kit in hand.
The rifle was stripped down completely. The piston liner was removed. The parts were lightly polished with 1400 grit emory paper, everything re-lubricated, and the Vortek Kit installed. It went in perfectly with no hassle. The only other work I did was polish the trigger sear surfaces, adjusted for perfect break, and lubricated it before putting it back in.
For those of you that wonder if it is worth it to go to this level of effort, you can see the dramatic and immediate improvements in the groups by looking at the 2 group averages in the accompanying test results chart as found below. While there are some anomalies in the chrono stats that I really can't explain, I believe they are more to do with the varying weight and conditions of the pellets than the rifle's power plant. The rifles shot cycle is now extremely smooth, with no "buzz," and only a solid thud upon report. The trigger is incredible. You will note that nearly every group average was significantly improved over the out-of-the-box testing results, and all groups showed at least some shrinkage. The power level actually increased with the Vortek kit while the groups significantly improved. I only expect these results to get better after a reasonable break in period.
