Today we look at the Benjamin 392 that has been resealed. The first report was done on the gun as it came from the pawn shop. All I did was oil the pump head with ATF Sealant and then test the gun. It’s been a long time since Part 1, so you may want to read it again. In the last test I said this was the fastest 392 I have ever tested.

The rifle responded well to ATF Sealant. I will run those number with today’s test figures for comparison.

The rebuild

I sent the gun to reader Jeff Cloud for a rebuild. He is the guy who rebuilt my Sheridan Blue Streak a couple years ago. read more


Beeman R9 with Vortek center-latching air piston: Part 2

Part 1

This report covers:

  • Today’s fill
  • JSB Exact
  • Predator Polymag
  • H&N Field Target Trophy
  • H&N Baracuda
  • Crosman Premiers
  • Benjamin Cylindricals
  • Cocking effort
  • Trigger pull
  • Firing behavior
  • Summary

Today is velocity day for the Beeman R9 with the Vortek center-latching gas piston that I’m calling the center latching unit (CLU). Bear in mind as you read today’s test, that this unit allows the owner to adjust the pressure inside the gas piston — raising or lowering the velocity and cocking effort. So, this is the first of several tests of the unit.

Today’s fill

I filled the CLU to 675 psi when I installed it. So that’s how it’s set up today. I will test it with 6 different .20 caliber pellets — one more than Pyramyd Air carries, if you don’t count the felt Beeman cleaning pellets. Let’s get started. read more

  • H&N Baracuda Match
  • Other pellets
  • Experience

  • Summary

Today we start our look at the accuracy of Gamo’s Urban PCP. Fasten your seatbelts, guys, because today will be a bumpy ride!

Scoped

I mounted a 4-16X50 Leapers scope that is obsolete, and is unlike any scope they make today. But 4-16 power is the key.

Knowing the Urban’s performance curve, I filled to 3000 psi and shot 20 shots before refilling. There are 25 available at this pressure, but I was shooting 10-shot groups, so 20 was the limit.

The test

I shot the Urban off a sandbag rest with the rear of the butt rested for extra stability. The range was 25 yards.

Sight-in

The first shot hit the target from 12 feet about 1.5 inches below the aim point, and centered on the target, so I moved back to 25 yards and resumed sight-in. In 5 shots the rifle was zeroed, and I sighted the first pellet a little high to preserve my aim point. read more

This report covers:

  • All tests
  • Does the POI shift with the reservoir pressure?
  • Fill the rifle
  • Bolt probe in the way
  • Second group
  • Second experiment
  • Experiment three
  • Bumped the barrel
  • Don’t bump!
  • Next

I told you I was going to test the heck out of the Umarex Gauntlet and I’m doing it! Today I’m shooting at 25 yards to test three things readers wanted to know about the rifle. Well, maybe I wanted to know them, too.

All tests

I’m shooting from 25 yards off a bench with a sandbag rest in front and a padded rest under the butt. The rifle is as still as I can hold it. All shooting is done single shot.

Does the POI shift with the reservoir pressure?

First I will test to see if a change in reservoir pressure changes the point of impact (POI). This is fairly common in PCPs, so we shouldn’t be surprised if it does shift. read more

This report covers:

  • JSB Exact Heavy
  • H&N Baracuda Match with 4.50mm heads
  • Decision time
  • Crosman Premier 10.5-grain heavies
  • Another decision
  • JSB Exact Heavies
  • H&N Baracuda Match
  • Summary of this test
  • Bug Buster scope and P.O.I. mounts

Today we start looking at the accuracy of the new .177 caliber Umarex Gauntlet. I think this report will be interesting to many of you. Let’s get started.

JSB Exact Heavy

The rifle was already sighted-in from the last report, so I loaded 10 JSB Exact Heavy pellets into the magazine and started shooting from 25 yards. Yes — I said 10 pellets. I forgot about skipping pellet number 2 and loaded the entire magazine. Shot one went fine but the mag jammed on shot 2. I didn’t force it. I just pushed it out and resumed shooting. This target has 9 pellets instead of 10, and they made a very vertical group at 25 yards that measures 0.704 inches between centers. read more

  • JSB Exact Heavy
  • Magazine is easy
  • H&N Baracuda Match 4.50mm heads
  • Trigger
  • Wind picked up
  • Crosman Premier heavies
  • Evaluation

Today we will finish the report on the .177 caliber Kral Puncher Breaker bullpup PCP. I have taken longer to write this report because of the weather here in Texas. We have had a cold wet winter that has kept me off the outdoor range, and today’s test is the one at 50 yards. I learned a lot about the rifle in this test and when you see the results I think you will agree.

The test

I shot the rifle off a bench with a sandbag rest. The targets were 50 yards away and I shot 10-shot groups. Not only will I describe how the rifle shot, I’ll also give you a lot more detail on things like the trigger pull. read more
