Writing as B.B. Pelletier
This report covers:
• Velocity with Crosman Premier lite pellets
• H&N Baracuda Match pellets
• Air Arms Falcon pellets
• Firing behavior
• Cocking effort
Okay, sports fans, today we’ll test the new .177-caliber Walther LGU underlever rifle for velocity. And there are a couple other things we’ll look at.
Velocity with Crosman Premier lite pellets
Getting right to the task, I first shot the rifle twice to warm up the action. Then, I loaded a 7.9-grain Crosman Premier lite pellet and started the clock. The velocity started out in the 870-880 region, but on shot 7 it dropped to 842 f.p.s. The high for this string was 888, and the low was 842 f.p.s. That’s a spread of 46 f.p.s. that I think is due to the newness of the rifle. After it gets broken in I think it will settle down to a spread in the 20s or less.
The average with Premier lites was 872 f.p.s. That means this pellet developed an average muzzle energy of 13.34 foot pounds.
H&N Baracuda Match pellets
H&N Baracuda Match pellets went almost 100 f.p.s. slower, averaging 777 f.p.s from the LGU. You would expect that, given the pellet’s greater weight.
The spread ranged from a low of 770 to a high of 786 f.p.s., so right there the first pellet’s spread was cut by more than half! At the average velocity Baracuda Match pellets produced 14.28 foot-pounds of energy. That’s surprising, because usually a springer is less powerful with heavier pellets. It alerts me to the fact that this rifle might have some differences. The head size of these pellets is 4.50mm.
Air Arms Falcon pellets
The final pellet I tested in the LGU was the Falcon from Air Arms. Because this domed pellets weighs 7.33 grains, I expected it to be faster than the Premier lite that weighs 7.9 grains and the Baracuda Match that weighs 10.65 grains. While they were faster than the Baracudas, they were the same velocity as the Premiers. I also noticed they loaded very easily, which means they are a little small for the LGU’s breech.
Falcons went an average 872 f.p.s. with a spread from 864 to 882 f.p.s. Even though the average was the same as for the Premiers, the spread with Falcons was just 18 f.p.s., compared to 46 f.p.s. for the Premiers. That shows the gun is already starting to settle down. At the average velocity, Falcons produced 12.38 foot-pounds of energy at the muzzle.
Given that Baracudas were the most powerful in the LGU and these Falcons were no faster than the heavier Premiers, I will have to watch this rifle during the next set of tests. The powerplant is not behaving as I expected.
This test was the first time I really had a chance to feel how the LGU feels when fired. I can feel a small buzz on every shot; and with the Baracudas, the buzz is a little more prominent. It’s one of those things that isn’t objectionable, but it’s there.
The LGU cocks smoothly without any hesitation in the lever’s movement. But on the scale I did see one place in the lever’s arc where the effort spiked up one pound. On average, the effort is 37 lbs., except for that one spot where it spiked to 38 lbs. I get the feeling the effort will decrease by a couple pounds after break-in.
As the rifle came from the box, the 2-stage trigger was set to release at 1 lb., 15.5 oz. (31.5 oz). I liked the length of the first stage, which is long; but knowing that this is an adjustable trigger, I got out the tools and made some adjustments.
As it turned out, the trigger came set to the lightest pull. After I attempted (unsuccessfully) to adjust it lighter, the pull measured 2 lbs., 1 oz. The first-stage travel was also set to the lowest limit. I did adjust it longer, which worked as the instructions said.
I think you’re going to like the trigger right out of the box. There’s just a slight hint of creep in stage 2, but it’s very slight. It might go away after break-in; but if it doesn’t, perhaps a lubrication would do the trick.
Evaluation so far
I still like the LGU at this point. It feels very TX-like, and the velocity is about were it should be. I’m really looking forward to mounting a scope and seeing what this rifle can do at 25 yards. That’s next.
