Ok, before I start I want to make it clear that this is not a "apples to apples" test, it is meant to be quite the opposite. We all know a $3500 piece of glass will perform better than a $1400 one, but how much better? I have owned and tested many optics over the years from USO to S&B to Premier to Leupold to you name it, but what does one do if they want what the "big boys" use but don't have a 3K plus optics budget? Here is where this story started.

I ran Premier Heritage optics for the last few years, recently switching back to a S&B 5-25 P4f on my primary tactical match rifle for this season. Late last year I had a situation that required running a optic that was loaned to me, a Bushnell 3.5-21 G2DMR. I had no time with this optic before a 2 day tactical match, literally mounted it up the morning of the match, zeroed it, signed in and started sending rounds down range. My first impression of the Bushnell was more of a "why the hell don't I run these", or sell the S&B and buy 2 DMRs and have cash left over for that mater?

So, now to the optics; test optic #1 is a S&B 5-25 P4f CCW with DT turrets, and test optic #2 the Bushnell 3.5-21 G2DMR. First thing you will notice about the Bushnell next to the S&B is how compact it is, 13.2" long vs the 15.5" for the S&B. The S&B looks like a stretched limo next to the Bushnell, but we are also talking about a 25x optic vs 21, as well as a 56mm objective vs a 50mm which will effect performance, I'll touch on that in a minute. Both the Bushnell and S&B run the stout 34mm tubes, side focus, and FFP mil based reticles, features that are a must for me in the world of tactical match shooting, with the exception of tube diameter. The S&B comes in at 32oz, the Bushnell at 32.5oz, so we are at a tie on weight despite the Bushnell's more compact size. One of the many nice features about the S&B with CCW elevation turrets, all of the controls are CCW, from the magnification to the focus to the turret, this is a nice feature and it becomes very intuitive to operate when the pressures on. The S&Bs DT turret offers a massive 14 mils on the first rev, with a total of 26 mils if your base allows, with zero stops. My test rifle has a integral 20 MOA base, I am only able to utilize about 19.2 mils before it runs out of adjustment, plenty for the 243. To be able to utilize all 26 mils of the S&B your rig will most likely require a 40 MOA base. The Bushnell's biggest Achilles heel is its lack of elevation, 5 mils per rev and no zero stop, better count your turns and reset to zero when you get off the line. The Bushnell offers a very nice locking turret design, pull it up and turn, push down to lock, very easy. The Bushnell has fairly solid clicks, but seem fairly vague and mushy compared to the S&B, but you always know where you are. Both the S&B and the Bushnell passed a rigorous box test with no issues, tracking was spot on for both optics well out past 1K yards. Both optics offer a marked side focus, numbers and actual focus distance seem to be spot on for both the Bushnell and S&B. Both optics have similar eye relief, 3.7" for the S&B and 3.75" for the Bushnell, so they would both be well suited for heavy recoiling rifles.

Now on to the glass; is there any question who the winner is here? Its the S&B, and by a margin. Glass on the S&B is astounding, color and clarity are hard to match, as well as the S&Bs low light performance, this is where the 56mm objective pays off. Even on 25x, the S&B is bright with a very forgiving eyebox. A testament to Bushnell, the glass is good, even sitting behind the Bushnell for a solid day of shooting you come off the optic with no eye fatigue. Color is better than average on the Bushnell, optics are very clear, as good as many other high dollar and mid priced scopes I have owned. The Bushnell does tend to get very dark above 19x, I would consider it a 3.5-19x because it is nearly unusable above that, eyebox gets very small and that coupled with the darkness makes spotting impact very difficult above 19x. One annoying feature of the S&B is how the optic "tunnels" when magnification is adjusted below 8x, about 7.5x and down it becomes very noticeable, the Bushnell will start to tunnel around 4.5x, which is isn't much of an issue. Glass quality seems to be a big debate in tactical optics, but I feel it is not the deciding factor in deciding a scope, there are many other features that should be considered far more important.

Reticles; I am a huge fan of the Bushnell's G2DMR reticle, it is a very well thought out mil based reticle, fine enough for small targets, .5 mil hash marks and even breaks down to .2 on the outside of the vertical and horizontal, great for ranging. The fine outer hash marks actually give the appearance of a duplex style reticle on low magnification which helps considerably. The G2DMR also offers the mil "tree" for windage and elevation holds. I dial for elevation and hold wind and don't find the tree feature very useful, but it does come in handy when engaging multiple targets at varying distance if you don't have time to dial. Now to the P4F reticle of the S&B, this is the 2nd S&B I own with the P4F and I think it could use .5 mil hashes in the intersection of the reticle, vs the 1 full mil center. The S&B also offers .5 mil hash marks and has .2 mil breakdown for a full mil on the outsides of the reticle. Illumination, your not going to get it with the Bushnell, S&B does offer a 10 position rheostat, which in all honesty I have only used a few times for night stages, but it wasn't a game changer.

So what's my take after going from S&B to Bushnell and back again? Simple, if you can afford the S&B, buy it, if you cant I would run the Bushnell and not think twice. The reality is the S&B won't make you shoot any better or help you win matches. As long as you can count your revs and don't get lost with the Bushnell, you can be just as competitive with either optic. Bushnell now offers a 10 mil version but it will run you an additional $550, so now your in the $2K range of optics, but the Bushnell can still hold its own at that price point.

A few pics, I will replace the reticle pics with ones at the range, when my camera is charged...

Nice read with my morning coffee....Thank's....I run the HDMR with the H59 and enjoy it very much. I don't have to be fast on the knobs so the zero stop ( or lack of ) is not an issue. One day I hope to be behind a S&B....
 
11-position illumination rheostat standard

...S&B does offer a 10 position rheostat, which in all honesty I have only used a few times for night stages, but it wasn't a game changer.

Excellent informative, un-biased, and concise write-up, Captain Kirk. I'm just going to clarify something: An 11-position illumination rheostat is standard on ALL PMII 5-25X[56]s' (the phrase “...S&B does offer a 10 position rheostat” suggests two things: (a) illumination is an optional feature on the PMII 5-25X[56], and (b) that this non-existent illumination option is 10-position.

I don't know how many people actually use illumination, but I think clarification of the PMII's illumination rheostat is warranted for those considering one. Again, excellent, informative, un-biased, and concise write-up.

To clarify, you say that the Bushie's Achilles Heel is its lack of elevation; I suspect you ware talking about the turret being 5 mil/rev and no zero stop, and not the amount of travel, as the erector assembly in the DMR has more travel inside the scope tube (34.5 mils) than the S&B (31 mils, I measured mine). The knob on the DMR does not limit the travel so the DMR can actually have more elevation available than the S&B when paired with a base or mount with a lot of cant; the S&B will never have more than 26.5. For most people neither would be a limiting factor, just sayin' is all.

Also, I've handled or own (still own) 3 different DMRs and I don't know where the description of "mushy" with regards to the turrets comes from; the individual clicks are very distinct and well defined. There is a small amount of give either side of the click that is a by product of the sliding knob locking feature, but I would never describe the turrets as mushy. One would never mistake what click they are on with the 5 mil/rev DMR.

Your correct Joe, 5 mils "per rev" but it has tons of adjustment, my reference was more to needing to count how many revolutions you are into the elevation vs total travel. As far as the click detents, they feel slightly mushy next to the S&B and it is due t the locking turret cap as you described, but as I mentioned you always know where you are. I'd go as far as to say the Bushnell turrets feel very positive and tactile compared to many other optics, especially ones in its price range. I have gotten used to the Premier Heritage and S&B turrets, which have very precise detents in the turrets, more of a "chunk" than a click.

I think its fair to say the 5 mils per rev is the Bushnell's biggest Achilles heel. I am happy with nearly every feature of the DMR with the exception of the 5 mils per rev, but I could deal with it, and have.

I also have an XRS with 10 mil/rev and the play in the turret knob is the same as in the DMR.
Coupled with an angular distance between clicks half that of the DMR, the XRS (and I'm sure the ERS) can be a little vague about which click you're visibly on. The clicks themselves are quite good, though, if you count clicks.

I liked your write up.

There's no perfect scope out there but the S&B was the only scope on the market which came close to having most of the features I wanted. Those features were... 10Y parallax, H-59, illume, at least 10 mils per turn, ZS and superior optics.

FFP scopes...I started out with a Horus Predator 8-26x50, then got a USO with a H-25, then a NF F1/ H-58, then some HDMR/ H59's and have finally worked my way up to S&B/H59. Almost $4000 a pop is kinda ridiculous for a riflescope so I doubt I'll buy another but I never know what I'll do next so who knows???, LOL. I'll say this, S$B does have a high level of refinement to it and is a pleasure to look through.

I've been switching it over from the 6x47L and trying it on my Field target air rifle with great success. Using the SHOOTER ballistic program for dope and drift just like at the centerfire matches has helped a lot in figuring out the wind holds. Loving this scope !!!

The HDMR is good basic scope with few faults. I was glad they put 10 mil knobs and ZS on the newer version, hopefully they did a good job. 10 mil knobs can turn into a big flop real quick if they don't index well and don't have distinct clicks. Both the HS F1 and March 3-24 turned out well.

Scope manufactures, please design 10Y parallax into your scopes!
 
Nice writeup! From someone who's only seen this comparison from the S&B side and who really likes the G2DMR reticle I appreciate the info. The only problem is that I've become so spoiled with the whole I never have to worry about not being on the right revolution I'd hate to give that up. I think that Vortex Razor HD's might be worth a look too.

Nice review Captain Kirk, thank you. I love my Bushnells, I have the earlier one like you have without the zero stop and 5 mils of ev but also bought two more of the newer ones, ERS 3.5 -21 and a 4.5-30. The G2DMR is just great and like you stated, they box test without any problems. I also like the knobs, some have said they were too big but I like the no bs way they work and feel. Pretty amazing scope for the money or even for more money. I like mine much better than my Leupold MK 4s.
 
Great review and write up Cap'n Kirk. I have both a Premier 5x25-56 and a Bushnell HDMR/H59. I'm a huge fan of the HDMR and completely agree that it's an outstanding value at its price point. I love the S&B's except I'm not ready to spend the money on one until I can spend more time behind either the PF4 or MSR reticles to if I'll like either one.
