This report covers:

  • How to test?
  • RWS Hobby
  • H&N Baracuda Match
  • One pump
  • Another test
  • Fastest shot
  • Pellet tests coming
  • One final test
  • Summary

Today is our final day of looking at the velocity of the Benjamin 310 multi-pump BB gun. You will recall that the reason this has taken so long is because this gun is very flexible about the ammo it accepts. If it turns out to be accurate, this gun may well be an all-time best airgun to own — right up there with an FWB 124 and a Diana 27..

Today we will look at the velocity with pellets. Since the gun is smoothbore I don’t expect it to be accurate past 10 meters, but I will reserve judgement until we test it. If I get nothing better than 2-inches at that distance, though, I won’t be testing it at 25 yards. There are already enough holes in my walls and woodwork! read more


Crosman DPMS SBR full-auto BB gun: Part 1

Crosman’s DPMS SBR full auto BB gun.

This report covers:

  • What is it?
  • Watch the video
  • The gun
  • Blowback
  • Controls
  • Disassembly
  • Stock
  • Forearm
  • Loading
  • Shot count
  • Bolt holdopen
  • Sights
  • Summary

Today we begin looking at the Crosman DPMS SBR full-auto BB gun. First — the acronyms. DPMS = Defense Procurement Manufacturing Services. WHAT??? It’s a shop that was initially in Osseo, Minnesota and opened in 1985. It started manufacturing parts for military weapons like the M16. It’s now part of a larger conglomerate that’s located in Huntsville, Alabama. SBR = Short Barrel Rifle. Another name for a carbine, and, in this case, the rifle that was shortened was already a carbine.

What is it?

The DPMS SBR is Crosman’s select-fire BB gun that shoots 25 BBs per magazine. Select fire means both full and semiautomatic fire are available via the conventional M16 selector switch. Gun bashers will tell you that AR-15s are automatic, but in fact that is incorrect. Civilians in the U.S. may not purchase full auto firearms without a lengthy process that vets the owner, tying the gun to him by serial number, and costs $200 per firearm so registered. AR-15s are semiautomatic, only, so a selector switch applies to the full auto military platform, only. read more


Seneca Double Shot air shotgun: Part 1

Seneca Double Shot
Air Venturi’s Seneca Double Shot air shotgun.

This report covers:

  • Fast second shot
  • Let’s review
  • Sub-1 crossbow
  • Reality of bow hunting
  • Description
  • How many shots?
  • What it shoots
  • Is this for you?
  • Summary

I usually just review the products and leave my personal opinions out — or I try to weave them in under the radar. Not today. I first saw today’s subject airgun, the Seneca Double Shot air shotgun at the 2018 SHOT Show. I looked at it and then showed it to Rossi Morreale on American Airgunner, all the while wondering — WHY? What possible use is there for a double-barreled air shotgun? Then Val Gamerman, the president of Pyramyd Air, told me. The extra barrel gives you a fast second shot.

Fast second shot

That second barrel gives you a quick second shot at a deer or other large game animal, when you are using Air Venturi Air Bolts. Nuff said! That is a real reason for owning a double-barreled air shotgun. read more

Stormrider Gen 1 Part 4

This report covers:

  • Fill
  • RWS Superdome
  • Discharge sound
  • JSB Exact Heavy
  • Chronograph
  • Last pellet
  • Discussion
  • Trigger pull and adjustment
  • Summary

Today we look at the velocity of the .177-caliber Diana Stormrider. I linked to Part 4 of my test of the .22 caliber rifle last year for comparison, but the rifle I’m testing today is a .177-caliber second-generation airgun, where that last test was a first generation. Part 1 of this report discusses the differences.

In Part 1 of this report I made a big deal about this Stormrider’s fill adaptor coming with a male Foster fitting on the end that connects to the hose of most air tanks. However, in re-reading the other report I see that the Gen 1 gun had one, as well, so Diana has thought this through from the very beginning. read more

This report covers:

  • Smart Shot
  • 4.4mm balls
  • 4.45mm balls
  • Beeman Perfect Rounds
  • Darts and bolts
  • Airgun darts
  • Bolts
  • Airgun bolts
  • Bolt extraction
  • Not finished yet

Today I will almost complete the velocity test of the Benjamin 310 BB gun. Today we look at the velocity with lead balls and also with both kinds of darts. Lead balls are first.

I don’t plan on testing each lead ball exhaustively. If I find something interesting I can always expand that particular test. And I will exhaust all the air before each shot I record, so you know it is moving that fast on just those pumps.

Smart Shot

H&N Smart Shot measure 0.1725-inches, nominally. Here is their performance. read more

Benjamin Fortitude

This report covers:

  • Second rifle
  • Crosman Premier lites
  • JSB Exact Heavy
  • Trigger
  • Air Arms Falcons
  • Premier lites again
  • Shot count
  • Discharge sound
  • Test target
  • Evaluation

Today we resume our look at the Benjamin Fortitude precharged air rifle. I will summarize where we have been, so folks reading this report for the first time will understand what is happening.

Second rifle

This is the second Fortitude I have tested. Parts 1 and 2 of this report belong to the first rifle. The first rifle’s inlet valve locked up at the end of the velocity test and remained open when I bled the air after the fill. The entire gun exhausted all its air. I tried to fill it several times, just to be sure. So I stopped the test at that point and requested a replacement rifle in the same .177 caliber. While this is Part 3, I will actually run another velocity test today, since this is a brand new airgun. read more

This report covers:

  • Tightened shroud
  • The test
  • Pellets
  • Magazine tested
  • Sight in
  • Magazine again
  • Adjusted the scope
  • Quiet!
  • Trigger
  • JSB Exact Heavy
  • Magazine acting up
  • Premier Heavy single shot
  • Summary

Today I test the Umarex Gauntlet PCP rifle at 50 yards, to see whether tightening the barrel shroud makes a difference to accuracy. I had planned to finish the report with Part 8, which was already more testing than I normally give a modern air rifle, but this is the rifle that defined the price point PCPs and it deserved a close look.

Tightened shroud

Reader GunFun1 asked me to check to see whether the barrel shroud was tight after my last test. It wasn’t, so I agreed to this additional test. I tightened the barrel shroud before the test began, and it stayed tight for the whole test. I wasn’t going to get it wrong this time! read more
