You have waited patiently for this 50-yard accuracy report since the middle of May. I have had the rifle to the range several times, and today I’ll tell you what happened.
The first time I went out, I couldn’t get the rifle to group with any pellet. No matter what I did with the power level, the pellets went all over the place. The groups were 5 to 7 inches. After seeing what the rifle could do at 25 yards with the same pellets, I knew something was wrong, and I thought I knew what it was.
I removed the muzzle cap and found the problem. The cap has a bright line down the inside. Pellets have been scraping the inside of the cap before they leave the muzzle.
The next time I was out at the 50-yard range, the wind was gusting to 20 miles per hour. I shot several groups with the muzzle cap removed, but they didn’t do any better than 2 inches. I didn’t want to report that because of the wind, so a third test was required.
Last Friday was the third and final test for the Kral Puncher Pro pcp rifle. The wind was as close to zero as it gets. I shot with the rifle rested on a sandbag. So, the conditions were perfect.
I shot at full power because this was a 50-yard test. I knew the rifle likes to be filled to 2900 psi (exactly 200 bar) and that is where it was filled. The muzzle cap was off the rifle and the report was a little louder, but not by much.
Ten RWS Superdomes went into a group that measured 5.263-inches between centers. This was clearly not the right pellet for 50 yards. At 25 yards 10 of the same pellet had gone into 0.615-inches, which made this group all the more surprising. I won’t bother to show a picture of it.
JSB Exact Jumbo Heavy
Next to be tried were 10 JSB Exact Jumbo Heavys. They landed just below the bull I was aiming at in a 1.436-inch group. This was more like it, though not as tight as I had hoped.
Adjust the scope
At 25 yards the Kral had put 10 into 0.728-inches, so again I was surprised by the lack of accuracy at 50 yards. However, I adjusted the scope to hit higher and tried a second group of Jumbo Heavys. This group measures 2.284-inches between centers. This group is very vertical which led me to believe the rifle needed to be filled.
This was going the wrong way, so I decided to try a different pellet. When I checked the onboard pressure gauge it told me the rifle still had 2500 psi, which is the middle of the charge, so I shot one more group. This one was with a different pellet.
JSB Exact Jumbo
In the 25-yard test the JSB Exact Jumbo pellet had been the most accurate, putting 10 into 0.492-inches. I felt that should translate to less than an inch at 50 yards, so I tried it. The rifle was still shooting on high power and was in the middle of a fill.
Ten pellets went into 0.944-inches. Hurrah! The rifle is accurate, after all.
I now filled the rifle, since 40 shots had been fired on high power. I dialed the power back just a little and tried the JSB Jumbos again. This time the group was lower and more open. Ten pellets went into 1.919-inches at 50 yards. That’s going the wrong way again, so I decided to try a different pellet
H&N Baracuda Match 5.53mm heads
Leaving the power where it was (just under max) and the scope as it was adjusted, I shot 10 H&N Baracuda Match with 5.53mm heads at 50 yards. Ten went into 2.633-inches at 50 yards. Another pellets that’s not for this Kral.
I am not impressed with this Kral Puncher Pro. It does handle air well, and the walnut stock is very attractive. However, the trigger is too heavy and I had to do too much to get one good group at 50 yards.
There may be something wrong with this particular rifle, because the 50-yard groups are so different from those shot at 25 yards. I did find that the muzzle cap was touching pellets as they left the barrel; maybe some of the baffles are, too.
I’m not giving up on Kral PCPs, because they do offer a lot of value at a low price. I have a bullpup to test next. It’s called the Puncher Breaker (where do they come up with these names?) that’s also in .22.
