Walther’s new LGV Master Ultra .177 air rifle: Part 5
by Tom Gaylord, a.k.a. B.B. Pelletier
Today is the day many of you have been waiting for. I’ll scope the Walther LGV Master Ultra and test it for accuracy at 25 yards. I used the same Bushnell Banner 6-18X50 AO scope and BKL 260 1-piece high mount that I used on the Walther LGV Challenger in .22 caliber. The scope was already in the mount and ready to install. I thought about removing the sights; but since I couldn’t see them through the scope, I decided to leave them mounted.
One shot at 12 feet told me the scope was adjusted close enough to move back to 25 yards. The first shot at 25 yards then required some more adjustment, and I was ready to begin the test.
With the .22-caliber rifle, I rested the stock on the flat of my open palm with the heel of my hand touching the triggerguard. That gives the rifle a very muzzle-heavy balance and is usually the best way to hold a spring-piston air rifle. But not with this .177.
I had chosen to shoot 7.9-grain Crosman Premier lites as the first pellet because they showed so much promise at 25 yards with open sights. The .177-caliber LGV Master Ultra strung its first 10 shots vertically in a group that measured 0.67 inches between centers. While that isn’t bad, the group was vertical, which can be caused by either loose stock screws or by resting the stock on the off hand at the wrong place.
I checked the screws, and they all did require tightening; but when I shot a second group, it was vertical as well and slightly larger, at 0.819 inches. Obviously, loose stock screws were not causing the problem. Experience then told me to slide my off hand forward until I could feel the back of the cocking slot on my palm.
The second group of 10 Premier lites at 25 yards was also vertical and slightly bigger than the first. And this is after tightening the stock screws. It measures 0.819 inches across the widest centers.
Group 3 was the one I was looking for. Ten shots went into 0.326 inches at 25 yards. That’s 10 shots, not 5. Folks, that demonstrates what I thought was the case — the new Walther LGV is the TX200 of breakbarrel air rifles! Five shots in such a group might have a component of luck with it, but you don’t get lucky 10 times in a row. This rifle wants to put them all in the same place!
So, the best hold is with the off hand out forward, under the back of the cocking slot. That’s going to hold true for all of these Master Ultra models, I think.
Next I tried some H&N Field Target Trophy pellets because reader TwoTalon asked me to. I haven’t had good luck with FTT pellets in springers, but he likes them, though I learned that he’s shooting them only in a PCP. Still, I thought — what the heck?
Ten pellets went into a group that measured 0.683 inches between centers. While that’s not a bad group, it doesn’t look good next to the Premier lite group, so I won’t use it when I move out to 50 yards.
The third pellet I tried was the Beeman Devastator that did so well in the 25-yard open sight test. Again, they proved their superiority by putting 10 pellets into a 0.475-inch group. That’s pretty good for such an open-nosed hollowpoint. The LGV was hot!
JSB Exact Heavy
The last pellet I tested was the 10.34-grain JSB Exact heavy, which did okay in the open-sight test but with qualifications. What “qualifications” means is that I got 8 pellets in a tight group but had two unexplained fliers that opened the group considerably. This time, the results were even more bizarre.
With 10 shots, I got two extremely tight groups…one with 3 shots, and the other with 4 — and 3 wild fliers that don’t belong anywhere. The overall group measured 1.791 inches between centers of the two widest shots. I think what’s happening is that this pellet is very close to what this rifle wants, but it’s still far enough from perfection that it causes wild shots. These pellets fit the bore looser than the other three, which all seemed to fit about the same. The head size is a whopping 4.52mm, so put that into your head-size theories and see what you get. I just don’t know what’s happening, but it’s clear this isn’t a pellet for this rifle.
Wow — what happened? Four pellets went into the small hole at the bottom of the bull, another 3 went into the small hole at the top left and 3 pellets went off by themselves. Total group measures 1.791 inches across the two widest centers.
It’s clear the .177-caliber rifle is pickier about the pellets it likes than the .22, which seems to swallow everything. Find the right pellet, though, and the game is on! The best group with this rifle is roughly half the size of the best .22-caliber group at 25 yards. Fifty yards — here we come!
