Your Guide to the Weihrauch HW100 PCP Air Rifle

The range comprises two full length rifles – a ‘Sporter’ or ‘HW100 S’, and a thumbhole version, known as the ‘HW100 T’ – and shorter carbine options, the HW100 SK and HW100 KT. All four are available with a fully shrouded barrel and are designated at HW 100 FSB models. In addition, there’s an adjustable brown and black thumbhole laminate option for the rifle and carbine, as well as synthetic soft touch black and green derivatives, all of which are also available with the fully shrouded barrel. Note that whilst the traditional and thumbhole stocks are ambidextrous, the traditional walnut carbine stock is designed for right-handers only with no left-handed option. Standard across all models are: an 11mm dovetail rail, 14-shot rotary magazine regardless of calibre, two-stage adjustable trigger and sidelever cocking system. In terms of calibre, all are available in .177 and .22, with .20 offered on some models. Power delivery is 12 ft. lbs. with higher-powered FAC options. All models take a 200-bar fill which is achieved by pulling a plastic stopper from the fill port at the top of the cylinder and inserting the probe. A manometer at the front of the cylinder shows fill pressure.

Weihrauch HW100 SK and HW100 KT

As you’d expect, the Sporter and Thumbhole carbine models are shorter, by a full 100mm in overall length and barrel, and, more significantly, by a huge 0.6kgs, making them handier, especially in confined spaces. Once again, .177, .20 and .22 calibres are available although shot counts drops due to a smaller cylinder capacity to 50, 70 and 75 shots respectively. High-power options are limited to .177 and .22 calibres with shot count dropping to 28. The oiled walnut stock has chequering on the fore-end as well as the pistol grip which is finished with a black cap. The rubber butt pad is finished with a white spacer, as is the pistol grip.

Weihrauch HW100 S FSB, HW100 K FSB, HW100 SK FSB and HW100 KT FSB

Fully Shrouded Barrel (FSB) versions of the full-length Sporter and Carbine models in standard and thumbhole stock designs are available. They are a little lighter than the standard guns at 3.4kgs for the Sporter and 2.8Kgs for the Carbine. All other features remain the same as the standard guns. 

Weihrauch HW100 T Laminate and HW100 KT Laminate

The attractive black and brown laminate stock with the added benefit of an adjustable butt pad is available as an option in .177, .20 and .22 on the Sporter and Carbine Thumbhole models only.

Best suited to

The HW100 range has become hugely popular with hunters and competition users alike and for good reason. The heavier Sporter model is popular with competition shooters but will serve hunters equally well.

Pros and Cons

The HW100 is known for good quality engineering which is most apparent in the side lever cocking action but is present throughout. Weihrauch has developed a reputation for offering some of the best triggers available and the HW100 carries on the tradition. The magazine design is simplicity itself and as a result is hard to beat. Like many other rifles in the company’s range, the HW100 is pretty hefty in the full sporter length, but beautifully balanced. Carbine models are more wieldy but offer fewer shots.

HW100 S vs HW100 K

The ‘S’ and ‘K’ models vary in length, weight and cylinder size. The longer and heavier HW100 S will deliver more shots that the HW100K which has the advantage of being lighter, more compact and easier to use in confined spaces. Thumbhole stock ‘T’ variants have a different aesthetic appeal and grip.

HW100 models vs HW100 FSB models

Without a silencer fitted, FSB (fully shrouded barrel) guns have the benefit of being quieter but are identical in every other way to other models in the range.
