Fixed-Power Optics for F-Class — Testing in Competition

March 48x52mm High Master Scope — Tested in Competition

by Jay Christopherson, AccurateShooter.com Systems Admin
Using a fixed power scope on your F-Class rifle is not only effective, but can save you weight and money — key benefits when it comes to the F-Class game.

I recently tested the March High Master 48x52mm scope on my F-Open rifle in three different matches, including a Long Range Regional match in Montana and the recent 2017 US F-Class National Championships in Lodi, WI. While I’ve long been considering a fixed-power optic, it wasn’t until a recent F-TR build came in over-weight (with a large zoom scope), that I finally decided to give it a fixed-power comp scope a try. The March High Master 48x52mm saved me both weight (10.6 oz. or 300 grams) and money ($800+) compared to a top-end, variable-power March.

Across three matches and multiple conditions (including heavy mirage), I never found myself wishing that I had a variable-power scope on top of my rifle. And I never experienced issues holding rings on the target. A fixed-power scope might not be for everyone. However a serious F-Class shooter who needs to cut some weight, or save a little cash (compared to high-end zoom scope), shouldn’t be worried about being “under-glassed” with a fixed power scope such as the March HM 48x52mm. It can do the job. [Editor: Jay finished second overall in F-Open Division at the 2017 F-Class Nationals.]

The Case for A Fixed Power F-Class Optic

There’s been a thought bouncing around and growing in my head for the past few years while shooting F-Class — Why don’t more guys shoot a fixed power scope in F-Class? Nine out of ten F-Class shooters I’ve polled spend most of their time between 40 power and 50 power, regardless of the conditions. It seemed to me that a fixed power in the 40X – 50X range would be a great option.

I’ll admit, that I’ve long been an advocate of needing a variable-power scope so that I could “dial down to see the rings” on those really heavy mirage relays. There’s even been times when I’ve been successful dialing down to 35X – 25X just for that reason. But still, like most guys, I find that I rarely go above 50X and rarely below 40X – 99% of my time is spent right around 42X – 45X. Having gotten used to shooting high magnification now, it’s been quite a long time since I’ve bothered to dial down below 40X, even in very heavy mirage. But, I held on to that notion that it’s better to have it and not need it, than to need it and not have it.

I recently built an F-TR rifle. I made a slight mistake on the weight. Fully built with my zoom scope, the rig ended up at 8.3kg (8.25kg is the limit for F-TR). That’s not much overweight, but I don’t like to be too close to the limit anyhow. There are lots of ways I could have addressed the issue, but I started thinking again about the scope. I love my current variable-power scopes, but I couldn’t help thinking that a fixed power scope in the 40X – 50X range might solve my issue nicely (and give me a chance to try something new). So I obtained a March High Master 48x52mm fixed-power scope to test. The 48X magnification falls right into my comfort zone. With its 52MM objective, the March HM matched the profile of my existing variable-power scopes nicely. Aesthetics is at least part of the goal and in my opinion, 50MM+ objective scopes look “right” on F-Class rifles. It’s also worth noting that this is the only fixed power scope that I have tried so far and that I have no affiliation with the manufacturer.

There’s the notion out there that fixed power scopes have inherently brighter sight pictures or maybe “clarity” is a better word. This may be due to there being less complex lenses and fewer parts inside. I don’t have any way to quantify that, so I’ll just say that the image clarity is excellent on the 48X March. I also found that the scope weighed 300 grams less than my variable-power scope, which brought me under the F-TR weight limit nicely, as I had hoped.

Fixed-Power Scope at 2017 F-Class Nationals and Other Matches
Because my F-TR rifle was still in load development, I decided to try out the March HM 48x52mm at a couple matches on my F-Open rifle, while I waited on a part for my F-TR rifle. I fitted the 48x52mm scope to my F-Open rifle and used it at three matches: 1) a local 600-yard mid-range match in WA State; 2) the Long Range Regional at Deep Creek in Montana; and 3) the 2017 US F-Class Nationals in Lodi, WI. I ended up using it the entire match at all three matches. With three different matches, all a few weeks apart and in different parts of the country, I got a nice cross-section of light, weather, and mirage conditions to sample. At all three matches, and even in a medium-heavy mirage situation, I never found myself wishing I could dial down the power. In fact, I never thought about variable power at all — the scope was excellent in all of the different conditions. Even with a good deal of mirage present, I never had a problem making out the rings well enough to hold on. For what it’s worth, I used the scope while shooting on two different teams that set (pending) National LR and MR F-Open team records at those matches. If I didn’t have confidence in a fixed-power scope (and the March in particular), I would never have taken a chance shooting it where a team depended on me.

Scope Tracked Great and Click Values Were Right On
In terms of technical details, the scope tracked perfectly on my scope checker (there are several threads on the AccurateShooter forums regarding checking a scope for drift), which meant I felt comfortable using it at the F-Class Nationals. Critically, I spent a good bit of time working on the ocular focus (reticle focus) so that it would be perfectly set-up for my eye. I’ve found that many complaints about parallax and “soft” or “blurry” images can be traced back to the owner never taking this critical step with a new scope. Normally my scopes all have external, tactical-style turrets — the March HM 48×52 has covered turrets. I wondered how this would work for me, but again, I never thought about it while shooting. Once the covers are off, the clicks are extremely tactile and easy to read and it just never became an issue. The parallax adjustment works nicely and the scope tracked well with every adjustment I made, from 600 yards to 1000 yards.

What Could Be Improved
On the con side of things, I find the scale on the elevation turret to be a bit confusing. Most scopes I have used have an incrementing scale on the elevation (and windage) turrets, so that you can count up from zero as you dial up the adjustments. The 48X HM uses a ‘0’ that is centered on the turret travel (see photo above), so that you count down or up on the scale. Here, I would prefer a scale that bottoms out at zero (or that you can adjust to bottom out at zero) and then increments. I think it’s an easier and more consistent way to measure, but your mileage may vary. Other March scopes I’ve used have a color-coded system on the turrets which I also find a little less than useful. Again, I wouldn’t mind at all if March re-thought its system there.

The other con for me is the eye-relief. It’s middle of the road as far as other high-end scopes I’ve used, but for me personally, I still find it a bit on the short side — I would prefer more eye relief.

Save Hundreds Compared to a Premium Zoom Scope
On the plus side (from a cost standpoint), fixed power scopes are generally priced quite a bit lower than equivalent-quality, variable-power optics. The March HM 48x52mm (product # MAR1076) I tested is no exception. Bullets.com sells the HM 48x52mm for $1951.00. That’s $810 less than its variable-power relative, the March HM 10-60x52mm, priced at $2763.00. I consider the 48x52mm’s $1951 price to be very reasonable for such a quality piece of hardware.

Conclusion — High-Quality, Fixed-Power Scopes Are Worth Considering
Overall, if you find that you spend 99% of your time in the 40X – 50X range with your variable-power scope, I’d encourage you to give some thought to a fixed-power scope for F-Class. I’ve only tried one fixed-power optic — the March HM 48x52mm. But having used this excellent, fixed-power scope in several high-level F-Class competitions now, I’d have no qualms about recommending a high-grade, fixed-power optic to anyone shooting F-Class.
