A Hunters Review of the SMK TH208 .22

I am a simple man living a simple life, snippets of which I publish on my blog www.1nomad.blogspot.com.
The meat I and my family eat is procured from the wild, and I choose to hunt it with an air rifle. Recently, I found myself in the market for a new rifle and not wishing to dice with the uncertainties of the second hand market, I desired a brand new one. But which one? The market place is awash with offerings but very few within my budget of £250. I went direct to SMK on the strength of their 40 year reputation for affordable rifles, and put my plight to them in writing describing my situation and my needs. The recommendation from them was their flagship model, the SMK TH208 .22, and shortly after, I had one in my possession.

Upon inspection it was quite apparent that here was a rifle that was loaded with the sorts of features I had only seen on those costing nearly twice the £199.95 price tag of the TH208. The first to jump out of course is that thumbhole in the hardwood stock. I am a big fan of this feature due to the way it enables the shooter to comfortably tuck the rifle butt into the shoulder and gain a secure hold.

The Thumbhole Stock is both comfortable and practical.
The light chequering on the foregrip is a welcome bonus and added to my overall impression that this was most certainly an outdoor hunting rifle.

Chequering aids grip in wet conditions.
 
At the rear of the action, sits an automatic resettable safety. This, for me, is exceptional. I cannot tell you how valuable the ability to reset the safety is in the field and many hunters will attest to the piece of mind gained by being able to make your rifle safe if your quarry evades you.

Moving forward along the action of the TH208, you have a scope arrestor plate fixed to the sight rail. Evidence again of attention to the hunting shooters needs, after all, accuracy is paramount and ensuring your optic doesn't creep and constantly re-checking zero saves a lot of pellets!
The TH208 is finished off at the business end with a barrel weight intended to reduce muzzle flip and enhance accuracy. Yet another feature with the shooter in mind.

Needless to say I was itching to get this equipment out into the field, but as is my habit after only being able to afford second hand rifles, I stripped the gun down and gave the internals a cursory clean and regrease. By doing this, I was able to fully acquaint myself with the essence of the rifle and was most impressed by its simplicity and the workmanship I discovered.

Next, the SMK 3-9x40 mildot scope was mounted on solid Sportsmatch mounts. Now I had an excellent sight picture right out to the limits of my hunting range in a very sturdy looking optic.

I'll admit I struggled at first to get consistent groups until I realised my over exuberant 'breaking' of the barrel had knocked the barrel weight loose. This was quickly remedied by simply tightening the two grubs screws located on the underside and the resultant accuracy was staggeringly good. I later removed the barrel weight in favour of a silencer, but found it needless as it added considerably to the length and muted a muzzle report that was already acceptably low.

I found the factory setting of the trigger to be just a little too far back for my personal taste, but as the trigger is fully adjustable, I had it exactly how I liked it within seconds thanks to the easily accessible screw and found the trigger release to be fast and crisp.

Among the many features, deep blueing like this makes the SMK TH208 exceptional value for money.
The TH208 punched consistently tight groups from 10 yards zero out to 25 yards (the limit of my woodland 'range') with the phenomenal ThUnderBolt .22 zinc pellets that had been supplied. This performance bodes very well as the rifle has yet to settle down and 'bed in' and, hopefully, this shooter will improve too!

The ThUnderbolt .22 Pellets were not only accurate and consistent, they packed a punch too!
The SMK TH208 is capable of putting the pellet exactly where you want it.

Results were equally encouraging over the chronograph with the ThUnderBolts giving low (18fps) fps variation at 10.7 ft/lbs. Ample power for hunting that usually rises over time and with use, therefore, investing in a small chronograph is highly advisable for all airgun owners.
Interestingly the TH208 did not seem to mind which pellets were used unlike some that can be very pellet fussy.
AA Field Diabolos, Bisley Superfields, RWS Superdomes, RWS Superfields, Norica Apaches and SMK Spitfires all grouped very well. I did find that the pellets with smaller heads and thinner skirts fared best and the ThUnderBolts appeared overall to be the perfect match.

The TH208 truly is a pleasure and a joy to shoot. I confess that I probably got carried away with my accuracy, pellet, and power tests, but I firmly blame the TH208 for the enjoyment it imparted, willing me to fire just one more pellet. Be warned, this feeling does not appear to wear off and firing nearly a whole tin of pellets and making small ragged holes in at least one packet of paper targets happens far sooner than you would expect!

I set out to buy a capable hunting rifle. Weight wise, the TH208 is heavy enough to keep the effects of recoil minimised, but still light enough not to wear out your arms and this makes target acquisition very quick and easy indeed. It is sturdy enough to take the numerous knocks and bangs any gun that lives outside of the cabinet can expect to receive and, for me, therein lies its beauty.
Like many others, I wanted a rifle that delivered benefits and features far exceeding its price tag. If you are one of them, you need look no further as I have certainly found it in the SMK TH208.
This time, the proof isn't in the pudding, it is in my dinner!

This is a Hunting Rifle that delivers performance far exceeding the asking price.

How to Calculate the Ballistic CoEfficient of your pellets.

As a follow on from my Self Reliant Airgunning - Pellet Production post , I thought I'd show a quick method on how I've been calculating BC without getting too technical.

The theory is pretty straightforward. I don't have two chrono's, just a combro, so I am relying on Chairgun and its 'BC based on POI difference' calculator.

Ten shots in total were fired. 5 at the zero of 12 yards, 5 at 30 yards. This gives us two distances. The fall of the shot will tell us how the pellet is performing in the barrel, then the air as it reaches its target. Of course, the chrono is telling us how fast it is leaving the muzzle.

Now, this is important. The database BC was very different from my findings. This is due to manufacturers taking an average performance figure, in the same way they take an average pellet weight and print it on the box. It's convenient and accurate enough for most peoples needs. Evidently, not mine!

When I was weighing the pellets I made, then a manufactured tin, I saw how we take so many figures for granted with out bothering to check and measure for ourselves. So no wonder we all have those 'mystery' shots that take us aback. Especially when changing pellet brand.

After the shots were fired, the average fps was taken (703.9 fps with a 10fps variation possibly due to a strip down just prior to the test) then the groups analysed and measured.



Accuracy on the bull would come later, for now, a clear grouping was sufficient. (I couldn't help but fiddle with the windage, though not elevation)

I settled for a rise of 0.896" over 18 yards. (click images to enlarge)



My old zero was 12.1 - 27.5 yards before the strip down and the RWS Supermags were calculated to be 0.0062 @ NTP already a big difference in performance (or calculations!)




Here we have the new zero and a graph that should accurately reflect the performance of my rifle and the pellet of choice. Chairgun will then update the pellet database for you with your BC calculation.

Yet another variable in airgunning to consider, measure and adapt to. Who said it was all 'point and shoot'?!

Dog Gun - Monday 02/05/11

Despite the forecast, no rain has fallen. The broad beans are yellowing and the ground is solid and cracked. No dawn patrol for me this morning. Last night and most of the day today was very windy. The strong squalls creating challenging shooting conditions and heightening the risk of wounding, not killing my quarry. So I had a lie in.
Late afternoon, whilst Emma and Fran were visiting the beach at Mwnt, I re-zeroed my rifle and sampled some of Nicks pellets. He had a mixture of RWS Superdome 14.4gr and Webley Accupells. These performed far better than the cheap SMK Spitfires I've been using. Decent pellets are around £10 for a tin of 500. My knock around Spitfires are £4. Great if like me, you just need to line the rifle's barrel and get it to 'settle in'.
With the Raider zeroed at 40 yards to the new pellets (Nick very kindly gifted me the tin!) I went off for my evening hunt. This time I saw two rabbits. I did everything by the book, even crawling to get as close as possible. And still missed. Afterwards I took a practice shot and found it was I, not the rifle at fault. I was too close. If I had correctly gauged the range, I would've known I'd have needed to aim a mil-dot down and not use the cross hairs. The rifle's accuracy was good and is improving rapidly with these quality pellets. So with practice and experience, hopefully my marksmanship will improve too.
I have chosen to view these situations and occurrences as lessons I have to learn, not as a success or failure. It is becoming quite clear that if I were to get dejected and negative then I may as well sell my rifle. Hunting is not easy. Walking slowly and quietly is easier and I am very much enjoying it. I try with each trip to recce somewhere new, and in so doing have discovered a few hidden and/or overlooked gems. The scenery is beautiful so whether or not the game bag is full, I always enjoy myself.
It's a bit like having a dog in that respect. An excuse to wander about aimlessly.
