Well, this is one of 'those' threads which will keep getting ressurected.
I recently got a HW 77 .22 25mm which needed a bit of tlc. I have not had a chance to shoot it much yet. I didnt fancy spending a fortune on servicing it. Luckily, this being an old classic, there is a lot of stuff on the web, on how to strip it.
With 3 in 1 oil, and 0000wire wool, I took some light rust off the barrel, then washed and degreased it. Cold Blued with some G96 gun creme, on some bits of the barrel. Its an acceptable finish for my use.
Cleaned the barrel. Then lightly sanded a new piston seal with 1200grit emery and made two washers out of a piece of 1mm delrin.
One to go on the main spring guide, and the other on the piston end. Also added a new breech seal.
I Put 3 steel washers on the piston end, under the delrin, and one steel washer on the spring guide and mixed some white lithium grease with ptfe spray and lubed it all with that.
I think that made a difference.
The results from the chrono app on my smartphone seem pretty consistent:
579, 580, 579, 579, 579.
Using JSB match 15.89gr pellets. So it seems to be shooting bang on 11.8 ft/lb. at the moment.
Then in keeping with the period, i acquired a scew on whisperer silencer, and a silencer adaptor, and fitted those. Then fitted an adjustable butt plate, and bought an MTC Viper Scope.
I just need to get out a bit with it now, havent shot for a few years, find a local club/shoot, and a permission. Squeeze some shooting in between bushcraft/canoeing/fly fishing etc...!
Im very happy with it though. Classic looks and a really accurate rifle, which neednt cost a fortune.
Probably put a sling on at some point as well.
I dont know what you guys with the Pre charged rifles are gonna do, when civilisation crashes, and you cant bag dinner.
When that day comes men with springers will rule the world!
Anyone else a Fan of the old Weihrauchs?
