HW/Weihrauch Anyone install a Hw30 ARH kit lately?

Yes, I installed an ARH kit with the Vortek vacu-seal in my R7 this past March. Last check shooting 7.5#, give or take. I can chronograph a few pellets and see where it has settled in at. You're not interested, but I used the Vortek PG4/vacu-seal in my HW30. For accuracy, it will give the FWB300s rifles I own a run for their money. The HW30 is fantastic. The R7 is pretty good. The HW30 may just have a better barrel. Both behave well and are a pleasure to shoot.
 
Small world, wouldn’t want to paint. Just changed a R7 last night. Thought I had some vortex springs, but I didn’t, just put an old slightly used HW 30 spring and that I have. I will order a few ARC sets to compare.

This spring is a little distorted.
Thanks for the reminder. Crow

Most all Weihrauch springs turn into snakes with use. I'd almost bet the gun with the distorted spring didn't buzz. Big distortion usually causes the spring to lean hard on the piston skirt, deadening buzz. This is why people say the buzz goes away if you keep shooting it. Indeed it does but on this model the cocking foot will rub on the deformed spring when cocking and or closing the gun. You'll feel it skipping over the spring coils. I've had several Hw30s/R7s sent to me like this. Including the R7 I'm doing now.

This is a very very low use R7 from 1985 and the spring has already started to snake. It wasn't distorted enough to deaden buzz but it distorted enough to feel the cocking foot skip over each coil. Weihrauch springs from at least 2015 don't seem to last. Some brand springs go soft and collapse. Later Weihrauchs run hard until they break. My 177 Hw95 spring came out in three pieces and was still shooting 800fps. The best I can remember that gun was never dry fired. Dry firing these guns shortens the life of a spring drastically. Oddly you can infinitely dry fire a HW45 without damage. Don't ask me what the difference is. I've proven both situations several times.
