It's not that we can definitively say it won't (because we can't). It's merely that our experience tells us that this is extremely improbable. The point here is that his gun MAY WELL be one in a thousand factory guns that actually do this; they ACTUALLY DO EXIST. But, if I owned one, I would not include that statement in a website contribution where I wanted people to take everything else I said as reliable information. When I see it (or similar statements), my view of everything else along with it comes under much greater scrutiny. In this case, I found all else in his posting to be right on the money. Perhaps his gun is too."
And:
2) " Now: as to my comment about the ammo. I am deeply embroiled in my very first .17HMR experience. The rifle was a Christmas gift, so I feel a great obligation to make it work. Since I got the gun at no expense, I felt free to invest expense where necessary. It is a Savage 9317BTVSS (Lam Thumb Stainless). The gun wants to shoot well. The ammo will not allow it. I have tried each and every brand and all bullet weights.
Now: admittedly, perhaps my criteria is a bit more demanding than most. Sandman claims near-half inch groups at 100 yards. All my partners made the same claims. Just last week, all five of us were here at my range. 100 yards, hard bench inside my heated,insulated shooting cabin, Caldwell Rock Tripod, eared sandbags front and rear. Five shooters, six rifles (one guy has two). One is a Marlin, all the rest Savages, all fat-barrels. Seven different types of ammo at our disposal. The rubber hit the road, and no alibis. The result? Five shot groups to a half-inch square target averaged about 1.25" overall with ammo that each gun showed a preference for.
This is precisely the result that I obtained during my sessions shooting alone with my gun. Then I invested money in a thicker base plate (Savage uses sheet steel, which allows the bedding screw to buckle the metal). Then I installed a Rifle Basix trigger, getting the pull to 1.25lbs (Accutrigger's bottom limit is 2.6lbs). Then I did the most meticulous glass and pillar bed job I've ever undertaken in 40 years.
All this investment and time into the gun, and yes, I can claim "I get 1/2 inch groups". Because I got two of them. Out of 50 plus.
The gun will cluster three or four, but out of a group of five, at least one, and usually two stray from the flock. The chronograph was the tattle-tale (as it usually is). The rounds that stray are almost invariably an anomaly of velocity as well. This is the basis for my statement about ammunition quality.
Rumors abound that Hornady and CCI load all the cartridges for everybody (Rem,Win,Federal, etc.) This may be so, but my gun prefers the Remington and Winchester offerings markedly over the CCI, Hornady,Federal, etc. The black sheep (sorry, Ablaut) was Federal. 2-3" groups out of every one of these rifles we shot. Typically, each individual gun will like something different, and perhaps Ablout's gun has a taste that these didn't.
Now, with rimfire ammo this is not unusual, and in fact it is the norm. Only the .22lr has been blessed with manufacturers efforts (and a customer base willing to pay extra) to construct match-grade ammo. And with stellar results. The difference between high-dollar target grade .22's and cheapie bulk .22's on paper is the difference between night and day. I am a firm believer that the .17HMR market would support the development of match-grade ammo. Perhaps I am wrong. Perhaps the huge number of .17HMR shooters are very happy with "hitting an ammo box at 200 yards" sometime during the course of a 10-round clip. Certainly nothing wrong with that."
And, as for 1/2 MOA (this is 1" or better groups) at 200 yards "all weekend long" again, I will repeat this:
It's not that we can definitively say it won't (because we can't). It's merely that our experience tells us that this is extremely improbable.
