Smog Testing the Marlin 17VS

My wife was 19 years old the day we were married, and I wasn’t much older – a mere 36 years ago. She’s little and Irish, both of which I believe have contributed to her: competitive spirit, auto racing trophies,  motorcycle license, three sons and an appreciation for firearms and shooting sports. Accordingly, asking her to go to an outdoor range on a cold blustery day, in mostly pouring down rain, to try out a new rifle was received as a welcome invitation. We loaded up the trunk of the car with a lot more stuff than we needed, and headed up to Los Altos Rod and Gun Club. It’s great to have a partner who shares your interests.
 
Background
 

I got to thinking about how I rarely shoot rimfire rifles anymore. While indoor ranges are plentiful, making rimfire rifles a good bet for convenient marksmanship practice, I’d really rather be outdoors shooting. Of course, once outside, and no longer restricted to rimfire, I’d have little cause to shoot them. The point is, for as much as I like the concept of cheap ammo and guns, my rimfire rifles are mostly dust collectors, awaiting opportunities to provide firearms education to grandchildren and other new shooters.

For a while, I thought I might like constructing a specialized gun based on the Ruger 10/22. However, after review, this seemed potentially a very costly project, that would yield a very limited application firearm. I thought a little bigger cartridge like a .22 Winchester Magnum might be a little less boring, I have owned a couple of firearms chambered for this cartridge, but they didn’t seem very accurate, and the ammo was expensive in light of the marginal improvement in performance over the hyper velocity .22 LR products. I really liked the concept of the 5MM Remington, but sometime between the morning of its introduction, and my afternoon arrival at a gun store, it apparently went obsolete. When the Hornady‘s .17 HMR was announced, and the product seemed to take legs, I followed the news and subsequent developments with interest.

I’m not going to cover the cartridge in detail, this has been done in many other places right down to full reports of early manufacturing delays, CCI’s production participation, the use of Hodgdon Lil’ Gun powder, etc, etc. I don’t believe any of that matters, other than in a distant future game of “Cartridge Trivial Pursuit”. Briefly, the .17 HMR is loaded with a 17 grain Hornady VMAX poly tipped and jacketed bullet, and the case approximates a .22 Winchester Magnum, necked down to .17 caliber. The Hornady box carries the notation “2550 fps”, however, I do not know what configuration of firearm this reflects, or under what circumstances the velocity was recorded. The 17 Hornady Magnum Rimfire is designed to shred small critters which, I suspect, it could do handily. When the number of rifle models chambered for the cartridge passed 10, and the number of manufacturers producing these models exceeded 7, even I knew it was time to jump on the proverbial .17 HMR band wagon.

 

Marlin 17 VS

It was my positive experience with Marlin’s  1885 Guide Gun, that caused me to take a good look at their 17 VS. Both gun’s are quite a departure from Marlin’s much earlier, more pedestrian, utility grade products.
 
The 17 VS MSRP is $346, however, the gun can routinely be found discounted by 10% ~ 20%. There is also a 17 V hardwood stocked, carbon steel model, that sells for approximately $100 less. Pretend there’s a gratuitous inclusion of a digital scale in the photo above; the VS weighed a hair under 8 lbs as received, 8 3/4 lbs by the time I got done hanging my junk on it; an Aetec scope with a large objective lens and a quality leather shooting sling. Yes, I know, the scope is too big for a rimfire, and I should have purchased a new nylon sling, because the leather variety will rot and fail in 40 years, no doubt while I’m hunting Peruvian chipmunks in a distant jungle setting, thereby allowing the unchecked little buggers to overwhelm and gnaw me to death.
 
The gun’s trigger pull, as received, but after general cleaning was 4 1/2 lbs and crisp. The overall length of the gun is about 41 1/4″, the stock pull is a comfortable 13 3/4″, the forearm bottom is formed flat, about 1 1/2″ wide. The heavy 22″ barrel has a 1:9 twist, and four groove rifling, rather than Marlin proprietary Micro-Groove® rifling. The barrel has a target crown with a .815″ muzzle. The gun does not have metallic sights, however, the receiver has a 3/8″ groove to accommodate scope mounts. With scope in place, the gun’s CG is right at the union of the barrel and receiver, making the gun very easy to hold steady on target from an offhand position.
 

Parts of the gun are stainless steel; barrel, receiver, front breech bolt, striker knob, and trigger stud. Some parts are nickel plated carbon steel; bolt handle, clip and sling swivels. The trigger guard is a silver finished cast alloy part, as is the trigger. The stock is a nicely finished hardwood gray/black laminate, capped with a non-slip recoil pad.

The gun’s fit and finish is excellent; not a scratch, rough edge or blemish anywhere, which is a departure from most everything I have recently purchase. Nice to see this quality from Marlin.

 
The 17VS is packaged with a set of Weaver combination mount/rings designed to the rifle’s 3/8″ groove receiver. The mount’s packaging carried the description “1” Tip Off See-Thru Mounts”, however, the aluminum and nickel plated steel assembles neither tip off, nor can they be see through, unless of course the scope isn’t installed, which seems to run counter to the intent of the assemblies. The front mount saddle is .445″ above the barrel surface. Adding the radius of a 1″ scope tube provides clearance for an approximately 1.9″ scope objective bell, meaning 40mm objective scopes should clear without a problem. Marlin packaged a useful set up, I just felt the gun had greater potential, and wanted to fit a scope appropriate for use over greater distances, and in conjunction with smaller targets.
 
 
I picked up a set of Kwik-Site adapters from Cabela’s, along with a set of high Weaver rings – the adapters permit any gun with 3/8″ grooved receiver to use conventional Weaver type rings. The top surface of the adapters were .700″ off the barrel, the ring saddles were another .300″ for a total sky scraper height of 1.000″. Adding in the distance of the radius of the 1″ scope tube, allowed for a total scope objective bell radius of 1.500″.
 
The Simmons 3.8~12x Aetec scope, with its 2.45″ bell, mounted with half inch clearance over the barrel; enough room for parallax adjustment, without the scope looking too oddly mounted. The set up was very solid, with each component substantially locked in place.

I thought I was all set, when I remembered you can never shoot a new caliber gun without incurring some peripheral expenses. In this case: a Dewey Mfg. Nylon coated cleaning rod, a jag, a patch loop and a bronze brush. It’s hard to envision how small a .17 bore is until you put a patch loop down next to a .22 LR loop (bottom), or buy an air rifle, which ever comes first. These small accessories may be a little hard to locate, but Brownells had them in stock and shipped them the same day they were ordered.
Fortunately, my old Simmons Boresight kit included a .17 cal stud. The scope, with H/V adjusted to mid range, was initially positioned a little higher than I liked, but not seriously out of adjustment range center.

 
The 17 VS at the range…in the fog…in the rain

Lately, I haven’t had free time to spend on a near 3 hours round trip to the usual range, so I tried  the “Where to Shoot” web site, and located several alternative area ranges. Based on their informative web site, the expansive services offered, and the courtesy and expediency of responding to e-mail, I decided to try Los Altos Rod and Gun Club. As the view through the windshield suggests, we might have picked a better day to try a new facility, but they had a full staff and all services were available, so….
I believe my wife’s vertical hairdo worked well as an accurate indicator of wind velocity. However, while she was able to report 10 knots and gusting, she did not share my appreciation for this good fortune, and demonstrated her sentiments by shooting consistently better groups. Diane was comfortable with the rifle, although the stock pull was a bit long and her cold weather bulky coat kept getting in the way. Session punctuating periods of near horizontal rain led to conversations regarding a design for eyeglass windshield wipers.

 
We shot at 50 yards, and 100 yards when target visibility permitted. We recorded velocity, particularly early on, when the rain subsided enough to allow the chronograph sky screens to function properly. Chrony generally seemed not intimidated by the bad weather as it chugged out data consistently, once I moved the line of fire a bit closer to the sensors. As the only shooters on this particular range, we pretty much had the safe run of the place under the supervision of a range official in the tower. Just not having to work to 15 shooting period constraints was a big help, as we could start and stop, and change targets whenever appropriate, without concern for other shooters.
 

This made setting up a chronograph, scheduling shooting sequences and changing targets easy for a change without the typical 15 minute shooting increments, followed by a group cease fire for target changes .

Los Altos did a great job on field drainage as, even in this miserable weather, there was no sloshing around when changing targets, or 20 lbs of mud on boots. The cement firing line pad extended far enough forward to place the chronograph tripod on the hard level surface.

 
First 16 shots – FPS
1 2557 6 2564 11 2594
2 2565 7 2584 12 2594
3 2569 8 2579 13 2598
4 2585 9 2606 14 2597
5 2587 10 2598 15 2602
 
The velocity, even from a new bore, was as advertised. I’m sure a little more use will smooth some of the lumps and rough spots out of the bore, but the velocity is there. The gun is quiet, the report is more of a pop, and it’s easy to keep eyes open to watch the target. The only difficulties I encountered were the lack of eye relief latitude in the Aetec scope when set to top magnification, and the Weaver mounts I installed were too high for the stock comb to provide proper face support when shooting from the bench. The stock’s comb is about 1.5″ below bore centerline, which means the mount/ring combination packaged with the rifle would be near perfect with almost any scope with a 40MM objective.
 

I didn’t waste a lot of time zeroing in, I just wanted to get close and see how the cartridge and rifle would group. The first target, top left, was a 14 shot (2 clips full) 50 yard warm up. The group was under 1/2″, which I thought was pretty good for that little bullet: in gusting winds, with my general lack of target shooting skill, and my lack of familiarization with a new gun. My wife shot the same size group, perhaps a bit smaller, immediately afterward.

The middle target is two 50 yard 5 shot groups, each is less than 3/8″, shot after approximately 25 rounds had passed through the bore. I shot the first, then shifted the gun in the rest a bit and shot the second set. The gun was able to group this well routinely, and barrel temp didn’t seem to matter very much. I actually shot with the forearm on the rest for the first group, and with the barrel laying on the rest with the second group. I don’t believe point of impact moved as a result of pressure on the barrel, but rather me moving the rifle in the rest.

The last target is 5 shots at 100 yards. It is less than half an inch and not very unique in terms of the rifle’s performance. This group was shot after the rifle has seen perhaps 50 rounds. No sign of accuracy or grouping fall off as a result of bore fouling materialized the whole day. For some reason, I thought the little .17 bore would load up with copper and I’d start seeing flyers and tumblers but, as I indicated, this was not the case.

 
Summary
 
Great combination and lots of cost effective shooting fun. I think it is great that Hornady and their cartridge gun producing project partners made this effort. The Marlin is a well made rifle, the cartridge is a great performer and it will see a lot of use on small game and varmints. I can’t wait to get mine back to Maine where the gun can be put to a more practical test.
 
Thanks
