I'm a little more than idly curious - perhaps because I know for a fact that while Weihrauch produce excellent rifles, they know very little about producing coherent marketing material. Such as a product brochure that answers this fundamental question about each rifle: What's it for?
Even more confusing is that the model numbers seem to have been arbitrarily assigned, so you can't navigate their product line-up by making the assumption that "Greater product number = more advanced rifle".
I know I'm not the only one who's confused, because companies selling these guns usually don't give their own description of them. They just copy and paste the standard marketing blah-blah-blah from the Weihrauch catalogue.
As far as I'm currently able to tell, and leaving out their pistols and rimfire/centrefire rifles, their pellet rifle line-up have the following major roles.
Can anyone add to, or help correct, these definitions?
(And, No, right now, I do not have anything better to do.)
HW30 M / II
Entry-level break-barrel target rifle for juniors.
30 M / II with interchangeable front sight inserts and 'Rekord' trigger.
HW30S with 22% more power.
HW50 M / II
Entry-level break-barrel target rifle for adults. Basically an HW30 with 32% more power.
50 M / II with interchangeable front sight inserts and 'Rekord' trigger.
Entry-level adult rifle. Underlever cocking, but otherwise, same basic specs as HW50S.
Upgraded HW57 with 16% more power, removable front sight and slightly more luxurious stock.
Modified HW77 with muzzle brake, no iron sights, and wider choice of stocks (including thumbhole stock). Developed specifically for Field Target.
(The 'K', for 'Kurz', or 'Short', comes from the 97 having a 170mm shorter barrel than the 77 because of its integrated muzzle break - even though the 77 and 97 share the same power plant and are about the same overall length.)
Adult break-barrel rifle with Theoben gas ram. Made specifically for open-sight hunting, but accepts scopes as well. Power adjustable from 'That tickles!' to 'Put-that-thing-down-and-back-away-slowly'.
HW50 with longer barrel and 18% more power.
HW80, but with a basic Walnut stock instead of Beech.
HW80 with a choice of two even-more refined Walnut stocks.
Break-barrel, designed for precision shooting at longer distances. Heavy barrel, fully adjustable stock, no iron sights. Slightly less power than HW80 and derivatives.
Weihrauch's take on the Air Arms S510. 'Spare-no-expense' 14-shot lever-action PCP.
Weihrauch's take on the Air Arms S500. Single-shot, but otherwise identical to HW100. (This gun doesn't appear in the 2018 Weihrauch catalogue, and I've heard people say that it was discontinued.)
HW110 ST / STK
'Budget' 10-shot lever-action PCP. Simpler action than the 100, polymer-based construction, Picatinny scope mounting, soft-touch stock only. The ST ('Soft Touch') is the standard-length rifle. The STK ('Soft Touch Karbine') is a great deal smaller.
(Confusingly, these guns don't appear in the 2018 Weihrauch catalogue either.)
