Weihrauch HW77K part 1

Buying a Weihrauch HW77K Air Rifle, part 1.

There’s a better than even chance that you are reading this article as part of researching the

Weihrauch HW77K with the view of purchasing the same. This is the 1st of 4 articles on the

HW77K range and will deal with the .177 calibre specifically, with each of the other 3 articles

concentrating on a different calibre and other aspects of this model air rifle.

The Weihrauch HW77K comes in 4 calibres, .177, .20, .22 and .25 calibres. In Australia the .177

and .22 calibres are the predominant sizes with a wider range of pellets being available in these 2


Where to buy a Weihrauch HW77K.

At Gun Room I stock the entire range of Weihrauch air rifles that are bought into Australia; that is I

have them here in stock and on the floor. Why?, because that is all I deal with in firearms,

Weihrauch air rifles and nothing else. I live in the country north of Perth and so I do not buy them

in from the  wholesaler when I make a sale as this is time and cost prohibitive. Furthermore, each

air rifle that comes out of stock is tested before despatch and this is only made possible by having

the stock to do it in a timely fashion.

I get a lot of feedback and enquiries about the handling and accuracy of Weihrauchs whereby it is

usually about a rifle that has been supplied by another dealer, untested and right out of the box.

Hence, I undertook to target test EVERY Weihrauch that I sold to minimise the time spent

answering phone calls and emails about issues with new air rifles, pellet selection or accuracy


Complaints about the HW77K often stated that the owner was disappointed with the accuracy and

when quizzed by myself, I am told that they are using some obscure and often cheap pellet type.

The issue is with pellet selection and not the rifle in 99% of cases, regardless of the make of air rifle.

Pellet selection is CRITICAL.

I test each Weihrauch air rifle prior to selling it using a minimum of 3 pellet types. If I am unable to get a suitable group then I expand the pellet selection until I find at least 2 good performing pellets for that particular gun. This is restricted to target results which as discarded once a suitable pellet is found.

I offer a Pellet Selection service for $60 (at the time of writing this) whereby I put through 6 pellet types, record the Chronograph readings and scan the targets for the customer. I am NOT tuning your rifle for this sum, merely testing it against 6 pellet types and recommending a suitable pellet. Being a new air rifle, it is not uncommon to find that pellet groups are quite ‘ordinary’ for a new rifle but rest assured that these rifles get better over time. The pellet selection test is similar to that depicted below and is emailed to the customer around the time of sending the rifle out.

For those of you who are new to air guns, let me say this much: no matter who has manufactured

an air rifle, be it Weihrauch, Cometa, Walther or Gamo etc., etc., there is no one pellet that suits

every gun or model. Every barrel is different and as such they perform differently with pellet types

and even pellets of the same type. There are some competition pellets that do perform well across

the board in Pre Charged Pneumatic (PCP) air rifles but these are usually after speed/power

adjustments to obtain the efficiency.

As I test Weihrauchs every day I have noticed specific pellet types that do perform well in these air

rifles, such as H&N Baracudas, H&N Baracuda Hunters, H&N Field Target Trophy, JSB Exact Heavy

and JSB Exact Jumbo Monster. However, this is not a given and it is not unusual for me to test 2

Weihrauch air rifles, one serial number apart, to find that the best performing pellet in each gun is

different due to slight variances in the barrels and mechanisms.

By testing each Weihrauch I sell, you can be assured that when you get the rifle it will come with a

test sheet (as below) and the recommended pellets for YOUR air rifle at the time of sale. This does

come with a caveat, and that is that the Weihrauch air rifles take at least 1500 – 2000 shots before

they are ‘run in’ so to speak, at which time I would, as an owner, retest the air rifle against some

more pellet types while only sticking to quality pellets. Pellet selection is paramount to quality

results, or as they say, “crap in, crap out”.

Weihrauch HW77K Pellet Test Sheet.

This following Test Result image is displaying a range of 10 pellets shot from a HW77K and one

should immediately notice that in this particular Weihrauch HW77K, the H&N Power pellets did

not perform at all in fact. The Pellet selection testing is usually done with only 3 pellet types and

expanded should I not find 2 pellet types that group well. In the HW77K case below I tested 10

pellet types using 6 shot groups to get the results.

This only goes to reiterate that pellet selection from a new rifle is a service that will save you both

time and money going through the learning curve yourself. Had this client not had his HW77K

tested prior to delivery and had he selected H&N Power pellets, you can just image how long and

loud he would scream at the poor results, and may even blame the air rifle. Best leave it to me to do

the screaming and test your rifle before I send it to you.

Advantages and disadvantages of the HW77K in .177 Calibre.

I often get asked if the HW77K .177 calibre is good enough to shoot rabbits, pigeons and rats etc.

Well this is a contentious issue as the rifle is quite effective at killing large vermin like rabbits, but

are you the shooter, accurate enough to do a one shot kill?

In the UK where they have power restrictions on their air rifles and they are limited to 12 Ft. Lbs.

of energy, the Poms have taken their shooting to the next level, and that is accuracy. So it is often

seen on You Tube and on Forums guys stating that they take out Rabbits at (let’s say) 40 metres

with a HW77K. I don’t discount this as some of the best air rifle shooters are Poms and while they

are hopeless at Cricket, they do however perform well with air rifles.

In Australia where our air rifles come into the country predominantly in the FAC* versions, a large

number of air gunners here seem to think it is power that kills, when in fact it is placement. Put

a .177 pellet in the right place when shooting a rabbit with a HW77K for instance, then you can be

assured of a clean kill. What concerns me is that many Australian shooters lack the skills, patience

and diligence to effect a clean kill and I see this as wounding more rabbits than are actually killed

in one shot. This is due in part to a culture here that power and speed is everything, when in fact

placement is really the key.

So to answer the question about HW77K in .177 being good enough to kill rabbits, it is if you are

a good shot, but if you lack the discipline to effect this style of marksmanship, then I suggest that you

buy a .22 or .25 calibre air rifle. That way, if your shot is not placed that accurately, there is still a

fair to good chance that the increased energy will in effect give you a one shot kill on a rabbit, as

long as you haven’t shot it in the foot or where-ever.

To my way of thinking, .177 is a great target calibre in a WeihrauchWeihrauch HW77K and effective on small

vermin such as rats and birds while the .22 calibre is best reserved for larger vermin such as

Rabbits. This is my opinion based on over 50 years of shooting with an air rifle and I am well aware

of people who are quite effective in killing rabbits with sub-12 ft. lb. air rifles, but in the

mainstream of shooters, the HW77K in .177 is less effective on large vermin when looking for a 1

shot kill.

*FAC stands for ‘Fire Arm Certified’ as the shooters in the UK have to get a Firearms licence for any

air rifle with the power exceeding 12 ft. lbs.

Weihrauch air rifle construction.

Weihrauch air rifles such as the HW77 series, HW80 and HW97K are all on the heavy side when

compared to some of the other manufacturers. This is a trade off whereby you are getting a high

quality German product at the expense of weight. It is not a big deal as some say it is, just get over

it and concern yourself with the quality product that will last a lifetime with minimum


The HW77K is available from Gun Room in the following guises as I can mix and match rifle stocks

to give you the product that you want. For left handers, I also keep a number of ambidextrous

sporter style stocks that suit the HW77 and HW77K range, while the thumbhole stocks are already

To do a full review of the HW77K is not possible in one article so I have taken the liberty of putting

further information such as break-down images of the air rifles, weights, sizes, V-Mach tuning,

performance and accessories, spread over the remaining 3 articles.

So while you are researching the Weihrauch HW77K do not stop on this article as there is more

information in the other articles that applies equally to the HW77K in .177 calibre as it does in the

other calibres.
