I’m at the Pyramyd Air Cup today. Veteran readers please help the new guys with their questions while I’m gone, because I won’t have much chance to answer email. I will be back in the office on Monday.

Today we begin looking at the velocity of the Benjamin 310 BB gun. There have been so many comments and requests for me to test different things with this gun that I won’t get through the whole velocity portion today. But I will get a start.

Hollow bolt

I mentioned the hollow bolt nose that differentiates the 310 from other Benjamin air rifles, but I don’t think all of you understood what I was talking about. I remember the first time I encountered this as a kid, it fooled me, too. read more

This report covers:

  • Smoothbore single shot
  • Trigger
  • Sights
  • Size and weight
  • How many pumps?
  • Manual
  • Adjust bolt for best air seal
  • Walnut stock and pump handle
  • Summary

Today we continue our look at the Benjamin 310 BB gun.

Smoothbore single shot

I make no attempt at hiding the fact that I like single shot rifles and guns. Usually their actions are simple enough that there is flexibility to do things you can’t with a repeater. For example, I had a problem with lead balls jamming in the Benjamin 700, and there is no easy way to clear the jam. The 700 action is all buttoned up. But the 310 is a simple bolt action that will allow me to test varying sizes of lead balls. If one gets stuck all I have to do is rod it out and keep on going. read more

Two months ago I attended a small local gun show where the joke is — if you are looking for Indian jewelry, coffee mugs and dream catchers, this is the gun show to attend! Guns? Not so much. But it’s local, so I went. I haven’t had much luck at this show — ever! But because it’s mentioned the intro to this report, you know this time will be different.

I was halfway through the show, looking carefully at everything on each table when my buddy Otho called to me. He was on point the next aisle over. Oh great, I thought. Another rusty Daisy Red Ryder from 1986! But I was wrong. read more

This report covers:

  • Clearing the jam
  • The jam
  • Assembly
  • Accuracy
  • Re-sighting
  • Crosman Premiers
  • Crosman wadcutters
  • 10-shots
  • Discussion
  • Summary

You may recall that the Crosman 102 jammed last time I tested it and I had to clear it before continuing. I did that and today we will shoot it at 25 yards. First, let’s clear the jam.

Clearing the jam

Crosman designed the 102 to be easy to clear, but without a manual I had to discover it for myself. The rear peep sight slides to either side, revealing a hole through which many jammed pellets can be removed.

Crosman 102 jam hole
Pull the bolt back and rod the pellet out of the breech. It will fall out this hole.

My jam was more involved, though, and I had to partially disassemble the action to clear it. The top receiver cover is held on by one shoulder bolt that has a large thumbscrew head. Remove it and the top cover slides back and off the receiver. The peep sight is attached to the cover by a rivet and comes off with the cover. read more

This report covers:

  • Test 1. How many pumps?
  • Test 2. RWS Hobby pellets
  • Test 3. Sig Match Ballistic Alloy pellets
  • How stable?
  • The pump stroke
  • Pump force
  • Rear sight fix
  • Trigger pull
  • Summary

Today we look at the power and velocity of the vintage Crosman 105 Bullseye multi-pump pneumatic pistol. I said in Part 1 that I would be surprised if this pistol breaks 450 f.p.s. Well, surprise, surprise! It didn’t even go that fast. And, that is what today’s report is all about, so let’s get started.

Test 1. How many pumps?

I looked through my library and didn’t find a manual for the 105. Crosman has a PDF online, or what they call a manual, but it’s just  a parts list and disassembly procedure. But in that document they do say to test your valve by filling the gun 6 pumps and then looking for bubbles around all the exit places. Oddly I found that 6 pumps is one too many for this particular gun. Let’s see now. read more

This report covers:

  • More than one shot per fill?
  • How many pumps?
  • The test
  • Sights
  • Pellet feed
  • RWS Meisterkugeln
  • Crosman wadcutters
  • RWS Hobbys
  • Crosman Premiers
  • Now 10 shots
  • Discussion
  • Summary

Today we look at the accuracy of the Crosman 102 repeating multi-pump pellet rifle. The last time I shot this rifle was back before the SHOT Show in January. I kept putting it off for no reason that I can remember.

More than one shot per fill?

Since it is a repeater, does it get more than one shot per fill? It’s not supposed to. There are multi-pumps that do get more than one shot per fill and I will be covering one of them for you — a rare Benjamin 700. But that’s not today. The 102 has to be pumped for every shot.

How many pumps?

If you take the time to read Part 2 you will see that I discovered that this rifle doesn’t need more than 5 pump strokes to achieve its best velocity. I tested it to 8 strokes, but after 5 strokes the velocity increase got really small. read more

Today I moved back to 25 yards to test the Sheridan Supergrade. There were also a couple extra tests readers asked me to do and they are included in this report.

The test

I shot with the rifle rested on a sandbag. I pumped the rifle 5 times for every shot in today’s report. I also wore my reading glasses to make the front sight as sharp as possible. The bullseye became a little fuzzier than usual, but I think you are going to see that it didn’t matter. read more
