Weihrauch HW100.

[Steve K]

All guns can have issues, but if you have an HW100 in perfect working order (most are) then it's a tough act to beat imo.

Never had issues with the two piece action, in fact the only issue i had was my .22 went a little low on power, a good de-grease and clean of some of the internals sorted it out straight away.
Imo, HC put too much grease in the mechanisms, the grease thickens in the cold, and slows the way they operate.

I chrono mine on a regular basis, and it's unbelievable how consistant the readings are.

Definately keepers!

Agreed. That grease really holds them back, but it's easy enough to get most of it off, even with the AT version.

I've tuned mine, which involved a de-grease and they have no power fluctuation - just a steady 11.25ftlb all-year-round, from freezing mid-winter through to scorching summer.

Ever since my thread earlier this year entitled; "Do I need a HW100!?!" I've loved every minute of ownership

In terms of the sales stuff, you'll always see loads for sale, as they are incredibly popular. Think of it as a 3 Series BM, you see stacks in the classifieds because there are stacks on the road, not due to any inherent fault.

Faults are funny things though, and it's easy to get wound up in the moment - just bear in mind that nobody ever posts "HW100 working fine today, just like yesterday" - doesn't make for the most interesting thread

Interesting thread this, I do have a soft spot for the HW100, and kuro good point bud

Fluff, something else I've always wondered is the HW100 actualy 100% Regulated or is it semi regulated? I've heard so many people say this and that etc, and to be honest semi regged what the heck does that mean

It has a mechanism that equalises the velocity from shot-to-shot, so yes, as far as I'm concerned, it has a regulator, even if the reg design is unconventional by being external to the air cylinder.

Here's a full-fill shot-string from my .177K taken during my tuning process (s/n 1909043, 11.1ftlb average energy across the whole charge), using unsorted JSB's/AA's (with known variation of 8.2-8.7gn, which accounts for most of the shot-to-shot ft/sec variation if you do the maths).

Wow thats impressive Fluff, all those shots from a Karbine thats about double the norm over a standard Karbine, even Weihrauch have it listed on there website as 50 shots in .177K guise. thats some nice tuning

I notice you have a .22 HW100 as well, I've never shot the .22 HW100 before and without wishing to get in to a calibre debate as its horses for courses etc how do you find the .22 flavoured HW100 Fluff?

Thank you. I'm rather proud too. One or two bbs members have done a full-fill chrono to verify the shot count and power.
It has no temperature-related power fluctuation and the regulator will function up to 220-230bar, meaning that it could manage an extra mag or so of shots, if slightly over-filled.
Not that I recommend it because 200 is the max recommended in the manual - but many "professional tuners" raise the working pressure of their "tuned guns" from 200 to 230bar as part of the enhancement process.

I have a mix of .177 and .22.
The .177 is more versatile, but the .22 is more reliable at putting the rabbits down, if you can get within 30-35yds.
My .22's are generally used for NV work, where getting close is easier than in daylight. My .177's are generally used for daylight shooting. I have the Rapid .20 because it's calibre is a good all-rounder that I'd take as my first choice if checking out a new shoot (due to unkown ranges and unknown location of warrens).
