Scotland : A Thrilling Encounter With Big Boy

 Morning is dawning the sun plays on the self seeded field of xxx pine. `I'm in the highest sheltered from the wind with my back to one block, a ride to my left and the fence line falling away infant of me. 

Ive seen the little Roebuck break cover and cross the ride a while back, but now only the wind in the trees, the creaking of the dead lower branches, and a terrible racket coming from behind me. The way the seat is it's not easy to turn around that far. 

Ahab is a notorious, and compulsive practical joker so my first thought is this is yet another of his practical jokes. The thrashing and cracking continues. Twisting my head there's defiantly something there.

There's only one stop where Ahab could possibly get out of the close-planted block, I'm not going to point even a de-cocked rifle at the spot. I'm just preparing a witty retort for when he steps out when a Red deer with a neck larger than my waist tears his antlers free of the branches and steps into the gully where the ride borders the trees. As I shoulder the rifle he hears something of my movement and spins 180 disappearing into the forest block. Never to been seen again. Easily one of the two biggest Reds Ive ever seen in Scotland 

Every dawn, and every dusk, for two or three hours a time  for the next five days I sit there. Not a sausage. 

Every day I stalk up the ride to glass the fence line, every day I find hooj deer turds, steaming a couple of times, big foot prints, but I never see him again. 

Should I have pointed my de-cocked rifle at the gap? No. Should I have sat still and waited? Of course. 

Hunting, not shopping.

Review: Heym SR30 Pt2

My Heym has been sitting at the back of the cabinet for a while. Not for lack of love. But I will admit some sentimentality has been creeping into my game.

Any shooting dad would like to gift a precision rifle to the offspring, but in their aluminium chassis' they're no heirloom. They have the accuracy but not the vibe. Picture the scene if you will.

Sometime in the future, hopefully a long time in the future. I've joined the choir invisible. It's the day after the wake, the b'tweeded ghillie (replete with splendid whiskers, smelling slightly of; Islay Malts, RS62, and mothballs) will stand solemnly by the fireplace, fighting back the tears, he cant very well hand a PRS rifle to James Bond my progeny with the words "This was your father's hunting rifle".  For that it's got to be wood and blued steel, so he can gruffly add 'an elegant weapon for a more civilised age'.

Elegant is as elegant does, you can keep your fine scroll work and your exhibition grade woodwork, the real elegance is simplicity, where less yields more. The SR30 is a stunningly simple straight pull action, probably the most elegant design yet, mine sits in a nimble Bavarian stock of modest 'expedition grade' timber.

Back in the mid 80's Peter Fortner was tying on a few cold ones with his friend Peter Angerer who had just taken gold in the Biathlon at the winter olympics.
Angerer lamented that the equipment available wasn't giving him much of an advantage over the Russians. Taking notes on a napkin, Fortner set about tilting the playing field in his friends favour.  Intending to design a faster action, by serendipity he also designed a stronger action.
The strongest possible shape is a sphere and here six of them are the lugs. You get an incredibly strong and precise, self-centring lock-up. So strong that Heym certify that the SR 30 has been tested by the Suhl proof house to 116,030 psi or 8,000 bar.
Wonder what that looks like? So did the guys at Norhunt.no


Using a .30-06 calculated according to Hartmut Brömels QuickLoadat 10,000 bar peak gas pressure the following experimental setup was used to fire a Heym SR30N straight-pull repeating rifle and the effects of this excess force photographed. Although the bolt did not withstand the force unharmed, even with this amount of force the bolt was not ejected to the back into the shooter’s face. 
Full story HERE.

My SR30 came preloved in .243 with a 1/10 twist and never liked 100gr bullets, at 23 inches the barrel is more hill-rifle than woodland-stalker. I washed a lot of copper out of it which helped, I considered chopping a couple of inches off the end but when I took a look though a borescope I abandoned hope. Time for a new barrel and a change of chambering to shoot lead free 6.5's. Since the Creedmoor craze/revolution of the last ten years shows no sign of abating, every gun shop now has new rifles so chambered, I'm confident that factory ammunition will be as ubiquitous as .308 and end up replacing .243.

Barrels and Baffles are like Tyres and Brakes, the more fun you have, the more frequently you have to replace them. 

I needed to engage the services of a gunsmith and buy a barrel. And there hangs a tale, a pretty sorry tale at that. For readers in The US of A. I know this next bit will stretch your credulity, but I promise you this all happened.
The greatest impediment to shooting sports in the UK isn't the government and the vegans, its the gun trade. From the importers, to people I know and consider friends, there's a surly malaise. Its literally as though they don't want your money. Everything is too much trouble.

Our slang term for gunsmith is Gun Plumber, the 'plumber' bit presumably inspired by their reluctance to answer the telephone, or on the rare occasion that they do, to give even the vaguest idea of when they might be able to 'fit you in'.

The obvious choice begrudgingly agreed that yes he could source a barrel for me from Heym, with a timeframe extending into, and possibly beyond, three months. His price?  Almost two thirds of the list price of a brand new SR30. Nothing like supporting the brand.

For 30% less the well-regarded F1 engineer, who specifies a high end stainless steel barrel, would take a look, I was welcome to visit, but no timeframe could be offered.

Top boy in the north was too pushed with his own builds, and suggested top boy in the south who is yet to return calls or emails.

A couple of other gunsmiths would, for only a little less cash, deign to allow me to join the long tail of their waiting list.

Sentimentalist that I am, this time I want my Heym to look like a Heym. If I was going to build an SR30 on a plastic stock I'd go with the stainless F1 guy or Top boy up north. I bought my SR30 because I wanted the Bavarian stock, it should have a german scope, ideally swing off mounts, and a blued barrel hammer forged from Krupps steel. As Heym intended.

Somewhat despondent I called a gun shop (in Scotland) where I've received excellent service before to see if they had a recommendation, and although not listed as a Heym stockist, the proprietor opened my eyes to a little known fact, (little known in the english speaking world anyway), Heym sell pre-fit barrels threaded and chambered for their rifles. Available within a fortnight and could be fitted and sent for proof immediately for ein kleines bisschen less than 50% of the original quote.
As simple as that.

Probably cursed it now, let's see how long it takes?

Unboxing Review: Heym SR30


Missing from the round up of European Sporting Rifles was the rifle I actually bought with my own money, the SR30 by Heym. Which in case you were wondering rhymes with rhyme.
Due to its inexplicable place far from the firmament of fashion this is; a handmade rifle you can still buy, preloved, for a lot less than the price of something plasticy and mass produced.

A by-word for old-school german engineering, Heym are famous for their; dangerous game rifles with stout Mauser actions. Their safari double rifles in calibers beginning with a 4 or a 5, and the SR21 a very nice iteration of the european sporting rifle theme, available in grades from 'working' to 'oligarch's heirloom'.
Just like at the office,  sometimes even the most conservative of characters can have an unexpected quirky side to them, so just because they could - Heym took the Fortner action of biathlon fame and scaled it up to centerfire dimensions. From the first time I saw one on a trip to that english institution  Holt's Auction I knew I'd get one later if not sooner.


The design does away with bolt lugs as we know them, or even Blaser's radial collets, and instead uses six ball bearings to lock up, making for an immensely strong straight pull action, that gives you a rapid second shot at that rampaging boar. The bearings might look diminutive, Heym have successfully tested the system at 110,000psi pressure, which is, give or take, double the 55,000psi pressure of a typical rifle cartridge.

Picture found online, I'm not taking my bolt apart, not sure I'd be a able to get it back together.

In Germany I'm told the rules state that you can't stalk with a cocked rifle, blocking the firing pin isn't safety enough, which lead to the de-cocking actions of several german brands. Here Heym excel themselves. As you push the bolt forward a seventh ball bearing on the side of the bolt snicks into place, acting on a shaft which pops the six radial bearings into their an indent, the rifle is now fully closed but still not cocked, slide the wooden-ball bolt handle that last few millimetres forward to arm the rifle.

 Pulled back - the ball bearings are fully retracted into the bolt
Pulled all the way back & under tension, with the bolt release disengaged - the bolt can slide free of the action.
 In the middle - closed but not hot
All the way forward- hot 'n' ready to rock

 The red and white tabs of the Cross Bolt system act as a second safety, allowing you to lock the action open or closed. When locked in the open position the bolt has absolutely minimal contact with the race way and can fall to closed under gravity.


Nice slim woodwork, rosewood snout on the fore end, bolt handle, and cap on the pistol grip. All checkering cut by hand.

Laminate, thumbhole (with or without adjustable cheekpiece), GRS Hunter, and a petite 'Dezima' are all factory options. I was on the verge of ordering a new stock but this one is an adjustable cheek piece away from ideal and I kind of like the fact that its got a few dings; I'm tough on stuff, and the first scratch I put on the new one would kill me.

Cold forged barrels, made in house, proven in competition everywhere north of Oberstdorf. My barrel dosen't seem to like PPU or 100gr bullets, 75gr it likes a lot more, but my start point for load development will be 68gr - if you've got anything meaningful to add leave a comment.

Heym's own trigger, super crisp at [a guess] not far beyond a kilo [2.2 lbs] with a single set-trigger function breaking a useful distance north of terrifying. I like the idea of set triggers more than the actuality. heym have gone for useful rather than 'keeps you regular'.

Please Note: The Suburban Bushwacker DOES NOT endorse the use of PPU brand ammunition.
