Dialing it in
8 December 2025 06:28 pmOn my second range day with my new cyberpunk SARB-15 bullpup rifle, I realized a major flaw in my first outing in that I was attempting to sight my rifle optics with a red dot and reticle on a target with a red diamond at its center. This time, I switched to a green dot and that contract, plus a more stable sandbag setup, reduced my groups by about half. My six inch groups at 50 yards became three inch groups. Roughly.
But I was still unhappy with what I was seeing. I wanted some magnification to see the target better. The recommendation is to buy the scope for 80% of your shooting and the Vortex Optics Spitfire 1x Prism Scope was that, but switching out the range to 100 yards, I was having difficulty and could only imagine reaching out beyond that. I would not want to completely tank any shots out beyond 100 yards because my scope (and eyes) were only capable for that inner 80%.
Thus, I ordered a Monstrum Ghost G3 3X Micro Magnifier with Flip-to-Side Mount. They are supposedly designed to either sit in front of or behind the prisim optic to provide that magnification when you need it and flip out of the way when you don’t.
The third range day did not go well.
I tried the new magnifier after the prism optic and simply could not get it to work well. I think the second optic was adding a distortion so that I should, theoretically, sight it in through the magnifier but, once I moved it out of the way, the reticle wouldn’t line up anymore. I moved both optics so that the magnifier came first and it simply would not focus. The reticle was always either blurry or refracted. I moved back to the initial setup and, in the second attempt, could not make it work.
I returned the magnifier.
At the Liberal Gun Club annual convention, I had a chance to look through a Vortex Optics Spitfire 3x Prism Scope and I liked it. That was much of the reason I chose to get the Vortex 1x model. With that, I was looking at mid-ranges and though that, even at close range, the 3x wouldn’t be bad. So, I got one of those and put my 1x in a box for some future gun (perhaps a Ruger 10/22).
The fourth range day didn’t start out well. Sure, after mounting the scope I had used a laser bore sight at my workbench to try to line things up but the first shots at range went . . . somewhere. Not through the board. With the bore sight and the ballistics of the 5.56 NATO, I should have been off by a hand-span. Maybe even two. Who knows where those first rounds went.
I had brought my laser with me so went off the line to try to line things up again.
The next 5 round just barely hit the board, mostly centered but 22 inches high, but that was something I could work with. Adjusted, I pulled it down to 13 inches high. Then 5 inches high. Then just a little over half an inch low and a quarter inch to the left.
Nice.
According to the published ballistics and my optics setup, if I want to be zeroed at 100 yards (the reticle is calibrated for that) I should be an inch and three quarters low at 50 yards. I made some adjustments to try to get that and then took the rifle over to the 100 yard range and found it was printing about 2 inches high. I’ll do more math to try to work that discrepancy out but I may be better served by more testing at various ranges to work out the rifle’s actual performance.

This trip was about the 3x optic, though, and I was pleased. I could see at 50 yards very well and I wasn’t straining to see an 8 inch bullseye at 100 yards. And, also important, my group sizes had improved over what I had been doing with the 1x optic. My best groups were one inch at 50 yards and two inches at 100 yards (off the sandbag). Though most of my groups were bigger than that, they were still consistently half what I had been doing the week before.
When I was young and my eyes were good, I would spend my entire day and allowance at the Boy Scout summer camp rifle range. “One MOA all day long” with my grandfather’s Winchester Model 67. In the intervening four decades, however, I have not maintained that. Standard mil-spec expectation of the AR-15 is 4 MOA. That is (roughly) a four inch group at 100 yards. I am doing a little better than that but I am still far from the performance of my youth.
But also, the kind of shooting I am preparing for is different from the shooting I did then. Once I get the gun zeroed where I want it to be and am confidant in the machine’s performance, I am going to expand my manual of arms. Standing, kneeling, prone. Different ranges. Tactical movement. The Cabin Fever Challenge and Brutality-CQB East are going to be my benchmarks. I can make a two inch group off a sandbag at 100 yards, what if I was standing? Kneeling? After having just thrown a 35 pound kettle bell and run to where it landed?
That’s on me.

That’s on me.

When I was shooting 50 yards at first to sight in the scope, I used sight in targets with a red diamond and a 1 inch black grid. When I moved out to 100 yards, I also switched over to 8 inch black bullseye targets and my sight picture improved dramatically because (duh) I had been trying to sight a red dot scope on a red dot target. Only with that realization did I remember that my prism scope also has a green dot. That would have made my attempts to sight in the scope so much easier.
Out of about 250 round I had three feed jams. These jams left significant dimples in the brass. Online research returned, of course, a variety of diagnoses. One was that it was “definitely” the magazine. I have two mags and two of those jams happened on the same 5-round mag string. The third happened on the other mag later in the session. With only those, I don’t think it was the mag. Nor do I think it was the ammunition, two happened with the 5.56 NATO rounds and one with the 223 Remington ammo.
My groups at 100 yard were “on the paper” but that was only because I was shooting from a sandbag. Good enough for Brutality CQB where you are shooting at man-sized steel plates but certainly not “rifleman.” The Cabin Fever Challenge is generous with an 8 in target at 100 meters or 7 MOA but has one shooting standing, kneeling, prone, and sitting. Shooting offhand, my grouping would be even worse. But that’s part of the point of this whole endeavor, isn’t it. To do more shooting so that I can become a better shot.
The first bullpup firearm (that we know of) was heavy bench-rest target rifle manufactured around 1860 in London for a Professor Richard Potter. In 1866, William Joseph Curtis patented a repeating rifle design that sat on top of the shoulder. He also described using exhaust gas to cycle the action. There was the Thorneycroft carbine of 1901 and the French Faucon-Meunier semi-automatic rifle of 1918.

I did not attend any of the classes that were available (they cost more money) but the Old Guns class took place right next to the open range I was at, allowing me to look over shoulders at the assortment. The presenter had everything blackpowder from a handgonne up to cartridge guns (with, I think, the exception of a wheel lock). No one wanted to shoot the 75 cal matchlock, maybe they were intimidated by the caliber, so I stepped up to give it a go. Unlike many other guns that have a trigger sear and a spring where, once you put enough pressure on the trigger it fires (click, bang), this has a lever which, as you pull the lever moves the lit cord closer to the priming pan. I made the mistake of treating it like a trigger and I think doing that mashed the cord such that it didn’t ignite the powder. I had to try a couple of times more gently. The recoil wasn’t so bad. Yes, the big projectile means more recoil but blackpowder burns slower and with less pressure so the recoil impulse is more of a shove than a punch. Probably no worse than my Martini-Henry.
I got a chance to look through several versions of a holographic sight. That was a clean glowing reticle that showed no sign of the flaring I experienced with the laser.
The book itself is a smallish volume of under 200 pages and of a size that could easily be carried in a small satchel or even a large pocket. The brevity of such a small text suggests either that of a quick reference for more experienced hunters or a shallow overview, more for entertainment than utility. Each chapter consists of only 8 pages or so and focuses on a single species of dinosaur. After a general illustration, the author presents an anecdote of his (or a colleague’s) encounter with the specified creature. He then speaks to the regions where it is to be found and a few of its habits. There is then another illustration indicating where bone, lungs, heart, and brain are located and, thus, where the best place to apply a bullet to end the creature’s life quickly and efficiently. Finally, he details specific firearms and cartridges that he favors for the stopping power necessary to bring the encounter to its conclusion.





I first came across
Last week from 










Even before the “Age of the Cowboy” was ended by the railroad’s destruction of the need for cattle drives and open range (among other things), the romanticization of the cowboy way of life was thoroughly infused into the lore. As contemporaneous dime novels gave way to full novels, theatricals, and finally to film, the mythology of the cowboy and the cowboy way of life has only grown to mythical proportions.
